FFmpeg README
=============
FFmpeg is a collection of libraries and tools to process multimedia content
such as audio, video, subtitles and related metadata.
## Libraries
* `libavcodec` provides implementation of a wider range of codecs.
* `libavformat` implements streaming protocols, container formats and basic I/O access.
* `libavutil` includes hashers, decompressors and miscellaneous utility functions.
* `libavfilter` provides a mean to alter decoded Audio and Video through chain of filters.
* `libavdevice` provides an abstraction to access capture and playback devices.
* `libswresample` implements audio mixing and resampling routines.
* `libswscale` implements color conversion and scaling routines.
## Tools
* [ffmpeg](http://ffmpeg.org/ffmpeg.html) is a command line toolbox to
manipulate, convert and stream multimedia content.
* [ffplay](http://ffmpeg.org/ffplay.html) is a minimalistic multimedia player.
* [ffprobe](http://ffmpeg.org/ffprobe.html) is a simple analisys tool to inspect
multimedia content.
* Additional small tools such as `aviocat`, `ismindex` and `qt-faststart`.
## Documentation
The offline documentation is available in the **doc/** directory.
The online documentation is available in the main [website](http://ffmpeg.org)
and in the [wiki](http://trac.ffmpeg.org).
### Examples

@section AviSynth
FFmpeg can read AviSynth scripts as input. To enable support, pass
@code{--enable-avisynth} to configure. The correct headers are
included in compat/avisynth/, which allows the user to enable support
without needing to search for these headers themselves.
For Windows, supported AviSynth variants are
@url{http://avisynth.nl, AviSynth 2.5 or 2.6} for 32-bit builds and
@url{http://avs-plus.net, AviSynth+ 0.1} for 32-bit and 64-bit builds.
For Linux and OS X, the supported AviSynth variant is
@url{https://github.com/avxsynth/avxsynth, AvxSynth}.
@float NOTE
AviSynth and AvxSynth are loaded dynamically. Distributors can build FFmpeg
with @code{--enable-avisynth}, and the binaries will work regardless of the
end user having AviSynth or AvxSynth installed - they'll only need to be
installed to use AviSynth scripts (obviously).

@section avfoundation
AVFoundation input device.
AVFoundation is the currently recommended framework by Apple for streamgrabbing on OSX >= 10.7 as well as on iOS.
The older QTKit framework has been marked deprecated since OSX version 10.7.
The input filename has to be given in the following syntax:
@example
-i "[[VIDEO]:[AUDIO]]"
@end example
The first entry selects the video input while the latter selects the audio input.
The stream has to be specified by the device name or the device index as shown by the device list.
Alternatively, the video and/or audio input device can be chosen by index using the
@option{
-video_device_index <INDEX>
}
and/or
@option{
-audio_device_index <INDEX>
}
, overriding any
device name or index given in the input filename.
All available devices can be enumerated by using @option{-list_devices true}, listing
all device names and corresponding indices.
There are two device name aliases:
@table @code
@item default
Select the AVFoundation default device of the corresponding type.
@item none
Do not record the corresponding media type.
This is equivalent to specifying an empty device name or index.
@end table
@subsection Options
AVFoundation supports the following options:
@table @option
@item -list_devices <TRUE|FALSE>
If set to true, a list of all available input devices is given showing all
device names and indices.
@item -video_device_index <INDEX>
Specify the video device by its index. Overrides anything given in the input filename.
@item -audio_device_index <INDEX>
Specify the audio device by its index. Overrides anything given in the input filename.
@item -pixel_format <FORMAT>
Request the video device to use a specific pixel format.
If the specified format is not supported, a list of available formats is given
und the first one in this list is used instead. Available pixel formats are:
@code{monob, rgb555be, rgb555le, rgb565be, rgb565le, rgb24, bgr24, 0rgb, bgr0, 0bgr, rgb0,

@section gdigrab
Win32 GDI-based screen capture device.
This device allows you to capture a region of the display on Windows.
There are two options for the input filename:
@example
desktop
@end example
or
@example
title=@var{window_title}
@end example
The first option will capture the entire desktop, or a fixed region of the
desktop. The second option will instead capture the contents of a single
window, regardless of its position on the screen.
For example, to grab the entire desktop using @command{ffmpeg}:
@example
ffmpeg -f gdigrab -framerate 6 -i desktop out.mpg
@end example
Grab a 640x480 region at position @code{10,20}:
@example
ffmpeg -f gdigrab -framerate 6 -offset_x 10 -offset_y 20 -video_size vga -i desktop out.mpg
@end example
Grab the contents of the window named "Calculator"
@example
ffmpeg -f gdigrab -framerate 6 -i title=Calculator out.mpg
@end example
@subsection Options
@table @option
@item draw_mouse
Specify whether to draw the mouse pointer. Use the value @code{0} to
not draw the pointer. Default value is @code{1}.
