2013-02-26Remove unnecessary dsputil.h #includesDiego Biurrun
2012-12-23huffyuv: split encoder and decoder into separate files.Anton Khirnov
2012-12-05lavc: fix decode_frame() third parameter semantics for video decodersAnton Khirnov
It's got_frame, not data size
2012-10-08Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormatAnton Khirnov
2012-10-01Remove some silly disabled code.Diego Biurrun
2012-08-28huffman: add ff_huff_gen_len_tableMichael Niedermayer
The function will be used by utvideo as well. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
2012-08-27huffyuv: update to current coding styleLuca Barbato
2012-08-07Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov
2012-04-06cosmetics: Align codec declarationsMartin Storsjö
Also break some long lines, remove codec function placeholder comments and add spaces in sample/pixel format lists. Signed-off-by: Martin Storsjö <martin@martin.st>
2012-03-08huffyuv: add padding to classic (v1) huffman tables.Ronald S. Bultje
We slightly overread the input buffer, so we require padding at the end of the buffer, as is documented in the get_bits API. Without padding, we'll read uninitialized data or beyond the end of the .rodata, which may crash. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
2012-03-05Replace computations of remaining bits with calls to get_bits_left().Alex Converse
2012-03-01huffyuv: do not abort on unknown pix_fmt; instead, return an error.Ronald S. Bultje
Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
2012-02-20huffyuv: switch to encode2().Anton Khirnov
2012-02-18huffyuv: error out on bit overrun.Ronald S. Bultje
On EOF, get_bits() will continuously return 0, causing an infinite loop. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
2012-02-16dsputil: Add ff_ prefix to the dsputil*_init* functionsMartin Storsjö
Signed-off-by: Martin Storsjö <martin@martin.st>
2012-02-16vlc/rl: Add ff_ prefix to the nonstatic symbolsMartin Storsjö
Signed-off-by: Martin Storsjö <martin@martin.st>
2011-12-03avcodec: change number of plane pointers from 4 to 8 at next major bump.Justin Ruggles
Add AV_NUM_DATA_POINTERS to simplify the bump transition. This will allow for supporting more planar audio channels without having to allocate separate pointer arrays.
2011-07-29lavc: use designated initialisers for all codecs.Anton Khirnov
It's more readable and less prone to breakage.
2011-05-02Replace deprecated FF_*_TYPE symbols with AV_PICTURE_TYPE_*.Stefano Sabatini
Signed-off-by: Diego Biurrun <diego@biurrun.de>
2011-04-29Remove some disabled printf debug cruft.Diego Biurrun
2011-03-19Replace FFmpeg with Libav in licence headersMans Rullgard
Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-03-01huffyuv: Add multithreading supportAlexander Strange
Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
2011-01-26Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò
None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>

Originally committed as revision 23784 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun
Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-17Add const to some pointer parameters.Michael Kaufmann
Patch by Michael Kaufmann, hallo michael-kaufmann ch Originally committed as revision 22900 to svn://svn.ffmpeg.org/ffmpeg/trunk

2010-03-31Define AVMediaType enum, and use it instead of enum CodecType, whichStefano Sabatini
is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-14Implement alpha channel decoding for BGR HuffYUV.Alexander Strange
Since BGR24 is decoded as BGR32, fill its alpha channel with 255 using the appropriate predictors. Originally committed as revision 21211 to svn://svn.ffmpeg.org/ffmpeg/trunk

2009-09-06Mark all pix_fmts and supported_framerates compound literals as const.Reimar Döffinger

Fixes issue1237. Originally committed as revision 19322 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-05-23Fix passing of unaligned addresses to dsputil diff_bytes() byJeff Downs
changeing calls to sub_left_prediction such that the source frame data pointers are no longer offset to skip the initial elements. This keeps them properly aligned for the subsequent call to diff_bytes. Changes encoding offset to compensate. Mailing list thread: https://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2009-May/069952.html Originally committed as revision 18919 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-05-23Add offset argument to encode_422_bitstream() to control whereJeff Downs
in the source data array to start encoding. Change all calls to pass zero for this new argument for equivalent behavior. This is a restructure to support a forthcoming bug fix. Originally committed as revision 18918 to svn://svn.ffmpeg.org/ffmpeg/trunk

Originally committed as revision 18494 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-04-12Add a av_fast_malloc function and replace several uses of av_fast_realloc,Reimar Döffinger

2009-04-12Split bitstream.h, put the bitstream writer stuff in the new fileStefano Sabatini
put_bits.h. Originally committed as revision 18461 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-04-07Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes anThilo Borgmann
AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows passing of packet-specific flags from demuxer to decoder, such as the keyframe flag, which appears necessary to playback corePNG P-frames. Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread "Google Summer of Code participation" on the mailinglist.
