- codecs are no longer searched by read_header() (should fix ffserver
|
||||
segfault)
|
||||
|
||||
|
||||
|
||||
version 0.4.3:
|
||||
|
||||
- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)
|
||||
- fixed raw yuv output
|
||||
- added motion rounding support in MPEG-4
|
||||
- fixed motion bug rounding in MSMPEG4
|
||||
- added B-frame handling in video core
|
||||
- added full MPEG-1 decoding support
|
||||
- added partial (frame only) MPEG-2 support
|
||||
- changed the FOURCC code for H.263 to "U263" to be able to see the
|
||||
+AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
|
||||
this +codec ;) (JuanJo).
|
||||
- Halfpel motion estimation after MB type selection (JuanJo)
|
||||
- added pgm and .Y.U.V output format
|
||||
- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
|
||||
output.
|
||||
- added pgmpipe I/O format (original patch from Martin Aumueller
|
||||
<lists at reserv.at>, but changed completely since we use a format
|
||||
instead of a protocol)
|
||||
|
||||
|
||||
|
||||
version 0.4.2:
|
||||
|
||||
- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
|
||||
(for OpenDivX) is almost complete: 8x8 MVs and rounding are
|
||||
missing. MSMPEG4 support is complete.
|
||||
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
|
||||
can decode ffmpeg MPEGs :-)).
|
||||
- added libavcodec API documentation (see apiexample.c).
|
||||
- fixed image polyphase bug (the bottom of some images could be
|
||||
greenish)
|
||||
- added support for non clipped motion vectors (decoding only)
|
||||
and image sizes non-multiple of 16
|
||||
- added support for AC prediction (decoding only)
|
||||
- added file overwrite confirmation (can be disabled with -y)
|
||||
- added custom size picture to H.263 using H.263+ (Juanjo)
|
||||
|
||||
|
||||
version 0.4.1:
|
||||
|
||||
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
|
||||
of AVI and ASF to DIV3.
|
||||
- added -me option to set motion estimation method
|
||||
(default=log). suppressed redundant -hq option.
|
||||
- added options -acodec and -vcodec to force a given codec (useful for
|
||||
AVI for example)
|
||||
- fixed -an option
|
||||
- improved dct_quantize speed
|
||||
- factorized some motion estimation code
|
||||
|
||||
|
||||
|
||||
version 0.4.0:
|
||||
|
||||
- removing grab code from ffserver and moved it to ffmpeg. Added
|
||||
multistream support to ffmpeg.
|
||||
- added timeshifting support for live feeds (option ?date=xxx in the
|
||||
URL)
|
||||
- added high quality image resize code with polyphase filter (need
|
||||
mmx/see optimization). Enable multiple image size support in ffserver.
|
||||
- added multi live feed support in ffserver
|
||||
- suppressed master feature from ffserver (it should be done with an
|
||||
external program which opens the .ffm url and writes it to another
|
||||
ffserver)
|
||||
- added preliminary support for video stream parsing (WAV and AVI half
|
||||
done). Added proper support for audio/video file conversion in
|
||||
ffmpeg.
|
||||
- added preliminary support for video file sending from ffserver
|
||||
- redesigning I/O subsystem: now using URL based input and output
|
||||
(see avio.h)
|
||||
- added WAV format support
|
||||
- added "tty user interface" to ffmpeg to stop grabbing gracefully
|
||||
- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
|
||||
(Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
|
||||
- added MMX DCT from mpeg2_movie 1.5 (Juanjo)
|
||||
- added new motion estimation algorithms, log and phods (Juanjo)
|
||||
- changed directories: libav for format handling, libavcodec for
|
||||
codecs
|
||||
|
||||
|
||||
|
||||
version 0.3.4:
|
||||
|
||||
- added stereo in MPEG audio encoder
|
||||
|
||||
|
||||
|
||||
version 0.3.3:
|
||||
|
||||
- added 'high quality' mode which use motion vectors. It can be used in
|
||||
real time at low resolution.
|
||||
- fixed rounding problems which caused quality problems at high
|
||||
bitrates and large GOP size
|
||||
|
||||
|
||||
|
||||
version 0.3.2: small fixes
|
||||
|
||||
- ASF fixes
|
||||
- put_seek bug fix
|
||||
|
||||
|
||||
|
||||
version 0.3.1: added avi/divx support
|
||||
|
||||
- added AVI support
|
||||
- added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
|
||||
- added sound for flash format (not tested)

Release Notes
|
||||
=============
|
||||
|
||||
* 0.8 "Love" June, 2011
|
||||
* 0.7.1 "Peace" June, 2011 (identical to 0.8 but using 0.6 ABI/API)
|
||||
|
||||
|
||||
General notes
|
||||
-------------
|
||||
|
||||
This release enables frame-based multithreaded decoding for a number of codecs,
|
||||
including theora, huffyuv, VP8, H.263, mpeg4 and H.264. Additionally, there has
|
||||
been a major cleanup of
|
||||
both internal and external APIs. For this reason, the major versions of all
|
||||
libraries except libpostproc have been bumped. This means that 0.8 can be installed
|
||||
side-by-side with previous releases, on the other hand applications need to be
|
||||
recompiled to use 0.8.
|
||||
|
||||
Other important changes are more than 200 bugfixes, known regressions were fixed
|
||||
w.r.t 0.5 and 0.6, additions of decoders including, but not limited to,
|
||||
AMR-WB, single stream LATM/LOAS, G.722 ADPCM, a native VP8 decoder
|
||||
and HE-AACv2. Additionally, many new de/muxers such as WebM in Matroska, Apple
|
||||
HTTP Live Streaming, SAP, IEC 61937 (S/PDIF) have been added.
|
||||
|
||||
See the Changelog file for a list of significant changes.
|
||||
|
||||
Bugreports against FFmpeg git master or the most recent FFmpeg release are
|
||||
accepted. If you are experiencing issues with any formally released version of
|
||||
FFmpeg, please try git master to check if the issue still exists. If it does,
|
||||
make your report against the development code following the usual bug reporting
|
||||
guidelines.
|
||||
|
||||
Note, if you have difficulty building for mingw, try --disable-outdev=sdl
|
||||
|
||||
|
||||
API changes
|
||||
-----------
|
||||
|
||||
Please see git log of the public headers or the file doc/APIchanges for
|
||||
programmer-centric information. Note that some long-time deprecated APIs have
|
||||
been removed. Also, a number of additional APIs have been deprecated and might
|
||||
be removed in the next release.

Convert MJPEG/AVI1 packets to full JPEG/JFIF packets.
|
||||
|
||||
MJPEG is a video codec wherein each video frame is essentially a
|
||||
JPEG image. The individual frames can be extracted without loss,
|
||||
e.g. by
|
||||
|
||||
@example
|
||||
ffmpeg -i ../some_mjpeg.avi -vcodec copy frames_%d.jpg
|
||||
@end example
|
||||
|
||||
Unfortunately, these chunks are incomplete JPEG images, because
|
||||
they lack the DHT segment required for decoding. Quoting from
|
||||
@url{http://www.digitalpreservation.gov/formats/fdd/fdd000063.shtml}:
|
||||
|
||||
Avery Lee, writing in the rec.video.desktop newsgroup in 2001,
|
||||
commented that "MJPEG, or at least the MJPEG in AVIs having the
|
||||
MJPG fourcc, is restricted JPEG with a fixed -- and *omitted* --
|
||||
Huffman table. The JPEG must be YCbCr colorspace, it must be 4:2:2,
|
||||
and it must use basic Huffman encoding, not arithmetic or
|
||||
progressive. . . . You can indeed extract the MJPEG frames and
|
||||
decode them with a regular JPEG decoder, but you have to prepend
|
||||
the DHT segment to them, or else the decoder won't have any idea
|
||||
how to decompress the data. The exact table necessary is given in
|
||||
the OpenDML spec."
|
||||
|
||||
This bitstream filter patches the header of frames extracted from an MJPEG
|
||||
stream (carrying the AVI1 header ID and lacking a DHT segment) to
|
||||
produce fully qualified JPEG images.
|
||||
|
||||
@example
|
||||
ffmpeg -i mjpeg-movie.avi -vcodec copy -vbsf mjpeg2jpeg frame_%d.jpg
|
||||
exiftran -i -9 frame*.jpg
|
||||
ffmpeg -i frame_%d.jpg -vcodec copy rotated.avi

When you configure your FFmpeg build, all the supported demuxers
|
||||
are enabled by default. You can list all available ones using the
|
||||
configure option "--list-demuxers".
|
||||
|
||||
You can disable all the demuxers using the configure option
|
||||
"--disable-demuxers", and selectively enable a single demuxer with
|
||||
the option "--enable-demuxer=@var{DEMUXER}", or disable it
|
||||
with the option "--disable-demuxer=@var{DEMUXER}".
|
||||
|
||||
The option "-formats" of the ff* tools will display the list of
|
||||
enabled demuxers.
|
||||
|
||||
The description of some of the currently available demuxers follows.
|
||||
|
||||
@section image2
|
||||
|
||||
Image file demuxer.
|
||||
|
||||
This demuxer reads from a list of image files specified by a pattern.
|
||||
|
||||
The pattern may contain the string "%d" or "%0@var{N}d", which
|
||||
specifies the position of the characters representing a sequential
|
||||
number in each filename matched by the pattern. If the form
|
||||
"%d0@var{N}d" is used, the string representing the number in each
|
||||
filename is 0-padded and @var{N} is the total number of 0-padded
|
||||
digits representing the number. The literal character '%' can be
|
||||
specified in the pattern with the string "%%".
|
||||
|
||||
If the pattern contains "%d" or "%0@var{N}d", the first filename of
|
||||
the file list specified by the pattern must contain a number
|
||||
inclusively contained between 0 and 4, all the following numbers must
|
||||
be sequential. This limitation may be hopefully fixed.
|
||||
|
||||
The pattern may contain a suffix which is used to automatically
|
||||
determine the format of the images contained in the files.
|
||||
|
||||
For example the pattern "img-%03d.bmp" will match a sequence of
|
||||
filenames of the form @file{img-001.bmp}, @file{img-002.bmp}, ...,
|
||||
@file{img-010.bmp}, etc.; the pattern "i%%m%%g-%d.jpg" will match a
|
||||
sequence of filenames of the form @file{i%m%g-1.jpg},
|
||||
@file{i%m%g-2.jpg}, ..., @file{i%m%g-10.jpg}, etc.
|
||||
|
||||
The size, the pixel format, and the format of each image must be the
|
||||
same for all the files in the sequence.
|
||||
|
||||
The following example shows how to use @file{ffmpeg} for creating a
|
||||
video from the images in the file sequence @file{img-001.jpeg},
|
||||
@file{img-002.jpeg}, ..., assuming an input framerate of 10 frames per
|
||||
second:
|
||||
@example
|
||||
ffmpeg -r 10 -f image2 -i 'img-%03d.jpeg' out.avi
|
||||
@end example
|
||||
|
||||
Note that the pattern must not necessarily contain "%d" or
|
||||
"%0@var{N}d", for example to convert a single image file
|
||||
@file{img.jpeg} you can employ the command:
|
||||
@example
|
||||
ffmpeg -f image2 -i img.jpeg img.png
|
||||
@end example
|
||||
|
||||
@section applehttp
|
||||
|
||||
Apple HTTP Live Streaming demuxer.
|
||||
|
||||
This demuxer presents all AVStreams from all variant streams.
|
||||
The id field is set to the bitrate variant index number. By setting
|
||||
the discard flags on AVStreams (by pressing 'a' or 'v' in ffplay),
|
||||
the caller can decide which variant streams to actually receive.
|
||||
The total bitrate of the variant that the stream belongs to is
|
||||
available in a metadata key named "variant_bitrate".

