2012-02-10h264: disallow constrained intra prediction modes for luma.Ronald S. Bultje
Conversion of the luma intra prediction mode to one of the constrained ("alzheimer") ones can happen by crafting special bitstreams, causing a crash because we'll call a NULL function pointer for 16x16 block intra prediction, since constrained intra prediction functions are only implemented for chroma (8x8 blocks).

2011-07-29lavc: use designated initialisers for all codecs.Anton Khirnov
It's more readable and less prone to breakage.
2011-07-11Eliminate FF_COMMON_FRAME macro.Diego Biurrun
FF_COMMON_FRAME holds the contents of the AVFrame structure and is also copied to struct Picture. Replace by an embedded AVFrame structure in struct Picture.
2011-07-04H.264: faster write_back_*Jason Garrett-Glaser
Avoid aliasing, unroll loops, and inline more functions.
2011-06-14Fix SVQ3 after adding 4:4:4 H.264 supportJason Garrett-Glaser
2011-06-14Roll back 4:4:4 H.264 for nowJason Garrett-Glaser
Needs some ARM/PPC asm modifications.

2011-05-21svq3: Do initialization after parsing the extradataRonald S. Bultje
If done before, some parameters aren't known yet. With svq3/rtp, initializing before some parameters are known can lead to calling av_malloc(0), which on OS X currently returns broken pointers.

2011-04-02lavc: mark hurry_up for removal on next major bumpAnton Khirnov
It has been deprecated for about five years, skip_idct/skip_frame should be used instead.

2011-01-29Move ff_emulated_edge_mc() into DSPContext.Ronald S. Bultje
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>
2011-01-21Revert 2a1f431d38ea9c05abb215d70c7dc09cdb6888ab, it broke H264 lossless.Ronald S. Bultje
2011-01-15H.264/SVQ3: make chroma DC work the same way as luma DCJason Garrett-Glaser
No speed improvement, but necessary for some future stuff. Also opens up the possibility of asm chroma dc idct/dequant. Originally committed as revision 26349 to svn://svn.ffmpeg.org/ffmpeg/trunk
2011-01-15Port SVQ3 to use the new mb_luma_dc method of storing luma DC coefficients.Jason Garrett-Glaser
Doesn't help speed as there isn't an asm implementation yet, but consistency is a good thing. Originally committed as revision 26348 to svn://svn.ffmpeg.org/ffmpeg/trunk
2011-01-15Fix SVQ3Jason Garrett-Glaser
Regression in r26336-7. Originally committed as revision 26341 to svn://svn.ffmpeg.org/ffmpeg/trunk
2011-01-15H.264: split luma dc idct out and implement MMX/SSE2 versionsJason Garrett-Glaser
About 2.5x the speed. NOTE: the way that the asm code handles large qmuls is a bit suboptimal. If x264-style dequant was used (separate shift and qmul values), it might be possible to get some extra speed. Originally committed as revision 26336 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-12-15SVQ3: Allow decoding if thread_count is > 1Alexander Strange
svq3 still doesn't support multithreading, but it's simpler for clients if they can enable threading for all codecs by default. Originally committed as revision 26015 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-06-16Fix svq3 watermark log uncompress on 64bit, probably fixes issue 1263Baptiste Coudurier
Originally committed as revision 23620 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
2010-03-31Define 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
2010-02-25svq3 now in working condition, at least vissually, ill let fate tell usMichael Niedermayer

2010-02-25fix compilation, sorry ive not checked cvslog for a while :(((Michael Niedermayer
svq3 decoder does not work yet though but i didnt want to keep compilation broken longer Originally committed as revision 22060 to svn://svn.ffmpeg.org/ffmpeg/trunk

2010-01-13Split motion vector prediction off h264.c/h.Michael Niedermayer
Originally committed as revision 21174 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-13Move check_intra4x4_pred_mode() back from h264.h to h264.c, the function is justMichael Niedermayer
called once per MB in worst case and doesnt seem to benefit from static inline. Actually the code might be a hair faster now (0.1% according to my benchmark but this could be random noise) Originally committed as revision 21173 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-12Get rid of #include "svq3.c"Michael Niedermayer
functions called more than per mb are moved into the header, scan8 is also as it must be known at compiletime. The code after this patch duplicates h264data.h, this has been done to minimize the changes in this step and allow more fine grained benchmarking. Speedwise this is 1% faster on my pentium dual core with diegos cursed cathedral sample. Originally committed as revision 21157 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-12-12SVQ3 : Set avctx->pix_fmt correctly during decoder initialisation.Jai Menon

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

Originally committed as revision 18988 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. Originally committed as revision 18351 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-03-01SVQ3: Fix decoding with A32_BITSTREAM_READERMåns Rullgård
svq3_decode_slice_header() modifies the buffer used by the bitstream reader. Some of the bitstream readers cache a few bytes of data, which must be flushed after such a modification. Calling skip_bits_long(gb, 0) achieves this. Originally committed as revision 17680 to svn://svn.ffmpeg.org/ffmpeg/trunk