@item framerate
Set the grabbing frame rate. Default value is @code{ntsc},
corresponding to a frame rate of @code{30000/1001}.
@item show_region
Show grabbed region on screen.
If @var{show_region} is specified with @code{1}, then the grabbing
region will be indicated on screen. With this option, it is easy to
know what is being grabbed if only a portion of the screen is grabbed.
Note that @var{show_region} is incompatible with grabbing the contents
of a single window.
For example:
@example
ffmpeg -f gdigrab -show_region 1 -framerate 6 -video_size cif -offset_x 10 -offset_y 20 -i desktop out.mpg
@end example
@item video_size
Set the video frame size. The default is to capture the full screen if @file{desktop} is selected, or the full window size if @file{title=@var{window_title}} is selected.
@item offset_x
When capturing a region with @var{video_size}, set the distance from the left edge of the screen or desktop.
Note that the offset calculation is from the top left corner of the primary monitor on Windows. If you have a monitor positioned to the left of your primary monitor, you will need to use a negative @var{offset_x} value to move the region to that monitor.
@item offset_y
When capturing a region with @var{video_size}, set the distance from the top edge of the screen or desktop.
Note that the offset calculation is from the top left corner of the primary monitor on Windows. If you have a monitor positioned above your primary monitor, you will need to use a negative @var{offset_y} value to move the region to that monitor.

The MP3 muxer writes a raw MP3 stream with the following optional features:
@itemize @bullet
@item
An ID3v2 metadata header at the beginning (enabled by default). Versions 2.3 and
2.4 are supported, the @code{id3v2_version} private option controls which one is
used (3 or 4). Setting @code{id3v2_version} to 0 disables the ID3v2 header
completely.
The MP3 muxer writes a raw MP3 stream with an ID3v2 header at the beginning and
optionally an ID3v1 tag at the end. ID3v2.3 and ID3v2.4 are supported, the
@code{id3v2_version} option controls which one is used. Setting
@code{id3v2_version} to 0 will disable the ID3v2 header completely. The legacy
ID3v1 tag is not written by default, but may be enabled with the
@code{write_id3v1} option.
The muxer supports writing attached pictures (APIC frames) to the ID3v2 header.
The pictures are supplied to the muxer in form of a video stream with a single
packet. There can be any number of those streams, each will correspond to a
single APIC frame. The stream metadata tags @var{title} and @var{comment} map
to APIC @var{description} and @var{picture type} respectively. See
The muxer may also write a Xing frame at the beginning, which contains the
number of frames in the file. It is useful for computing duration of VBR files.
The Xing frame is written if the output stream is seekable and if the
@code{write_xing} option is set to 1 (the default).
The muxer supports writing ID3v2 attached pictures (APIC frames). The pictures
are supplied to the muxer in form of a video stream with a single packet. There
can be any number of those streams, each will correspond to a single APIC frame.
The stream metadata tags @var{title} and @var{comment} map to APIC
@var{description} and @var{picture type} respectively. See
@url{http://id3.org/id3v2.4.0-frames} for allowed picture types.
Note that the APIC frames must be written at the beginning, so the muxer will
buffer the audio frames until it gets all the pictures. It is therefore advised
to provide the pictures as soon as possible to avoid excessive buffering.
@item
A Xing/LAME frame right after the ID3v2 header (if present). It is enabled by
default, but will be written only if the output is seekable. The
@code{write_xing} private option can be used to disable it. The frame contains
various information that may be useful to the decoder, like the audio duration
or encoder delay.
@item
A legacy ID3v1 tag at the end of the file (disabled by default). It may be
enabled with the @code{write_id3v1} private option, but as its capabilities are
very limited, its usage is not recommended.

This document is a tutorial/initiation for writing simple filters in
libavfilter.
Foreword: just like everything else in FFmpeg, libavfilter is monolithic, which
means that it is highly recommended that you submit your filters to the FFmpeg
development mailing-list and make sure it is applied. Otherwise, your filter is
likely to have a very short lifetime due to more a less regular internal API
changes, and a limited distribution, review, and testing.
Bootstrap
=========
Let's say you want to write a new simple video filter called "foobar" which
takes one frame in input, changes the pixels in whatever fashion you fancy, and
outputs the modified frame. The most simple way of doing this is to take a
similar filter. We'll pick edgedetect, but any other should do. You can look
for others using the `./ffmpeg -v 0 -filters|grep ' V->V '` command.
