avpicture_get_size() returns the size of buffer required for avpicture_layout.
For pseudo-paletted formats (gray8...) this size does not include the palette.
However, avpicture_layout doesn't know this and still writes the palette. Consequently,
avpicture_layout writes passed the length of the buffer. This fixes it
by fixing avpicture_layout so that it doesn't write the palette for these formats.

This allows skipping past unsupported RTCP packet types, as

When converting RGB format to RGB format with the same bits per sample,
unscaled path performs conversion on the whole buffer at once. For
non-multiple-of-16 BGR24 to RGB24 conversion it means that padding at the
end of line will be converted too. Since it may be of arbitrary length
(e.g. 8 bytes), operating on the whole buffer produces obviously wrong
results.

Previously, "dar" and "a" were documented like "input display aspect
ratio", but their actual value was "in_w/in_h".
In order to avoid to break scripts which rely on the "a" variable, the
patch keeps the same semantics but fixes the corresponding docs, and
fixes the semantics of the recently added "dar" variable, which
now correctly expresses the input Display Aspect Ratio value as
"(inw_w/in_h)*sar".

Inspection of compiled code shows gcc handles these fine on its own.
Benchmarking also shows no measurable speed difference.
Removing the remaining cases in get_cabac_bypass_sign_x86() does
cause more substantial changes to the compiled code with uncertain

The current checks on MMCO parameters prohibits a "max long term frame index

"SAR" (Sample Aspect Ratio) is globally preferred over "PAR" (Pixel
Aspect Ratio), although the two terms share the same semantics.
For example the corresponding AVStream field is called
sample_aspect_ratio, and libavfilter has a filter named setsar.
Therefore prefer the term "SAR" over "PAR" in the
libavformat/utils.c:dump_stream_format() and avcodec_string() output
for avoiding confusion.
Previously the string for AV_CH_LAYOUT_5POINT{0,1}_BACK was the same
of the string for AV_CH_LAYOUT_5POINT{0,1}.
This is required for discerning the two channel layouts, given a
channel layout string.

Since IDCT transforming 32-bit input to 8-bit output is unusual and unpractical

Avoid the use of the brittle/inconsistent information in
PixFmtInfo.depth, and implement a possibly more robust logic which
exposes the information in pixdesc.
Also allow the removal of PixFmtInfo.depth, since this is the only use
of it.
The upcoming gcc 4.7 has more advanced constant propagation
resulting some inline asm operands becoming constants and thus
emitted as literals, sometimes in contexts where this results
in invalid instructions.
This patch changes the constraints of the relevant operands
to "rm" thus forcing a valid type. While obviously suboptimal,
this is what older gcc versions already did, and there is no
change to the code generated with these.

The field is only used for checking if a format is YUV planar
and if the format is paletted.
This patch replaces the current is_planar_yuv() code with a function
which uses the pixdesc information. The new implementation is less
efficient, but this should not be an issue as the functions which use
it (av_picture_crop/pad()) are deprecated and currently never used in
the codebase.
Prefer data-driven over procedural logic in avg_bits_per_pixel(),
simplify and improve robustness, as it is easy to miss a function
update when a new format is added.

Shallow clones (--depth X) lack the N tag used to compute

Snapshots from gitweb do not have git information at all,
but they have the short git hash in the directory name:
append it to the release number.
High bitdepth H.264 needs 32-bit transform coefficients, whereas
dnxhd does not. This creates a conflict with the templated

Mpegvideo would free frames as soon as they're not the next or prev
picture. This is fine for a single-threading model, but fails miserably
in a system where pictures can be referenced (as e.g. last/prev pic)
in other threads. Keeping track of ownership of pictures keeps image
references (e.g. motion vectors, or the reference of a motion vector)
alive as long as the picture data itself is alive.
This also happens to fix make THREADS=[3-16] fate-vsynth[12]-error.

ptrdiff_t can be 4 bytes, which leads to the next element being 4-byte

alignment forces equal offset of dither16/32 on x86-32 and x86-64.

Since avfilter_graph_parse() creates the "[in]" inout for the first
unlabelled input pad, it is expected that it will create an "[out]"
inout for last unlabelled output pad, even in the case where it cannot

This change removes the check on the existence of an open input pad
named "out", so it simplifies the checked condition while implementing

ogg_save() copies streams[], but doesn't keep track of free()'ed
struct members. Thus, if in between a call to ogg_save() and

Set the frame size when decoding DTS audio.
This has the side effect of fixing the computation of timestamps for DTS-HD in compute_pkt_fields. Since frame_size is
not currently set, the duration of a frame is being guessed based on the streams bitrate. But for DTS-HD, the bitrate
currently used is the rate of the DTS core which is much different than the whole DTS-HD stream and leads to a wildly
inaccurate frame duration estimate.