|

Encoders are configured elements in FFmpeg which allow the encoding of
|
||||
multimedia streams.
|
||||
|
||||
When you configure your FFmpeg build, all the supported native encoders
|
||||
are enabled by default. Encoders requiring an external library must be enabled
|
||||
manually via the corresponding @code{--enable-lib} option. You can list all
|
||||
available encoders using the configure option @code{--list-encoders}.
|
||||
|
||||
You can disable all the encoders with the configure option
|
||||
@code{--disable-encoders} and selectively enable / disable single encoders

@chapter Audio Encoders
|

@c man begin AUDIO ENCODERS
|
||||
|
||||
A description of some of the currently available audio encoders
|
||||
follows.
|
||||
|
||||
@section ac3 and ac3_fixed
|
||||
|
||||
AC-3 audio encoders.
|
||||
|
||||
These encoders implement part of ATSC A/52:2010 and ETSI TS 102 366, as well as
|
||||
the undocumented RealAudio 3 (a.k.a. dnet).
|
||||
|
||||
The @var{ac3} encoder uses floating-point math, while the @var{ac3_fixed}
|
||||
encoder only uses fixed-point integer math. This does not mean that one is
|
||||
always faster, just that one or the other may be better suited to a
|
||||
particular system. The floating-point encoder will generally produce better
|
||||
quality audio for a given bitrate. The @var{ac3_fixed} encoder is not the
|
||||
default codec for any of the output formats, so it must be specified explicitly
|
||||
using the option @code{-acodec ac3_fixed} in order to use it.
|
||||
|
||||
@subsection AC-3 Metadata
|
||||
|
||||
The AC-3 metadata options are used to set parameters that describe the audio,
|
||||
but in most cases do not affect the audio encoding itself. Some of the options
|
||||
do directly affect or influence the decoding and playback of the resulting
|
||||
bitstream, while others are just for informational purposes. A few of the
|
||||
options will add bits to the output stream that could otherwise be used for
|
||||
audio data, and will thus affect the quality of the output. Those will be
|
||||
indicated accordingly with a note in the option list below.
|
||||
|
||||
These parameters are described in detail in several publicly-available
|
||||
documents.

@subsection Extended Bitstream Information
|
||||
The extended bitstream options are part of the Alternate Bit Stream Syntax as
|
||||
specified in Annex D of the A/52:2010 standard. It is grouped into 2 parts.
|
||||
If any one parameter in a group is specified, all values in that group will be
|
||||
written to the bitstream. Default values are used for those that are written
|
||||
but have not been specified. If the mixing levels are written, the decoder
|
||||
will use these values instead of the ones specified in the @code{center_mixlev}
|
||||
and @code{surround_mixlev} options if it supports the Alternate Bit Stream
|
||||
Syntax.

@item -channel_coupling @var{boolean}
|

Enables/Disables use of channel coupling, which is an optional AC-3 feature
|

that increases quality by combining high frequency information from multiple
|
||||
channels into a single channel. The per-channel high frequency information is
|
||||
sent with less accuracy in both the frequency and time domains. This allows
|
||||
more bits to be used for lower frequencies while preserving enough information
|
||||
to reconstruct the high frequencies. This option is enabled by default for the
|
||||
floating-point encoder and should generally be left as enabled except for
|
||||
testing purposes or to increase encoding speed.

@chapter Expression Evaluation
|
||||
@c man begin EXPRESSION EVALUATION
|
||||
|
||||
When evaluating an arithemetic expression, FFmpeg uses an internal
|
||||
formula evaluator, implemented through the @file{libavutil/eval.h}
|
||||
interface.
|
||||
|
||||
An expression may contain unary, binary operators, constants, and
|
||||
functions.
|
||||
|
||||
Two expressions @var{expr1} and @var{expr2} can be combined to form
|
||||
another expression "@var{expr1};@var{expr2}".
|
||||
@var{expr1} and @var{expr2} are evaluated in turn, and the new
|
||||
expression evaluates to the value of @var{expr2}.
|
||||
|
||||
The following binary operators are available: @code{+}, @code{-},
|
||||
@code{*}, @code{/}, @code{^}.
|
||||
|
||||
The following unary operators are available: @code{+}, @code{-}.
|
||||
|
||||
The following functions are available:
|
||||
@table @option

||||
@item gt(x, y)
|
||||
@item lte(x, y)
|
||||
@item lt(x, y)
|
||||
@item st(var, expr)
|
||||
Allow to store the value of the expression @var{expr} in an internal
|
||||
variable. @var{var} specifies the number of the variable where to
|
||||
store the value, and it is a value ranging from 0 to 9. The function
|
||||
returns the value stored in the internal variable.
|
||||
|
||||
@item ld(var)
|
||||
Allow to load the value of the internal variable with number
|
||||
@var{var}, which was previosly stored with st(@var{var}, @var{expr}).
|
||||
The function returns the loaded value.
|
||||
|
||||
@item while(cond, expr)
|
||||
Evaluate expression @var{expr} while the expression @var{cond} is
|
||||
non-zero, and returns the value of the last @var{expr} evaluation, or
|
||||
NAN if @var{cond} was always false.
|
||||
|
||||
@item ceil(expr)
|
||||
Round the value of expression @var{expr} upwards to the nearest
|
||||
integer. For example, "ceil(1.5)" is "2.0".
|
||||
|
||||
@item floor(expr)
|
||||
Round the value of expression @var{expr} downwards to the nearest
|
||||
integer. For example, "floor(-1.5)" is "-2.0".
|
||||
|
||||
@item trunc(expr)
|
||||
Round the value of expression @var{expr} towards zero to the nearest
|
||||
integer. For example, "trunc(-1.5)" is "-1.0".
|
||||
|
||||
@item sqrt(expr)
|
||||
Compute the square root of @var{expr}. This is equivalent to
|
||||
"(@var{expr})^.5".
|
||||
|
||||
@item not(expr)
|
||||
Return 1.0 if @var{expr} is zero, 0.0 otherwise.
|
||||
|
||||
@item pow(x, y)
|
||||
Compute the power of @var{x} elevated @var{y}, it is equivalent to
|
||||
"(@var{x})^(@var{y})".
|
||||
@end table
|
||||
|
||||
Note that:
|
||||
|
||||
@code{*} works like AND
|
||||
|
||||
@code{+} works like OR
|
||||
|
||||
thus
|
||||
@example
|
||||
if A then B else C
|
||||
@end example
|
||||
is equivalent to
|
||||
@example
|
||||
A*B + not(A)*C
|
||||
@end example
|
||||
|
||||
In your C code, you can extend the list of unary and binary functions,
|
||||
and define recognized constants, so that they are available for your
|
||||
expressions.
|
||||
|
||||
The evaluator also recognizes the International System number
|
||||
postfixes. If 'i' is appended after the postfix, powers of 2 are used
|
||||
instead of powers of 10. The 'B' postfix multiplies the value for 8,
|
||||
and can be appended after another postfix or used alone. This allows
|
||||

FATE Automated Testing Environment
|
||||
|
||||
FATE provides a regression testsuite that can be run locally or configured
|
||||
to send reports to fate.ffmpeg.org.
|
||||
In order to run, it needs a large amount of data (samples and references)
|
||||
that is provided separately from the actual source distribution.
|
||||
|
||||
Use the following command to get the fate test samples
|
||||
|
||||
# make fate-rsync SAMPLES=fate-suite/
|
||||
|
||||
To inform the build system about the testsuite location, pass
|
||||
`--samples=<path to the samples>` to configure or set the SAMPLES Make
|
||||
variable or the FATE_SAMPLES environment variable to a suitable value.
|