- sed 's/edgedetect/foobar/g;s/EdgeDetect/Foobar/g' libavfilter/vf_edgedetect.c > libavfilter/vf_foobar.c
- edit libavfilter/Makefile, and add an entry for "foobar" following the
pattern of the other filters.
- edit libavfilter/allfilters.c, and add an entry for "foobar" following the
pattern of the other filters.
- ./configure ...
- make -j<whatever> ffmpeg
- ./ffmpeg -i http://samples.ffmpeg.org/image-samples/lena.pnm -vf foobar foobar.png
Note here: you can obviously use a random local image instead of a remote URL.
If everything went right, you should get a foobar.png with Lena edge-detected.
That's it, your new playground is ready.
Some little details about what's going on:
libavfilter/allfilters.c:avfilter_register_all() is called at runtime to create
a list of the available filters, but it's important to know that this file is
also parsed by the configure script, which in turn will define variables for
the build system and the C:
--- after running configure ---
$ grep FOOBAR config.mak
CONFIG_FOOBAR_FILTER=yes
$ grep FOOBAR config.h
#define CONFIG_FOOBAR_FILTER 1
CONFIG_FOOBAR_FILTER=yes from the config.mak is later used to enable the filter in
libavfilter/Makefile and CONFIG_FOOBAR_FILTER=1 from the config.h will be used
for registering the filter in libavfilter/allfilters.c.
Filter code layout
==================
You now need some theory about the general code layout of a filter. Open your
libavfilter/vf_foobar.c. This section will detail the important parts of the
code you need to understand before messing with it.
Copyright
---------
First chunk is the copyright. Most filters are LGPL, and we are assuming
vf_foobar is as well. We are also assuming vf_foobar is not an edge detector
filter, so you can update the boilerplate with your credits.
Doxy
----
Next chunk is the Doxygen about the file. See http://ffmpeg.org/doxygen/trunk/.
Detail here what the filter is, does, and add some references if you feel like
it.
Context
-------
Skip the headers and scroll down to the definition of FoobarContext. This is
your local state context. It is already filled with 0 when you get it so do not
worry about uninitialized read into this context. This is where you put every
"global" information you need, typically the variable storing the user options.
You'll notice the first field "const AVClass *class"; it's the only field you
need to keep assuming you have a context. There are some magic you don't care
about around this field, just let it be (in first position) for now.
Options
-------
Then comes the options array. This is what will define the user accessible
options. For example, -vf foobar=mode=colormix:high=0.4:low=0.1. Most options
have the following pattern:
name, description, offset, type, default value, minimum value, maximum value, flags
- name is the option name, keep it simple, lowercase
- description are short, in lowercase, without period, and describe what they
do, for example "set the foo of the bar"
- offset is the offset of the field in your local context, see the OFFSET()
macro; the option parser will use that information to fill the fields
according to the user input
- type is any of AV_OPT_TYPE_* defined in libavutil/opt.h
- default value is an union where you pick the appropriate type; "{.dbl=0.3}",
"{.i64=0x234}", "{.str=NULL}", ...
- min and max values define the range of available values, inclusive
- flags are AVOption generic flags. See AV_OPT_FLAG_* definitions
In doubt, just look at the other AVOption definitions all around the codebase,
there are tons of examples.
Class
-----
AVFILTER_DEFINE_CLASS(foobar) will define a unique foobar_class with some kind
of signature referencing the options, etc. which will be referenced in the
definition of the AVFilter.
Filter definition
-----------------
At the end of the file, you will find foobar_inputs, foobar_outputs and
the AVFilter ff_vf_foobar. Don't forget to update the AVFilter.description with
a description of what the filter does, starting with a capitalized letter and
ending with a period. You'd better drop the AVFilter.flags entry for now, and
re-add them later depending on the capabilities of your filter.
Callbacks
---------
Let's now study the common callbacks. Before going into details, note that all
these callbacks are explained in details in libavfilter/avfilter.h, so in
doubt, refer to the doxy in that file.
init()
~~~~~~
First one to be called is init(). It's flagged as cold because not called
often. Look for "cold" on
http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html for more
information.
As the name suggests, init() is where you eventually initialize and allocate
your buffers, pre-compute your data, etc. Note that at this point, your local
context already has the user options initialized, but you still haven't any
clue about the kind of data input you will get, so this function is often
mainly used to sanitize the user options.