The value for inpic->data[plane] with plane >=4 is undefined, and it

exiting the loop when plane reaches the value 4.
Fix crash (occurring for example with: format=rgba,lut).
Before this, almost all module groups have been used for grouping functions
and fields in structures semantically. This causes them to not appear
properly in the file documentation and needlessly clutters up the "Modules"
index.
Additionally, this commit streamlines some spelling and appearances.
The PTS for captured audio was measured using snd_pcm_htimestamp.
snd_pcm_htimestamp hangs when the input is a dsnoop plugin.
Furthermore, at some point, snd_pcm_htimestamp started returning monotonic
timestamps rather than wall clock timestamps, in most but not all
situations.
Monotonic timestamps are fine, but ffmpeg uses wall clock timestamps
everywhere else, and we have no API to inform the user which kind of
timestamps it is.
A separate snd_pcm_htimestamp is only slightly less accurate than
snd_pcm_htimestamp: the standard deviation for the difference between two
consecutive timestamps is (on my hardware):
- ~13 µs with snd_pcm_htimestamp;
- ~35 µs with av_gettime;
- ~5 µs with av_gettime and a timefilter.
av_open_input_stream used to allow this, even though it makes no sense.
Make it just print a warning instead of failing, thus restoring
compatibility.
Note that avformat_open_input() will still reject this combination.

In adjust_frame_information(), msc is incremented for each sfb in each
sub-window then compared against max_sfb which is for a single sub-window.
This resulted in frames using EIGHT_SHORT_SEQUENCE where the first few
sub-windows increment msc to a value that results in ms_mode == 2. Even
though only some of the bands are actually using Mid/Side.
ogg_save() copies streams[], but doesn't keep track of free()'ed
struct members. Thus, if in between a call to ogg_save() and
ogg_restore(), streams[].private was free()'ed, this would result
in a double free -> crash, which happened when e.g. playing small

This fixes a problem for fate-related .mak files in the tests and tests/fate

In commit bebe72f4a0, the enum AV_PICTURE_TYPE_* was introduced. There are still places in the code where pict_type is used as an integer and there is a case where "pict_type = 0" with the explanation "let ffmpeg decide what to do". The new enum does not know a value of 0 and C++ will fail if compiling such programs anyway as it is refered as an int (and you cannot patch them properly).
Remove unused variables "flags" and "dstFormat" in yuv2packed1,
merge source rows per plane for yuv2packed[12], and make every
source argument int16_t (some where invalidly set to uint16_t).

Michael's TODO list: (unordered) (if anyone wanna help with sth, just ask)
-------------------
- optimize H264 CABAC
- more optimizations
- simper rate control
Philip'a TODO list: (alphabetically ordered) (please help)
------------------
- Add a multi-ffm filetype so that feeds can be recorded into multiple files rather
than one big file.
- Authenticated users support -- where the authentication is in the URL
- Change ASF files so that the embedded timestamp in the frames is right rather
than being an offset from the start of the stream
- Make ffm files more resilient to changes in the codec structures so that you
can play old ffm files.
Baptiste's TODO list:
-----------------
- mov edit list support (AVEditList)
- YUV 10 bit per component support "2vuy"
- mxf muxer
- mpeg2 non linear quantizer
unassigned TODO: (unordered)
---------------
- use AVFrame for audio codecs too
- rework aviobuf.c buffering strategy and fix url_fskip
- generate optimal huffman tables for mjpeg encoding
- fix ffserver regression tests
- support xvids motion estimation
- support x264s motion estimation
- support x264s rate control
- SNOW: non translational motion compensation
- SNOW: more optimal quantization
- SNOW: 4x4 block support
- SNOW: 1/8 pel motion compensation support
- SNOW: iterative motion estimation based on subsampled images
- SNOW: try B frames and MCTF and see how their PSNR/bitrate/complexity behaves
- SNOW: try to use the wavelet transformed MC-ed reference frame as context for the entropy coder
- SNOW: think about/analyize how to make snow use multiple cpus/threads
- SNOW: finish spec
- FLAC: lossy encoding (viterbi and naive scalar quantization)
- libavfilter
- JPEG2000 decoder & encoder
- MPEG4 GMC encoding support
- macroblock based pixel format (better cache locality, somewhat complex, one paper claimed it faster for high res)
- regression tests for codecs which do not have an encoder (I+P-frame bitstream in the 'master' branch)
- add support for using mplayers video filters to ffmpeg
- H264 encoder
- per MB ratecontrol (so VCD and such do work better)
- write a script which iteratively changes all functions between always_inline and noinline and benchmarks the result to find the best set of inlined functions
- convert all the non SIMD asm into small asm vs. C testcases and submit them to the gcc devels so they can improve gcc
- generic audio mixing API
- extract PES packetizer from PS muxer and use it for new TS muxer
- implement automatic AVBistreamFilter activation
- make cabac encoder use bytestream (see http://trac.videolan.org/x264/changeset/?format=diff&new=651)
- merge imdct and windowing, the current code does considerable amounts of redundant work