FFmpeg & evaluating performance on the PowerPC Architecture HOWTO
|
||||
|
||||
(c) 2003-2004 Romain Dolbeau <romain@dolbeau.org>
|
||||
|
||||
|
||||
|
||||
I - Introduction
|
||||
|
||||
The PowerPC architecture and its SIMD extension AltiVec offer some
|
||||
interesting tools to evaluate performance and improve the code.
|
||||
This document tries to explain how to use those tools with FFmpeg.
|
||||
|
||||
The architecture itself offers two ways to evaluate the performance of
|
||||
a given piece of code:
|
||||
|
||||
1) The Time Base Registers (TBL)
|
||||
2) The Performance Monitor Counter Registers (PMC)
|
||||
|
||||
The first ones are always available, always active, but they're not very
|
||||
accurate: the registers increment by one every four *bus* cycles. On
|
||||
my 667 Mhz tiBook (ppc7450), this means once every twenty *processor*
|
||||
cycles. So we won't use that.
|
||||
|
||||
The PMC are much more useful: not only can they report cycle-accurate
|
||||
timing, but they can also be used to monitor many other parameters,
|
||||
such as the number of AltiVec stalls for every kind of instruction,
|
||||
or instruction cache misses. The downside is that not all processors
|
||||
support the PMC (all G3, all G4 and the 970 do support them), and
|
||||
they're inactive by default - you need to activate them with a
|
||||
dedicated tool. Also, the number of available PMC depends on the
|
||||
procesor: the various 604 have 2, the various 75x (aka. G3) have 4,
|
||||
and the various 74xx (aka G4) have 6.
|
||||
|
||||
*WARNING*: The PowerPC 970 is not very well documented, and its PMC
|
||||
registers are 64 bits wide. To properly notify the code, you *must*
|
||||
tune for the 970 (using --tune=970), or the code will assume 32 bit
|
||||
registers.
|
||||
|
||||
|
||||
II - Enabling FFmpeg PowerPC performance support
|
||||
|
||||
This needs to be done by hand. First, you need to configure FFmpeg as
|
||||
usual, but add the "--powerpc-perf-enable" option. For instance:
|
||||
|
||||
#####
|
||||
./configure --prefix=/usr/local/ffmpeg-svn --cc=gcc-3.3 --tune=7450 --powerpc-perf-enable
|
||||
#####
|
||||
|
||||
This will configure FFmpeg to install inside /usr/local/ffmpeg-svn,
|
||||
compiling with gcc-3.3 (you should try to use this one or a newer
|
||||
gcc), and tuning for the PowerPC 7450 (i.e. the newer G4; as a rule of
|
||||
thumb, those at 550Mhz and more). It will also enable the PMC.
|
||||
|
||||
You may also edit the file "config.h" to enable the following line:
|
||||
|
||||
#####
|
||||
// #define ALTIVEC_USE_REFERENCE_C_CODE 1
|
||||
#####
|
||||
|
||||
If you enable this line, then the code will not make use of AltiVec,
|
||||
but will use the reference C code instead. This is useful to compare
|
||||
performance between two versions of the code.
|
||||
|
||||
Also, the number of enabled PMC is defined in "libavcodec/ppc/dsputil_ppc.h":
|
||||
|
||||
#####
|
||||
#define POWERPC_NUM_PMC_ENABLED 4
|
||||
#####
|
||||
|
||||
If you have a G4 CPU, you can enable all 6 PMC. DO NOT enable more
|
||||
PMC than available on your CPU!
|
||||
|
||||
Then, simply compile FFmpeg as usual (make && make install).
|
||||
|
||||
|
||||
|
||||
III - Using FFmpeg PowerPC performance support
|
||||
|
||||
This FFmeg can be used exactly as usual. But before exiting, FFmpeg
|
||||
will dump a per-function report that looks like this:
|
||||
|
||||
#####
|
||||
PowerPC performance report
|
||||
Values are from the PMC registers, and represent whatever the
|
||||
registers are set to record.
|
||||
Function "gmc1_altivec" (pmc1):
|
||||
min: 231
|
||||
max: 1339867
|
||||
avg: 558.25 (255302)
|
||||
Function "gmc1_altivec" (pmc2):
|
||||
min: 93
|
||||
max: 2164
|
||||
avg: 267.31 (255302)
|
||||
Function "gmc1_altivec" (pmc3):
|
||||
min: 72
|
||||
max: 1987
|
||||
avg: 276.20 (255302)
|
||||
(...)
|
||||
#####
|
||||
|
||||
In this example, PMC1 was set to record CPU cycles, PMC2 was set to
|
||||
record AltiVec Permute Stall Cycles, and PMC3 was set to record AltiVec
|
||||
Issue Stalls.
|
||||
|
||||
The function "gmc1_altivec" was monitored 255302 times, and the
|
||||
minimum execution time was 231 processor cycles. The max and average
|
||||
aren't much use, as it's very likely the OS interrupted execution for
|
||||
reasons of its own :-(
|
||||
|
||||
With the exact same settings and source file, but using the reference C
|
||||
code we get:
|
||||
|
||||
#####
|
||||
PowerPC performance report
|
||||
Values are from the PMC registers, and represent whatever the
|
||||
registers are set to record.
|
||||
Function "gmc1_altivec" (pmc1):
|
||||
min: 592
|
||||
max: 2532235
|
||||
avg: 962.88 (255302)
|
||||
Function "gmc1_altivec" (pmc2):
|
||||
min: 0
|
||||
max: 33
|
||||
avg: 0.00 (255302)
|
||||
Function "gmc1_altivec" (pmc3):
|
||||
min: 0
|
||||
max: 350
|
||||
avg: 0.03 (255302)
|
||||
(...)
|
||||
#####
|
||||
|
||||
592 cycles, so the fastest AltiVec execution is about 2.5x faster than
|
||||
the fastest C execution in this example. It's not perfect but it's not
|
||||
bad (well I wrote this function so I can't say otherwise :-).
|
||||
|
||||
Once you have that kind of report, you can try to improve things by
|
||||
finding what goes wrong and fixing it; in the example above, one
|
||||
should try to diminish the number of AltiVec stalls, as this *may*
|
||||
improve performance.
|
||||
|
||||
|
||||
|
||||
IV) Enabling the PMC in Mac OS X
|
||||
|
||||
This is easy. Use "Monster" and "monster". Those tools come from
|
||||
Apple's CHUD package, and can be found hidden in the developer web
|
||||
site & FTP site. "MONster" is the graphical application, use it to
|
||||
generate a config file specifying what each register should
|
||||
monitor. Then use the command-line application "monster" to use that
|
||||
config file, and enjoy the results.
|
||||
|
||||
Note that "MONster" can be used for many other things, but it's
|
||||
documented by Apple, it's not my subject.
|
||||
|
||||
If you are using CHUD 4.4.2 or later, you'll notice that MONster is
|
||||
no longer available. It's been superseeded by Shark, where
|
||||
configuration of PMCs is available as a plugin.
|
||||
|
||||
|
||||
|
||||
V) Enabling the PMC on Linux
|
||||
|
||||
On linux you may use oprofile from http://oprofile.sf.net, depending on the
|
||||
version and the cpu you may need to apply a patch[1] to access a set of the
|
||||
possibile counters from the userspace application. You can always define them
|
||||
using the kernel interface /dev/oprofile/* .

appropriate headers and mark the data as dllimport. For example, in

libavutil/pixdesc.h you should have:

About Git write access:
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Before everything else, you should know how to use GIT properly.
|
||||
Luckily Git comes with excellent documentation.
|
||||
|
||||
git --help
|
||||
man git
|
||||
|
||||
shows you the available subcommands,
|
||||
|
||||
git <command> --help
|
||||
man git-<command>
|
||||
|
||||
shows information about the subcommand <command>.
|
||||
|
||||
The most comprehensive manual is the website Git Reference
|
||||
|
||||
http://gitref.org/
|
||||
|
||||
For more information about the Git project, visit
|
||||
|
||||
http://git-scm.com/
|
||||
|
||||
Consult these resources whenever you have problems, they are quite exhaustive.
|
||||
|
||||
You do not need a special username or password.
|
||||
All you need is to provide a ssh public key to the Git server admin.
|
||||
|
||||
What follows now is a basic introduction to Git and some FFmpeg-specific
|
||||
guidelines. Read it at least once, if you are granted commit privileges to the
|
||||
FFmpeg project you are expected to be familiar with these rules.
|
||||
|
||||
|
||||
|
||||
I. BASICS:
|
||||
==========
|
||||
|
||||
0. Get GIT:
|
||||
|
||||
You can get git from http://git-scm.com/
|
||||
|
||||
|
||||
1. Cloning the source tree:
|
||||
|
||||
git clone git://git.videolan.org/ffmpeg <target>
|
||||
|
||||
This will put the FFmpeg sources into the directory <target>.
|
||||
|
||||
git clone git@git.videolan.org:ffmpeg <target>
|
||||
|
||||
This will put the FFmpeg sources into the directory <target> and let
|
||||
you push back your changes to the remote repository.
|
||||
|
||||
|
||||
2. Updating the source tree to the latest revision:
|
||||
|
||||
git pull (--ff-only)
|
||||
|
||||
pulls in the latest changes from the tracked branch. The tracked branch
|
||||
can be remote. By default the master branch tracks the branch master in
|
||||
the remote origin.
|
||||
Caveat: Since merge commits are forbidden at least for the initial
|
||||
months of git --ff-only or --rebase (see below) are recommended.
|
||||
--ff-only will fail and not create merge commits if your branch
|
||||
has diverged (has a different history) from the tracked branch.
|
||||
|
||||
2.a Rebasing your local branches:
|
||||
|
||||
git pull --rebase
|
||||
|
||||
fetches the changes from the main repository and replays your local commits
|
||||
over it. This is required to keep all your local changes at the top of
|
||||
FFmpeg's master tree. The master tree will reject pushes with merge commits.
|
||||
|
||||
|
||||
3. Adding/removing files/directories:
|
||||
|
||||
git add [-A] <filename/dirname>
|
||||
git rm [-r] <filename/dirname>
|
||||
|
||||
GIT needs to get notified of all changes you make to your working
|
||||
directory that makes files appear or disappear.
|
||||
Line moves across files are automatically tracked.
|
||||
|
||||
|
||||
4. Showing modifications:
|
||||
|
||||
git diff <filename(s)>
|
||||
|
||||
will show all local modifications in your working directory as unified diff.
|
||||
|
||||
|
||||
5. Inspecting the changelog:
|
||||
|
||||
git log <filename(s)>
|
||||
|
||||
You may also use the graphical tools like gitview or gitk or the web
|
||||
interface available at http://git.videolan.org
|
||||
|
||||
6. Checking source tree status:
|
||||
|
||||
git status
|
||||
|
||||
detects all the changes you made and lists what actions will be taken in case
|
||||
of a commit (additions, modifications, deletions, etc.).
|
||||
|
||||
|
||||
7. Committing:
|
||||
|
||||
git diff --check
|
||||
|
||||
to double check your changes before committing them to avoid trouble later
|
||||
on. All experienced developers do this on each and every commit, no matter
|
||||
how small.
|
||||
Every one of them has been saved from looking like a fool by this many times.
|
||||
It's very easy for stray debug output or cosmetic modifications to slip in,
|
||||
please avoid problems through this extra level of scrutiny.
|
||||
|
||||
For cosmetics-only commits you should get (almost) empty output from
|
||||
|
||||
git diff -w -b <filename(s)>
|
||||
|
||||
Also check the output of
|
||||
|
||||
git status
|
||||
|
||||
to make sure you don't have untracked files or deletions.
|
||||
|
||||
git add [-i|-p|-A] <filenames/dirnames>
|
||||
|
||||
Make sure you have told git your name and email address, e.g. by running
|
||||
git config --global user.name "My Name"
|
||||
git config --global user.email my@email.invalid
|
||||
(--global to set the global configuration for all your git checkouts).
|
||||
|
||||
Git will select the changes to the files for commit. Optionally you can use
|
||||
the interactive or the patch mode to select hunk by hunk what should be
|
||||
added to the commit.
|
||||
|
||||
git commit
|
||||
|
||||
Git will commit the selected changes to your current local branch.
|
||||
|
||||
You will be prompted for a log message in an editor, which is either
|
||||
set in your personal configuration file through
|
||||
|
||||
git config core.editor
|
||||
|
||||
or set by one of the following environment variables:
|
||||
GIT_EDITOR, VISUAL or EDITOR.
|
||||
|
||||
Log messages should be concise but descriptive. Explain why you made a change,
|
||||
what you did will be obvious from the changes themselves most of the time.
|
||||
Saying just "bug fix" or "10l" is bad. Remember that people of varying skill
|
||||
levels look at and educate themselves while reading through your code. Don't
|
||||
include filenames in log messages, Git provides that information.
|
||||
|
||||
Possibly make the commit message have a terse, descriptive first line, an
|
||||
empty line and then a full description. The first line will be used to name
|
||||
the patch by git format-patch.
|
||||
|
||||
|
||||
8. Renaming/moving/copying files or contents of files:
|
||||
|
||||
Git automatically tracks such changes, making those normal commits.
|
||||
|
||||
mv/cp path/file otherpath/otherfile
|
||||
|
||||
git add [-A] .
|
||||
|
||||
git commit
|
||||
|
||||
Do not move, rename or copy files of which you are not the maintainer without
|
||||
discussing it on the mailing list first!
|
||||
|
||||
9. Reverting broken commits
|
||||
|
||||
git revert <commit>
|
||||
|
||||
git revert will generate a revert commit. This will not make the faulty
|
||||
commit disappear from the history.
|
||||
|
||||
git reset <commit>
|
||||
|
||||
git reset will uncommit the changes till <commit> rewriting the current
|
||||
branch history.
|
||||
|
||||
git commit --amend
|
||||
|
||||
allows to amend the last commit details quickly.
|
||||
|
||||
git rebase -i origin/master
|
||||
|
||||
will replay local commits over the main repository allowing to edit,
|
||||
merge or remove some of them in the process.
|
||||
|
||||
Note that the reset, commit --amend and rebase rewrite history, so you
|
||||
should use them ONLY on your local or topic branches.
|
||||
|
||||
The main repository will reject those changes.
|
||||
|
||||
10. Preparing a patchset.
|
||||
|
||||
git format-patch <commit> [-o directory]
|
||||
|
||||
will generate a set of patches out of the current branch starting from
|
||||
commit. By default the patches are created in the current directory.
|
||||
|
||||
11. Sending patches for review
|
||||
|
||||
git send-email <commit list|directory>
|
||||
|
||||
will send the patches created by git format-patch or directly generates
|
||||
them. All the email fields can be configured in the global/local
|
||||
configuration or overridden by command line.
|
||||
|
||||
12. Pushing changes to remote trees
|
||||
|
||||
git push
|
||||
|
||||
Will push the changes to the default remote (origin).
|
||||
Git will prevent you from pushing changes if the local and remote trees are
|
||||
out of sync. Refer to 2 and 2.a to sync the local tree.
|
||||
|
||||
git remote add <name> <url>
|
||||
|
||||
Will add additional remote with a name reference, it is useful if you want
|
||||
to push your local branch for review on a remote host.
|
||||
|
||||
git push <remote> <refspec>
|
||||
|
||||
Will push the changes to the remote repository. Omitting refspec makes git
|
||||
push update all the remote branches matching the local ones.
|
||||
|
||||
13. Finding a specific svn revision
|
||||
|
||||
Since version 1.7.1 git supports ':/foo' syntax for specifying commits
|
||||
based on a regular expression. see man gitrevisions
|
||||
|
||||
git show :/'as revision 23456'
|
||||
|
||||
will show the svn changeset r23456. With older git versions searching in
|
||||
the git log output is the easiest option (especially if a pager with
|
||||
search capabilities is used).
|
||||
This commit can be checked out with
|
||||
|
||||
git checkout -b svn_23456 :/'as revision 23456'
|
||||
|
||||
or for git < 1.7.1 with
|
||||
|
||||
git checkout -b svn_23456 $SHA1
|
||||
|
||||
where $SHA1 is the commit SHA1 from the 'git log' output.
|
||||
|
||||
|
||||
Contact the project admins <root at ffmpeg dot org> if you have technical
|
||||
problems with the GIT server.

@chapter Input Devices
|
||||
@c man begin INPUT DEVICES
|
||||
|
||||
Input devices are configured elements in FFmpeg which allow to access
|
||||
the data coming from a multimedia device attached to your system.
|
||||
|
||||
When you configure your FFmpeg build, all the supported input devices
|
||||
are enabled by default. You can list all available ones using the
|
||||
configure option "--list-indevs".
|
||||
|
||||
You can disable all the input devices using the configure option
|
||||
"--disable-indevs", and selectively enable an input device using the
|
||||
option "--enable-indev=@var{INDEV}", or you can disable a particular
|
||||
input device using the option "--disable-indev=@var{INDEV}".
|
||||
|
||||
The option "-formats" of the ff* tools will display the list of
|
||||
supported input devices (amongst the demuxers).
|
||||
|
||||
A description of the currently available input devices follows.
|
||||
|
||||
@section alsa
|
||||
|
||||
ALSA (Advanced Linux Sound Architecture) input device.
|
||||
|
||||
To enable this input device during configuration you need libasound
|
||||
installed on your system.
|
||||
|
||||
This device allows capturing from an ALSA device. The name of the
|
||||
device to capture has to be an ALSA card identifier.
|
||||
|
||||
An ALSA identifier has the syntax:
|
||||
@example
|
||||
hw:@var{CARD}[,@var{DEV}[,@var{SUBDEV}]]
|
||||
@end example
|
||||
|
||||
where the @var{DEV} and @var{SUBDEV} components are optional.
|
||||
|
||||
The three arguments (in order: @var{CARD},@var{DEV},@var{SUBDEV})
|
||||
specify card number or identifier, device number and subdevice number
|
||||
(-1 means any).
|
||||
|
||||
To see the list of cards currently recognized by your system check the
|
||||
files @file{/proc/asound/cards} and @file{/proc/asound/devices}.
|
||||
|
||||
For example to capture with @file{ffmpeg} from an ALSA device with
|
||||
card id 0, you may run the command:
|
||||
@example
|
||||
ffmpeg -f alsa -i hw:0 alsaout.wav
|
||||
@end example
|
||||
|
||||

|
||||
|
||||
Linux DV 1394 input device.
|
||||
|
||||
@section fbdev
|
||||
|
||||
Linux framebuffer input device.
|
||||
|
||||
The Linux framebuffer is a graphic hardware-independent abstraction
|
||||
layer to show graphics on a computer monitor, typically on the
|
||||
console. It is accessed through a file device node, usually
|
||||
@file{/dev/fb0}.
|
||||
|
||||
For more detailed information read the file
|
||||
Documentation/fb/framebuffer.txt included in the Linux source tree.
|
||||
|
||||
To record from the framebuffer device @file{/dev/fb0} with
|
||||
@file{ffmpeg}:
|
||||
@example
|
||||
ffmpeg -f fbdev -r 10 -i /dev/fb0 out.avi
|
||||
@end example
|
||||

@section jack
|
||||
|
||||
JACK input device.
|
||||
|
||||
To enable this input device during configuration you need libjack
|
||||
installed on your system.
|
||||
|
||||
A JACK input device creates one or more JACK writable clients, one for
|
||||
each audio channel, with name @var{client_name}:input_@var{N}, where
|
||||
@var{client_name} is the name provided by the application, and @var{N}
|
||||
is a number which identifies the channel.
|
||||
Each writable client will send the acquired data to the FFmpeg input
|
||||
device.
|
||||
|
||||
Once you have created one or more JACK readable clients, you need to
|
||||
connect them to one or more JACK writable clients.
|
||||
|
||||
To connect or disconnect JACK clients you can use the
|
||||
@file{jack_connect} and @file{jack_disconnect} programs, or do it
|
||||
through a graphical interface, for example with @file{qjackctl}.
|
||||
|
||||
To list the JACK clients and their properties you can invoke the command
|
||||
@file{jack_lsp}.
|
||||
|
||||
Follows an example which shows how to capture a JACK readable client
|
||||
with @file{ffmpeg}.
|
||||
@example
|
||||
# Create a JACK writable client with name "ffmpeg".
|
||||
$ ffmpeg -f jack -i ffmpeg -y out.wav
|
||||
|
||||
# Start the sample jack_metro readable client.
|
||||
$ jack_metro -b 120 -d 0.2 -f 4000
|
||||
|
||||
# List the current JACK clients.
|
||||
$ jack_lsp -c
|
||||
system:capture_1
|
||||
system:capture_2
|
||||
system:playback_1
|
||||
system:playback_2
|
||||
ffmpeg:input_1
|
||||
metro:120_bpm
|
||||
|
||||
# Connect metro to the ffmpeg writable client.
|
||||
$ jack_connect metro:120_bpm ffmpeg:input_1