Some init()s will also define the number of inputs or outputs dynamically
according to the user options. A good example of this is the split filter, but
we won't cover this here since vf_foobar is just a simple 1:1 filter.
uninit()
~~~~~~~~
Similarly, there is the uninit() callback, doing what the name suggest. Free
everything you allocated here.
query_formats()
~~~~~~~~~~~~~~~
This is following the init() and is used for the format negotiation, basically
where you say what pixel format(s) (gray, rgb 32, yuv 4:2:0, ...) you accept
for your inputs, and what you can output. All pixel formats are defined in
libavutil/pixfmt.h. If you don't change the pixel format between the input and
the output, you just have to define a pixel formats array and call
ff_set_common_formats(). For more complex negotiation, you can refer to other
filters such as vf_scale.
config_props()
~~~~~~~~~~~~~~
This callback is not necessary, but you will probably have one or more
config_props() anyway. It's not a callback for the filter itself but for its
inputs or outputs (they're called "pads" - AVFilterPad - in libavfilter's
lexicon).
Inside the input config_props(), you are at a point where you know which pixel
format has been picked after query_formats(), and more information such as the
video width and height (inlink->{w,h}). So if you need to update your internal
context state depending on your input you can do it here. In edgedetect you can
see that this callback is used to allocate buffers depending on these
information. They will be destroyed in uninit().
Inside the output config_props(), you can define what you want to change in the
output. Typically, if your filter is going to double the size of the video, you
will update outlink->w and outlink->h.
filter_frame()
~~~~~~~~~~~~~~
This is the callback you are waiting from the beginning: it is where you
process the received frames. Along with the frame, you get the input link from
where the frame comes from.
static int filter_frame(AVFilterLink *inlink, AVFrame *in) { ... }
You can get the filter context through that input link:
AVFilterContext *ctx = inlink->dst;
Then access your internal state context:
FoobarContext *foobar = ctx->priv;
And also the output link where you will send your frame when you are done:
AVFilterLink *outlink = ctx->outputs[0];
Here, we are picking the first output. You can have several, but in our case we
only have one since we are in a 1:1 input-output situation.
If you want to define a simple pass-through filter, you can just do:
return ff_filter_frame(outlink, in);
But of course, you probably want to change the data of that frame.
This can be done by accessing frame->data[] and frame->linesize[]. Important
note here: the width does NOT match the linesize. The linesize is always
greater or equal to the width. The padding created should not be changed or
even read. Typically, keep in mind that a previous filter in your chain might
have altered the frame dimension but not the linesize. Imagine a crop filter
that halves the video size: the linesizes won't be changed, just the width.
<-------------- linesize ------------------------>
+-------------------------------+----------------+ ^
| | | |
| | | |
| picture | padding | | height
| | | |
| | | |
+-------------------------------+----------------+ v
<----------- width ------------->
Before modifying the "in" frame, you have to make sure it is writable, or get a
new one. Multiple scenarios are possible here depending on the kind of
processing you are doing.
Let's say you want to change one pixel depending on multiple pixels (typically
the surrounding ones) of the input. In that case, you can't do an in-place
processing of the input so you will need to allocate a new frame, with the same
properties as the input one, and send that new frame to the next filter:
AVFrame *out = ff_get_video_buffer(outlink, outlink->w, outlink->h);
if (!out) {
av_frame_free(&in);
return AVERROR(ENOMEM);
}
av_frame_copy_props(out, in);
// out->data[...] = foobar(in->data[...])
av_frame_free(&in);
return ff_filter_frame(outlink, out);
In-place processing
~~~~~~~~~~~~~~~~~~~
If you can just alter the input frame, you probably just want to do that
instead:
av_frame_make_writable(in);
// in->data[...] = foobar(in->data[...])
return ff_filter_frame(outlink, in);
You may wonder why a frame might not be writable. The answer is that for
example a previous filter might still own the frame data: imagine a filter
prior to yours in the filtergraph that needs to cache the frame. You must not
alter that frame, otherwise it will make that previous filter buggy. This is
where av_frame_make_writable() helps (it won't have any effect if the frame
already is writable).
The problem with using av_frame_make_writable() is that in the worst case it
will copy the whole input frame before you change it all over again with your
filter: if the frame is not writable, av_frame_make_writable() will allocate
new buffers, and copy the input frame data. You don't want that, and you can
avoid it by just allocating a new buffer if necessary, and process from in to
out in your filter, saving the memcpy. Generally, this is done following this
scheme:
int direct = 0;
AVFrame *out;
if (av_frame_is_writable(in)) {
direct = 1;
out = in;
} else {
out = ff_get_video_buffer(outlink, outlink->w, outlink->h);
if (!out) {
av_frame_free(&in);
return AVERROR(ENOMEM);
}
av_frame_copy_props(out, in);
}
// out->data[...] = foobar(in->data[...])
if (!direct)
av_frame_free(&in);
return ff_filter_frame(outlink, out);
Of course, this will only work if you can do in-place processing. To test if
your filter handles well the permissions, you can use the perms filter. For
example with:
-vf perms=random,foobar
Make sure no automatic pixel conversion is inserted between perms and foobar,
otherwise the frames permissions might change again and the test will be
meaningless: add av_log(0,0,"direct=%d\n",direct) in your code to check that.