@section openal
|
||||
|
||||
The OpenAL input device provides audio capture on all systems with a
|
||||
working OpenAL 1.1 implementation.
|
||||
|
||||
To enable this input device during configuration, you need OpenAL
|
||||
headers and libraries installed on your system, and need to configure
|
||||
FFmpeg with @code{--enable-openal}.
|
||||
|
||||
OpenAL headers and libraries should be provided as part of your OpenAL
|
||||
implementation, or as an additional download (an SDK). Depending on your
|
||||
installation you may need to specify additional flags via the
|
||||
@code{--extra-cflags} and @code{--extra-ldflags} for allowing the build
|
||||
system to locate the OpenAL headers and libraries.
|
||||
|
||||
An incomplete list of OpenAL implementations follows:
|
||||
|
||||
@table @strong
|
||||
@item Creative
|
||||

Portable, open source (LGPL) software implementation. Includes
|
||||
backends for the most common sound APIs on the Windows, Linux,
|
||||
Solaris, and BSD operating systems.
|
||||
See @url{http://kcat.strangesoft.net/openal.html}.
|

||||
|
||||
@section video4linux and video4linux2
|
||||
|
||||
Video4Linux and Video4Linux2 input video devices.
|
||||
|
||||
The name of the device to grab is a file device node, usually Linux
|
||||
systems tend to automatically create such nodes when the device
|
||||
(e.g. an USB webcam) is plugged into the system, and has a name of the
|
||||
kind @file{/dev/video@var{N}}, where @var{N} is a number associated to
|
||||
the device.
|
||||
|
||||
Video4Linux and Video4Linux2 devices only support a limited set of
|
||||
@var{width}x@var{height} sizes and framerates. You can check which are
|
||||
supported for example with the command @file{dov4l} for Video4Linux
|
||||
devices and the command @file{v4l-info} for Video4Linux2 devices.
|
||||
|
||||
If the size for the device is set to 0x0, the input device will
|
||||
try to autodetect the size to use.
|
||||
Only for the video4linux2 device, if the frame rate is set to 0/0 the
|
||||
input device will use the frame rate value already set in the driver.
|
||||
|
||||
Video4Linux support is deprecated since Linux 2.6.30, and will be
|
||||
dropped in later versions.
|
||||
|
||||
Follow some usage examples of the video4linux devices with the ff*
|
||||
tools.
|
||||
@example
|
||||
# Grab and show the input of a video4linux device, frame rate is set
|
||||
# to the default of 25/1.
|
||||
ffplay -s 320x240 -f video4linux /dev/video0
|
||||
|
||||
# Grab and show the input of a video4linux2 device, autoadjust size.
|
||||
ffplay -f video4linux2 /dev/video0
|
||||
|
||||
# Grab and record the input of a video4linux2 device, autoadjust size,
|
||||
# frame rate value defaults to 0/0 so it is read from the video4linux2
|
||||
# driver.
|
||||
ffmpeg -f video4linux2 -i /dev/video0 out.mpeg
|
||||
@end example
|
||||
|
||||
@section vfwcap
|
||||
|
||||
VfW (Video for Windows) capture input device.
|
||||
|
||||
The filename passed as input is the capture driver number, ranging from
|
||||
0 to 9. You may use "list" as filename to print a list of drivers. Any
|
||||
other filename will be interpreted as device number 0.
|
||||
|
||||
@section x11grab
|
||||
|
||||
X11 video input device.
|
||||
|
||||
This device allows to capture a region of an X11 display.
|
||||
|
||||
The filename passed as input has the syntax:
|
||||
@example
|
||||
[@var{hostname}]:@var{display_number}.@var{screen_number}[+@var{x_offset},@var{y_offset}]
|
||||
@end example
|
||||
|
||||
@var{hostname}:@var{display_number}.@var{screen_number} specifies the
|
||||
X11 display name of the screen to grab from. @var{hostname} can be
|
||||
ommitted, and defaults to "localhost". The environment variable
|
||||
@env{DISPLAY} contains the default display name.
|
||||
|
||||
@var{x_offset} and @var{y_offset} specify the offsets of the grabbed
|
||||
area with respect to the top-left border of the X11 screen. They
|
||||
default to 0.
|
||||
|
||||
Check the X11 documentation (e.g. man X) for more detailed information.
|
||||
|
||||
Use the @file{dpyinfo} program for getting basic information about the
|
||||
properties of your X11 display (e.g. grep for "name" or "dimensions").
|
||||
|
||||
For example to grab from @file{:0.0} using @file{ffmpeg}:
|
||||
@example
|
||||
ffmpeg -f x11grab -r 25 -s cif -i :0.0 out.mpg
|
||||
|
||||
# Grab at position 10,20.
|
||||
ffmpeg -f x11grab -r 25 -s cif -i :0.0+10,20 out.mpg
|
||||
@end example
|
||||
|
||||
@subsection @var{follow_mouse} AVOption
|
||||
|
||||
The syntax is:
|
||||
@example
|
||||
-follow_mouse centered|@var{PIXELS}
|
||||
@end example
|
||||
|
||||
When it is specified with "centered", the grabbing region follows the mouse
|
||||
pointer and keeps the pointer at the center of region; otherwise, the region
|
||||
follows only when the mouse pointer reaches within @var{PIXELS} (greater than
|
||||
zero) to the edge of region.
|
||||
|
||||
For example:
|
||||
@example
|
||||
ffmpeg -f x11grab -follow_mouse centered -r 25 -s cif -i :0.0 out.mpg
|
||||
|
||||
# Follows only when the mouse pointer reaches within 100 pixels to edge
|
||||
ffmpeg -f x11grab -follow_mouse 100 -r 25 -s cif -i :0.0 out.mpg
|
||||
@end example
|
||||
|
||||
@subsection @var{show_region} AVOption
|
||||
|
||||
The syntax is:
|
||||
@example
|
||||
-show_region 1
|
||||
@end example
|
||||
|
||||
If @var{show_region} AVOption is specified with @var{1}, then the grabbing
|
||||
region will be indicated on screen. With this option, it's easy to know what is
|
||||
being grabbed if only a portion of the screen is grabbed.
|
||||
|
||||
For example:
|
||||
@example
|
||||
ffmpeg -f x11grab -show_region 1 -r 25 -s cif -i :0.0+10,20 out.mpg
|
||||
|
||||
# With follow_mouse
|
||||
ffmpeg -f x11grab -follow_mouse centered -show_region 1 -r 25 -s cif -i :0.0 out.mpg

@chapter Available video filters
|

|
||||
When you configure your FFmpeg build, you can disable any of the
|
||||
existing video filters.
|
||||
The configure output will show the video filters included in your
|
||||
build.
|
||||
|
||||
Below is a description of the currently available video filters.
|
||||
|
||||
@section crop
|
||||
|
||||
Crop the input video to @var{x}:@var{y}:@var{width}:@var{height}.
|
||||
|
||||
@example
|
||||
./ffmpeg -i in.avi -vfilters "crop=0:0:0:240" out.avi
|
||||
@end example
|
||||
|
||||
@var{x} and @var{y} specify the position of the top-left corner of the
|
||||
output (non-cropped) area.
|
||||
|
||||
The default value of @var{x} and @var{y} is 0.
|
||||
|
||||
The @var{width} and @var{height} parameters specify the width and height
|
||||
of the output (non-cropped) area.
|
||||
|
||||
A value of 0 is interpreted as the maximum possible size contained in
|
||||
the area delimited by the top-left corner at position x:y.
|
||||
|
||||
For example the parameters:
|
||||
|
||||
@example
|
||||
"crop=100:100:0:0"
|
||||
@end example
|
||||
|
||||
will delimit the rectangle with the top-left corner placed at position
|
||||
100:100 and the right-bottom corner corresponding to the right-bottom
|
||||
corner of the input image.
|
||||
|
||||
The default value of @var{width} and @var{height} is 0.
|
||||
|
||||
@section format
|
||||
|
||||
Convert the input video to one of the specified pixel formats.
|
||||
Libavfilter will try to pick one that is supported for the input to
|
||||
the next filter.
|
||||
|
||||
The filter accepts a list of pixel format names, separated by ``:'',
|
||||
for example ``yuv420p:monow:rgb24''.
|
||||
|
||||
The following command:
|
||||
|
||||
@example
|
||||
./ffmpeg -i in.avi -vfilters "format=yuv420p" out.avi
|
||||
@end example
|
||||
|
||||
will convert the input video to the format ``yuv420p''.
|
||||
|
||||
@section noformat
|
||||
|
||||
Force libavfilter not to use any of the specified pixel formats for the
|
||||
input to the next filter.
|
||||
|
||||
The filter accepts a list of pixel format names, separated by ``:'',
|
||||
for example ``yuv420p:monow:rgb24''.
|
||||
|
||||
The following command:
|
||||
|
||||
@example
|
||||
./ffmpeg -i in.avi -vfilters "noformat=yuv420p, vflip" out.avi
|
||||
@end example
|
||||
|
||||
will make libavfilter use a format different from ``yuv420p'' for the
|
||||
input to the vflip filter.
|
||||
|
||||
@section null
|
||||
|
||||
Pass the source unchanged to the output.
|
||||
|
||||
@section scale
|
||||
|
||||
Scale the input video to @var{width}:@var{height} and/or convert the image format.
|
||||
|
||||
For example the command:
|
||||
|
||||
@example
|
||||
./ffmpeg -i in.avi -vfilters "scale=200:100" out.avi
|
||||
@end example
|
||||
|
||||
will scale the input video to a size of 200x100.
|
||||
|
||||
If the input image format is different from the format requested by
|
||||
the next filter, the scale filter will convert the input to the
|
||||
requested format.
|
||||
|
||||
If the value for @var{width} or @var{height} is 0, the respective input
|
||||
size is used for the output.
|
||||
|
||||
If the value for @var{width} or @var{height} is -1, the scale filter will
|
||||
use, for the respective output size, a value that maintains the aspect
|
||||
ratio of the input image.
|
||||
|
||||
The default value of @var{width} and @var{height} is 0.