You can avoid the issue with something like:
-vf format=rgb24,perms=random,foobar
...assuming your filter accepts rgb24 of course. This will make sure the
necessary conversion is inserted before the perms filter.
Timeline
~~~~~~~~
Adding timeline support
(http://ffmpeg.org/ffmpeg-filters.html#Timeline-editing) is often an easy
feature to add. In the most simple case, you just have to add
AVFILTER_FLAG_SUPPORT_TIMELINE_GENERIC to the AVFilter.flags. You can typically
do this when your filter does not need to save the previous context frames, or
basically if your filter just alter whatever goes in and doesn't need
previous/future information. See for instance commit 86cb986ce that adds
timeline support to the fieldorder filter.
In some cases, you might need to reset your context somehow. This is handled by
the AVFILTER_FLAG_SUPPORT_TIMELINE_INTERNAL flag which is used if the filter
must not process the frames but still wants to keep track of the frames going
through (to keep them in cache for when it's enabled again). See for example
commit 69d72140a that adds timeline support to the phase filter.
Threading
~~~~~~~~~
libavfilter does not yet support frame threading, but you can add slice
threading to your filters.
Let's say the foobar filter has the following frame processing function:
dst = out->data[0];
src = in ->data[0];
for (y = 0; y < inlink->h; y++) {
for (x = 0; x < inlink->w; x++)
dst[x] = foobar(src[x]);
dst += out->linesize[0];
src += in ->linesize[0];
}
The first thing is to make this function work into slices. The new code will
look like this:
for (y = slice_start; y < slice_end; y++) {
for (x = 0; x < inlink->w; x++)
dst[x] = foobar(src[x]);
dst += out->linesize[0];
src += in ->linesize[0];
}
The source and destination pointers, and slice_start/slice_end will be defined
according to the number of jobs. Generally, it looks like this:
const int slice_start = (in->height * jobnr ) / nb_jobs;
const int slice_end = (in->height * (jobnr+1)) / nb_jobs;
uint8_t *dst = out->data[0] + slice_start * out->linesize[0];
const uint8_t *src = in->data[0] + slice_start * in->linesize[0];
This new code will be isolated in a new filter_slice():
static int filter_slice(AVFilterContext *ctx, void *arg, int jobnr, int nb_jobs) { ... }
Note that we need our input and output frame to define slice_{start,end} and
dst/src, which are not available in that callback. They will be transmitted
through the opaque void *arg. You have to define a structure which contains
everything you need:
typedef struct ThreadData {
AVFrame *in, *out;
} ThreadData;
If you need some more information from your local context, put them here.
In you filter_slice function, you access it like that:
const ThreadData *td = arg;
Then in your filter_frame() callback, you need to call the threading
distributor with something like this:
ThreadData td;
// ...
td.in = in;
td.out = out;
ctx->internal->execute(ctx, filter_slice, &td, NULL, FFMIN(outlink->h, ctx->graph->nb_threads));
// ...
return ff_filter_frame(outlink, out);
Last step is to add AVFILTER_FLAG_SLICE_THREADS flag to AVFilter.flags.
For more example of slice threading additions, you can try to run git log -p
--grep 'slice threading' libavfilter/
Finalization
~~~~~~~~~~~~
When your awesome filter is finished, you have a few more steps before you're
done:
- write its documentation in doc/filters.texi, and test the output with make
doc/ffmpeg-filters.html.
- add a FATE test, generally by adding an entry in
tests/fate/filter-video.mak, add running make fate-filter-foobar GEN=1 to
generate the data.
- add an entry in the Changelog
- edit libavfilter/version.h and increase LIBAVFILTER_VERSION_MINOR by one
(and reset LIBAVFILTER_VERSION_MICRO to 100)
- git add ... && git commit -m "avfilter: add foobar filter." && git format-patch -1
When all of this is done, you can submit your patch to the ffmpeg-devel
mailing-list for review. If you need any help, feel free to come on our IRC
channel, #ffmpeg-devel on irc.freenode.net.