@section slicify
|
||||
|
||||
Pass the images of input video on to next video filter as multiple
|
||||
slices.
|
||||
|
||||
@example
|
||||
./ffmpeg -i in.avi -vfilters "slicify=32" out.avi
|
||||
@end example
|
||||
|
||||
The filter accepts the slice height as parameter. If the parameter is
|
||||
not specified it will use the default value of 16.
|
||||
|
||||
Adding this in the beginning of filter chains should make filtering
|
||||
faster due to better use of the memory cache.
|
||||
|

Negative values for the amount will blur the input video, while positive
|
||||
values will sharpen. All parameters are optional and default to the
|
||||
equivalent of the string '5:5:1.0:0:0:0.0'.

@chapter Metadata
|
||||
@c man begin METADATA
|
||||
|
||||
FFmpeg is able to dump metadata from media files into a simple UTF-8-encoded
|
||||
INI-like text file and then load it back using the metadata muxer/demuxer.
|
||||
|
||||
The file format is as follows:
|
||||
@enumerate
|
||||
|
||||
@item
|
||||
A file consists of a header and a number of metadata tags divided into sections,
|
||||
each on its own line.
|
||||
|
||||
@item
|
||||
The header is a ';FFMETADATA' string, followed by a version number (now 1).
|
||||
|
||||
@item
|
||||
Metadata tags are of the form 'key=value'
|
||||
|
||||
@item
|
||||
Immediately after header follows global metadata
|
||||
|
||||
@item
|
||||
After global metadata there may be sections with per-stream/per-chapter
|
||||
metadata.
|
||||
|
||||
@item
|
||||
A section starts with the section name in uppercase (i.e. STREAM or CHAPTER) in
|
||||
brackets ('[', ']') and ends with next section or end of file.
|
||||
|
||||
@item
|
||||
At the beginning of a chapter section there may be an optional timebase to be
|
||||
used for start/end values. It must be in form 'TIMEBASE=num/den', where num and
|
||||
den are integers. If the timebase is missing then start/end times are assumed to
|
||||
be in milliseconds.
|
||||
Next a chapter section must contain chapter start and end times in form
|
||||
'START=num', 'END=num', where num is a positive integer.
|
||||
|
||||
@item
|
||||
Empty lines and lines starting with ';' or '#' are ignored.
|
||||
|
||||
@item
|
||||
Metadata keys or values containing special characters ('=', ';', '#', '\' and a
|
||||
newline) must be escaped with a backslash '\'.
|
||||
|
||||
@item
|
||||
Note that whitespace in metadata (e.g. foo = bar) is considered to be a part of
|
||||
the tag (in the example above key is 'foo ', value is ' bar').

FFmpeg multithreading methods
|
||||
==============================================
|
||||
|
||||
FFmpeg provides two methods for multithreading codecs.
|
||||
|
||||
Slice threading decodes multiple parts of a frame at the same time, using
|
||||
AVCodecContext execute() and execute2().
|
||||
|
||||
Frame threading decodes multiple frames at the same time.
|
||||
It accepts N future frames and delays decoded pictures by N-1 frames.
|
||||
The later frames are decoded in separate threads while the user is
|
||||
displaying the current one.
|
||||
|
||||
Restrictions on clients
|
||||
==============================================
|
||||
|
||||
Slice threading -
|
||||
* The client's draw_horiz_band() must be thread-safe according to the comment
|
||||
in avcodec.h.
|
||||
|
||||
Frame threading -
|
||||
* Restrictions with slice threading also apply.
|
||||
* For best performance, the client should set thread_safe_callbacks if it
|
||||
provides a thread-safe get_buffer() callback.
|
||||
* There is one frame of delay added for every thread beyond the first one.
|
||||
Clients must be able to handle this; the pkt_dts and pkt_pts fields in
|
||||
AVFrame will work as usual.
|
||||
|
||||
Restrictions on codec implementations
|
||||
==============================================
|
||||
|
||||
Slice threading -
|
||||
None except that there must be something worth executing in parallel.
|
||||
|
||||
Frame threading -
|
||||
* Codecs can only accept entire pictures per packet.
|
||||
* Codecs similar to ffv1, whose streams don't reset across frames,
|
||||
will not work because their bitstreams cannot be decoded in parallel.
|
||||
|
||||
* The contents of buffers must not be read before ff_thread_await_progress()
|
||||
has been called on them. reget_buffer() and buffer age optimizations no longer work.
|
||||
* The contents of buffers must not be written to after ff_thread_report_progress()
|
||||
has been called on them. This includes draw_edges().
|
||||
|
||||
Porting codecs to frame threading
|
||||
==============================================
|
||||
|
||||
Find all context variables that are needed by the next frame. Move all
|
||||
code changing them, as well as code calling get_buffer(), up to before
|
||||
the decode process starts. Call ff_thread_finish_setup() afterwards. If
|
||||
some code can't be moved, have update_thread_context() run it in the next
|
||||
thread.
|
||||
|
||||
If the codec allocates writable tables in its init(), add an init_thread_copy()
|
||||
which re-allocates them for other threads.
|
||||
|
||||
Add CODEC_CAP_FRAME_THREADS to the codec capabilities. There will be very little
|
||||
speed gain at this point but it should work.
|
||||
|
||||
Call ff_thread_report_progress() after some part of the current picture has decoded.
|
||||
A good place to put this is where draw_horiz_band() is called - add this if it isn't
|
||||
called anywhere, as it's useful too and the implementation is trivial when you're
|
||||
doing this. Note that draw_edges() needs to be called before reporting progress.
|
||||
|
||||
Before accessing a reference frame or its MVs, call ff_thread_await_progress().

@chapter Muxers
|
||||
@c man begin MUXERS
|
||||
|
||||
Muxers are configured elements in FFmpeg which allow writing
|
||||
multimedia streams to a particular type of file.
|
||||
|
||||
When you configure your FFmpeg build, all the supported muxers
|
||||
are enabled by default. You can list all available muxers using the
|
||||
configure option @code{--list-muxers}.
|
||||
|
||||
You can disable all the muxers with the configure option
|
||||
@code{--disable-muxers} and selectively enable / disable single muxers
|
||||
with the options @code{--enable-muxer=@var{MUXER}} /
|
||||
@code{--disable-muxer=@var{MUXER}}.
|
||||
|
||||
The option @code{-formats} of the ff* tools will display the list of
|
||||
enabled muxers.
|
||||
|
||||
A description of some of the currently available muxers follows.
|
||||
|
||||
@anchor{crc}
|
||||
@section crc
|
||||
|
||||
CRC (Cyclic Redundancy Check) testing format.
|
||||
|
||||
This muxer computes and prints the Adler-32 CRC of all the input audio
|
||||
and video frames. By default audio frames are converted to signed
|
||||
16-bit raw audio and video frames to raw video before computing the
|
||||
CRC.
|
||||
|
||||
The output of the muxer consists of a single line of the form:
|
||||
CRC=0x@var{CRC}, where @var{CRC} is a hexadecimal number 0-padded to
|
||||
8 digits containing the CRC for all the decoded input frames.
|
||||
|
||||
For example to compute the CRC of the input, and store it in the file
|
||||
@file{out.crc}:
|
||||
@example
|
||||
ffmpeg -i INPUT -f crc out.crc
|
||||
@end example
|
||||
|
||||
You can print the CRC to stdout with the command:
|
||||
@example
|
||||
ffmpeg -i INPUT -f crc -
|
||||
@end example
|
||||
|
||||
You can select the output format of each frame with @file{ffmpeg} by
|
||||
specifying the audio and video codec and format. For example to
|
||||
compute the CRC of the input audio converted to PCM unsigned 8-bit
|
||||
and the input video converted to MPEG-2 video, use the command:
|
||||
@example
|
||||
ffmpeg -i INPUT -acodec pcm_u8 -vcodec mpeg2video -f crc -
|
||||
@end example
|
||||
|
||||
See also the @ref{framecrc} muxer.
|
||||
|
||||
@anchor{framecrc}
|
||||
@section framecrc
|
||||
|
||||
Per-frame CRC (Cyclic Redundancy Check) testing format.
|
||||
|
||||
This muxer computes and prints the Adler-32 CRC for each decoded audio
|
||||
and video frame. By default audio frames are converted to signed
|
||||
16-bit raw audio and video frames to raw video before computing the
|
||||
CRC.
|
||||
|
||||
The output of the muxer consists of a line for each audio and video
|
||||
frame of the form: @var{stream_index}, @var{frame_dts},
|
||||
@var{frame_size}, 0x@var{CRC}, where @var{CRC} is a hexadecimal
|
||||
number 0-padded to 8 digits containing the CRC of the decoded frame.
|
||||
|
||||
For example to compute the CRC of each decoded frame in the input, and
|
||||
store it in the file @file{out.crc}:
|
||||
@example
|
||||
ffmpeg -i INPUT -f framecrc out.crc
|
||||
@end example
|
||||
|
||||
You can print the CRC of each decoded frame to stdout with the command:
|
||||
@example
|
||||
ffmpeg -i INPUT -f framecrc -
|
||||
@end example
|
||||
|
||||
You can select the output format of each frame with @file{ffmpeg} by
|
||||
specifying the audio and video codec and format. For example, to
|
||||
compute the CRC of each decoded input audio frame converted to PCM
|
||||
unsigned 8-bit and of each decoded input video frame converted to
|
||||
MPEG-2 video, use the command:
|
||||
@example
|
||||
ffmpeg -i INPUT -acodec pcm_u8 -vcodec mpeg2video -f framecrc -
|
||||
@end example
|
||||
|
||||
See also the @ref{crc} muxer.
|
||||
|
||||
@section image2
|
||||
|
||||
Image file muxer.
|
||||
|
||||
The image file muxer writes video frames to image files.
|
||||
|
||||
The output filenames are specified by a pattern, which can be used to
|
||||
produce sequentially numbered series of files.
|
||||
The pattern may contain the string "%d" or "%0@var{N}d", this string
|
||||
specifies the position of the characters representing a numbering in
|
||||
the filenames. If the form "%0@var{N}d" is used, the string
|
||||
representing the number in each filename is 0-padded to @var{N}
|
||||
digits. The literal character '%' can be specified in the pattern with
|
||||
the string "%%".
|
||||
|
||||
If the pattern contains "%d" or "%0@var{N}d", the first filename of
|
||||
the file list specified will contain the number 1, all the following
|
||||
numbers will be sequential.
|
||||
|
||||
The pattern may contain a suffix which is used to automatically
|
||||
determine the format of the image files to write.
|
||||
|
||||
For example the pattern "img-%03d.bmp" will specify a sequence of
|
||||
filenames of the form @file{img-001.bmp}, @file{img-002.bmp}, ...,
|
||||
@file{img-010.bmp}, etc.
|
||||
The pattern "img%%-%d.jpg" will specify a sequence of filenames of the
|
||||
form @file{img%-1.jpg}, @file{img%-2.jpg}, ..., @file{img%-10.jpg},
|
||||
etc.
|
||||
|
||||
The following example shows how to use @file{ffmpeg} for creating a
|
||||
sequence of files @file{img-001.jpeg}, @file{img-002.jpeg}, ...,
|
||||
taking one image every second from the input video:
|
||||
@example
|
||||
ffmpeg -i in.avi -r 1 -f image2 'img-%03d.jpeg'
|
||||
@end example
|
||||
|
||||
Note that with @file{ffmpeg}, if the format is not specified with the
|
||||
@code{-f} option and the output filename specifies an image file
|
||||
format, the image2 muxer is automatically selected, so the previous
|
||||
command can be written as:
|
||||
@example
|
||||
ffmpeg -i in.avi -r 1 'img-%03d.jpeg'
|
||||
@end example
|
||||
|
||||
Note also that the pattern must not necessarily contain "%d" or
|
||||
"%0@var{N}d", for example to create a single image file
|
||||
@file{img.jpeg} from the input video you can employ the command:
|
||||
@example
|
||||
ffmpeg -i in.avi -f image2 -vframes 1 img.jpeg
|
||||
@end example
|
||||
|
||||
The image muxer supports the .Y.U.V image file format. This format is
|
||||
special in that that each image frame consists of three files, for
|
||||
each of the YUV420P components. To read or write this image file format,
|
||||
specify the name of the '.Y' file. The muxer will automatically open the
|
||||
'.U' and '.V' files as required.

testing or benchmarking purposes.
|
||||
|
||||
For example to benchmark decoding with @file{ffmpeg} you can use the

For x86, mark registers that are clobbered in your asm. This means both
|
||||
general x86 registers (e.g. eax) as well as XMM registers. This last one is
|
||||
particularly important on Win64, where xmm6-15 are callee-save, and not
|
||||
restoring their contents leads to undefined results. In external asm (e.g.
|
||||
yasm), you do this by using:
|
||||
cglobal functon_name, num_args, num_regs, num_xmm_regs
|
||||
In inline asm, you specify clobbered registers at the end of your asm:
|
||||
__asm__(".." ::: "%eax").
|
||||
If gcc is not set to support sse (-msse) it will not accept xmm registers
|
||||
in the clobber list. For that we use two macros to declare the clobbers.
|
||||
XMM_CLOBBERS should be used when there are other clobbers, for example:
|
||||
__asm__(".." ::: XMM_CLOBBERS("xmm0",) "eax");
|
||||
and XMM_CLOBBERS_ONLY should be used when the only clobbers are xmm registers:
|
||||
__asm__(".." :: XMM_CLOBBERS_ONLY("xmm0"));
|
||||
|
||||
Do not expect a compiler to maintain values in your registers between separate
|
||||
(inline) asm code blocks. It is not required to. For example, this is bad:
|
||||
__asm__("movdqa %0, %%xmm7" : src);
|
||||
/* do something */
|
||||
__asm__("movdqa %%xmm7, %1" : dst);
|
||||
- first of all, you're assuming that the compiler will not use xmm7 in
|
||||
between the two asm blocks. It probably won't when you test it, but it's
|
||||
a poor assumption that will break at some point for some --cpu compiler flag
|
||||
- secondly, you didn't mark xmm7 as clobbered. If you did, the compiler would
|
||||
have restored the original value of xmm7 after the first asm block, thus
|
||||
rendering the combination of the two blocks of code invalid
|
||||
Code that depends on data in registries being untouched, should be written as
|
||||
a single __asm__() statement. Ideally, a single function contains only one
|
||||
__asm__() block.
|
||||
|
||||
Use external asm (nasm/yasm) or inline asm (__asm__()), do not use intrinsics.
|
||||
The latter requires a good optimizing compiler which gcc is not.
|
||||
|
||||
Inline asm vs. external asm
|
||||
---------------------------
|
||||
Both inline asm (__asm__("..") in a .c file, handled by a compiler such as gcc)
|
||||
and external asm (.s or .asm files, handled by an assembler such as yasm/nasm)
|
||||
are accepted in FFmpeg. Which one to use differs per specific case.
|
||||
|
||||
- if your code is intended to be inlined in a C function, inline asm is always
|
||||
better, because external asm cannot be inlined
|
||||
- if your code calls external functions, yasm is always better
|
||||
- if your code takes huge and complex structs as function arguments (e.g.
|
||||
MpegEncContext; note that this is not ideal and is discouraged if there
|
||||
are alternatives), then inline asm is always better, because predicting
|
||||
member offsets in complex structs is almost impossible. It's safest to let
|
||||
the compiler take care of that
|
||||
- in many cases, both can be used and it just depends on the preference of the
|
||||
person writing the asm. For new asm, the choice is up to you. For existing
|
||||
asm, you'll likely want to maintain whatever form it is currently in unless
|
||||
there is a good reason to change it.
|
||||
- if, for some reason, you believe that a particular chunk of existing external
|
||||
asm could be improved upon further if written in inline asm (or the other
|
||||
way around), then please make the move from external asm <-> inline asm a
|
||||
separate patch before your patches that actually improve the asm.
|
||||
Use __asm__() instead of intrinsics. The latter requires a good optimizing compiler
|
||||
which gcc is not.

Output devices are configured elements in FFmpeg which allow to write
|
||||
multimedia data to an output device attached to your system.
|
||||
|
||||
When you configure your FFmpeg build, all the supported output devices
|
||||
are enabled by default. You can list all available ones using the
|
||||
configure option "--list-outdevs".
|
||||
|
||||
You can disable all the output devices using the configure option
|
||||
"--disable-outdevs", and selectively enable an output device using the
|

option "--enable-outdev=@var{OUTDEV}", or you can disable a particular
|
||||
input device using the option "--disable-outdev=@var{OUTDEV}".

window. Only one SDL window is allowed per application, so you can
|
||||
have only one instance of this output device in an application.
|
||||
|
||||
To enable this output device you need libsdl installed on your system

@section concat
|
||||
|
||||
Physical concatenation protocol.
|
||||
|
||||
Allow to read and seek from many resource in sequence as if they were
|
||||
a unique resource.
|
||||
|
||||
A URL accepted by this protocol has the syntax:
|
||||
@example
|
||||
concat:@var{URL1}|@var{URL2}|...|@var{URLN}
|
||||
@end example
|
||||
|
||||
where @var{URL1}, @var{URL2}, ..., @var{URLN} are the urls of the
|
||||
resource to be concatenated, each one possibly specifying a distinct
|
||||
protocol.
|
||||
|
||||
For example to read a sequence of files @file{split1.mpeg},
|
||||
@file{split2.mpeg}, @file{split3.mpeg} with @file{ffplay} use the
|
||||
command:
|
||||
@example
|
||||
ffplay concat:split1.mpeg\|split2.mpeg\|split3.mpeg
|
||||
@end example
|

|
||||
Note that you may need to escape the character "|" which is special for
|

many shells.
|
||||
|
||||
@section file
|
||||
|
||||
File access protocol.
|
||||
|
||||
Allow to read from or read to a file.
|
||||
|
||||
For example to read from a file @file{input.mpeg} with @file{ffmpeg}
|
||||
use the command:
|
||||
@example
|
||||
ffmpeg -i file:input.mpeg output.mpeg

Computes the MD5 hash of the data to be written, and on close writes
|
||||
this to the designated output or stdout if none is specified. It can
|
||||
be used to test muxers without writing an actual file.
|
||||
|
||||
Some examples follow.
|
||||
@example
|
||||
# Write the MD5 hash of the encoded AVI file to the file output.avi.md5.
|

# Write the MD5 hash of the encoded AVI file to stdout.
|
||||
ffmpeg -i input.flv -f avi -y md5:
|
||||
@end example
|
||||
|
||||
Note that some formats (typically MOV) require the output protocol to
|
||||
be seekable, so they will fail with the MD5 output protocol.
|
||||
|
||||
@section pipe
|
||||
|
||||
UNIX pipe access protocol.
|
||||
|
||||
Allow to read and write from UNIX pipes.
|

||||
The accepted syntax is:
|
||||
@example
|
||||
pipe:[@var{number}]
|
||||
@end example
|
||||
|
||||
@var{number} is the number corresponding to the file descriptor of the
|
||||
pipe (e.g. 0 for stdin, 1 for stdout, 2 for stderr). If @var{number}
|
||||
is not specified, by default the stdout file descriptor will be used
|
||||
for writing, stdin for reading.
|
||||
|
||||
For example to read from stdin with @file{ffmpeg}:
|
||||
@example
|
||||
cat test.wav | ffmpeg -i pipe:0
|
||||
# ...this is the same as...
|
||||
cat test.wav | ffmpeg -i pipe:
|

ffmpeg -i test.wav -f avi pipe:1 | cat > test.avi
|
||||
# ...this is the same as...
|
||||
ffmpeg -i test.wav -f avi pipe: | cat > test.avi

The number of the TCP port to use (by default is 1935).
|
||||
|
||||
@item app
|
||||
It is the name of the application to access. It usually corresponds to

|
||||
Requires the presence of the librtmp headers and library during
|
||||
configuration. You need to explicitely configure the build with
|
||||
"--enable-librtmp". If enabled this will replace the native RTMP
|
||||
protocol.
|
||||
|
||||
This protocol provides most client functions and a few server
|
||||
functions needed to support RTMP, RTMP tunneled in HTTP (RTMPT),
|
||||
encrypted RTMP (RTMPE), RTMP over SSL/TLS (RTMPS) and tunneled
|
||||
variants of these encrypted types (RTMPTE, RTMPTS).
|
||||
|
||||
The required syntax is:

|
||||
@end example
|
||||
|
||||
where @var{rtmp_proto} is one of the strings "rtmp", "rtmpt", "rtmpe",
|
||||
"rtmps", "rtmpte", "rtmpts" corresponding to each RTMP variant, and
|
||||
@var{server}, @var{port}, @var{app} and @var{playpath} have the same
|
||||
meaning as specified for the RTMP native protocol.
|
||||
@var{options} contains a list of space-separated options of the form
|
||||
@var{key}=@var{val}.
|
||||
|
||||
See the librtmp manual page (man 3 librtmp) for more information.
|
||||
|
||||
For example, to stream a file in real-time to an RTMP server using
|
||||
@file{ffmpeg}:
|
||||
@example
|
||||
ffmpeg -re -i myfile -f flv rtmp://myserver/live/mystream
|
||||
@end example
|
||||
|

@section rtsp
|
||||
|
||||
RTSP is not technically a protocol handler in libavformat, it is a demuxer
|
||||
and muxer. The demuxer supports both normal RTSP (with data transferred
|
||||
over RTP; this is used by e.g. Apple and Microsoft) and Real-RTSP (with
|
||||
data transferred over RDT).
|
||||
|
||||
The muxer can be used to send a stream using RTSP ANNOUNCE to a server
|
||||
supporting it (currently Darwin Streaming Server and Mischa Spiegelmock's
|
||||
@uref{http://github.com/revmischa/rtsp-server, RTSP server}).
|
||||
|
||||
The required syntax for a RTSP url is:
|
||||
@example
|
||||
rtsp://@var{hostname}[:@var{port}]/@var{path}[?@var{options}]
|
||||
@end example
|
||||
|
||||
@var{options} is a @code{&}-separated list. The following options
|
||||
are supported:
|
||||
|
||||
@table @option
|
||||
|
||||
@item udp
|
||||
Use UDP as lower transport protocol.
|
||||
|
||||
@item tcp
|
||||
Use TCP (interleaving within the RTSP control channel) as lower
|
||||
transport protocol.
|
||||
|
||||
@item multicast
|
||||
Use UDP multicast as lower transport protocol.
|
||||
|
||||
@item http
|
||||
Use HTTP tunneling as lower transport protocol, which is useful for
|
||||
passing proxies.
|
||||
|
||||
@item filter_src
|
||||
Accept packets only from negotiated peer address and port.
|
||||
@end table
|
||||
|
||||
Multiple lower transport protocols may be specified, in that case they are
|
||||
tried one at a time (if the setup of one fails, the next one is tried).
|
||||
For the muxer, only the @code{tcp} and @code{udp} options are supported.
|
||||
|
||||
When receiving data over UDP, the demuxer tries to reorder received packets
|
||||
(since they may arrive out of order, or packets may get lost totally). In
|
||||
order for this to be enabled, a maximum delay must be specified in the
|
||||
@code{max_delay} field of AVFormatContext.
|
||||
|
||||
When watching multi-bitrate Real-RTSP streams with @file{ffplay}, the
|
||||
streams to display can be chosen with @code{-vst} @var{n} and
|
||||
@code{-ast} @var{n} for video and audio respectively, and can be switched
|
||||
on the fly by pressing @code{v} and @code{a}.
|
||||
|

To send a stream in realtime to a RTSP server, for others to watch:
|
||||

|
||||
|
||||
Session Announcement Protocol (RFC 2974). This is not technically a
|
||||
protocol handler in libavformat, it is a muxer and demuxer.
|
||||
It is used for signalling of RTP streams, by announcing the SDP for the
|
||||
streams regularly on a separate port.
|
||||
|
||||
@subsection Muxer
|
||||
|
||||
The syntax for a SAP url given to the muxer is:
|
||||
@example
|
||||
sap://@var{destination}[:@var{port}][?@var{options}]
|
||||
@end example
|
||||
|
||||
The RTP packets are sent to @var{destination} on port @var{port},
|
||||
or to port 5004 if no port is specified.
|
||||
@var{options} is a @code{&}-separated list. The following options
|
||||
are supported:
|
||||
|
||||
@table @option
|
||||
|
||||
@item announce_addr=@var{address}
|
||||
Specify the destination IP address for sending the announcements to.
|
||||
If omitted, the announcements are sent to the commonly used SAP
|
||||
announcement multicast address 224.2.127.254 (sap.mcast.net), or
|
||||
ff0e::2:7ffe if @var{destination} is an IPv6 address.
|
||||
|
||||
@item announce_port=@var{port}
|
||||
Specify the port to send the announcements on, defaults to
|
||||
9875 if not specified.
|
||||
|
||||
@item ttl=@var{ttl}
|
||||
Specify the time to live value for the announcements and RTP packets,
|
||||
defaults to 255.
|
||||
|
||||
@item same_port=@var{0|1}
|
||||
If set to 1, send all RTP streams on the same port pair. If zero (the
|
||||
default), all streams are sent on unique ports, with each stream on a
|
||||
port 2 numbers higher than the previous.
|
||||
VLC/Live555 requires this to be set to 1, to be able to receive the stream.
|
||||
The RTP stack in libavformat for receiving requires all streams to be sent
|
||||
on unique ports.
|
||||
@end table
|
||||
|
||||
Example command lines follow.
|
||||
|
||||
To broadcast a stream on the local subnet, for watching in VLC:
|
||||
|
||||
@example
|
||||
ffmpeg -re -i @var{input} -f sap sap://224.0.0.255?same_port=1
|
||||
@end example
|
||||
|
||||
Similarly, for watching in ffplay:
|
||||
|
||||
@example
|
||||
ffmpeg -re -i @var{input} -f sap sap://224.0.0.255
|
||||
@end example
|
||||
|
||||
And for watching in ffplay, over IPv6:
|
||||
|
||||
@example
|
||||
ffmpeg -re -i @var{input} -f sap sap://[ff0e::1:2:3:4]
|
||||
@end example
|
||||
|
||||
@subsection Demuxer
|
||||
|
||||
The syntax for a SAP url given to the demuxer is:
|
||||
@example
|
||||
sap://[@var{address}][:@var{port}]
|
||||
@end example
|
||||
|
||||
@var{address} is the multicast address to listen for announcements on,
|
||||
if omitted, the default 224.2.127.254 (sap.mcast.net) is used. @var{port}
|
||||
is the port that is listened on, 9875 if omitted.
|
||||
|
||||
The demuxers listens for announcements on the given address and port.
|
||||
Once an announcement is received, it tries to receive that particular stream.
|
||||
|
||||
Example command lines follow.
|
||||
|
||||
To play back the first stream announced on the normal SAP multicast address:
|
||||
|
||||
@example
|
||||
ffplay sap://
|
||||
@end example
|
||||
|
||||
To play back the first stream announced on one the default IPv6 SAP multicast address:
|
||||
|
||||
@example
|
||||
ffplay sap://[ff0e::2:7ffe]
|
||||
@end example
|
||||
|
||||
@section tcp
|
||||
|
||||
Trasmission Control Protocol.
|
||||
|
||||
The required syntax for a TCP url is:
|
||||
@example
|
||||
tcp://@var{hostname}:@var{port}[?@var{options}]
|
||||
@end example
|
||||
|
||||
@table @option
|
||||
|
||||
@item listen
|
||||
Listen for an incoming connection
|
||||
|
||||
@example
|
||||
ffmpeg -i @var{input} -f @var{format} tcp://@var{hostname}:@var{port}?listen
|
||||
ffplay tcp://@var{hostname}:@var{port}
|
||||
@end example
|
||||
|
||||
@end table
|
||||
|
||||
@section udp
|
||||
|
||||
User Datagram Protocol.
|
||||
|
||||
The required syntax for a UDP url is:
|
||||
@example
|
||||
udp://@var{hostname}:@var{port}[?@var{options}]
|
||||
@end example
|
||||
|
||||
@var{options} contains a list of &-seperated options of the form @var{key}=@var{val}.
|
||||
Follow the list of supported options.
|
||||
|
||||
@table @option
|
||||
|
||||
@item buffer_size=@var{size}
|
||||
set the UDP buffer size in bytes
|
||||
|
||||
@item localport=@var{port}
|
||||
override the local UDP port to bind with
|
||||
|
||||
@item pkt_size=@var{size}
|
||||
set the size in bytes of UDP packets
|
||||
|
||||
@item reuse=@var{1|0}
|
||||
explicitly allow or disallow reusing UDP sockets
|
||||
|
||||
@item ttl=@var{ttl}
|
||||
set the time to live value (for multicast only)
|
||||
|
||||
@item connect=@var{1|0}
|
||||
Initialize the UDP socket with @code{connect()}. In this case, the
|
||||
destination address can't be changed with ff_udp_set_remote_url later.
|
||||
If the destination address isn't known at the start, this option can
|
||||
be specified in ff_udp_set_remote_url, too.
|
||||
This allows finding out the source address for the packets with getsockname,
|
||||
and makes writes return with AVERROR(ECONNREFUSED) if "destination
|
||||
unreachable" is received.
|
||||
For receiving, this gives the benefit of only receiving packets from
|
||||
the specified peer address/port.
|
||||
@end table

||||
Some usage examples of the udp protocol with @file{ffmpeg} follow.

To stream over UDP to a remote endpoint:
|
||||
@example
|
||||
ffmpeg -i @var{input} -f @var{format} udp://@var{hostname}:@var{port}
|
||||
@end example
|

|

To stream in mpegts format over UDP using 188 sized UDP packets, using a large input buffer:
|
||||
@example
|
||||
ffmpeg -i @var{input} -f mpegts udp://@var{hostname}:@var{port}?pkt_size=188&buffer_size=65535

Our goal in respect to soc is and must be of course exactly one thing and

that is to improve FFmpeg, to reach this goal, code must

* conform to the svn policy and patch submission guidelines

* must improve FFmpeg somehow (faster, smaller, "better",

more codecs supported, fewer bugs, cleaner, ...)

|

for mentors and other developers to help students to reach that goal it is
|

essential that changes to their codebase are publicly visible, clean and
|

easy reviewable that again leads us to:
|

* use of a revision control system like git

* use of a revision control system like svn

* separation of cosmetic from non-cosmetic changes (this is almost entirely

ignored by mentors and students in soc 2006 which might lead to a suprise
