Martin Storsjö	00c3b67b8a	cosmetics: Align codec declarations 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>	13 years ago
Michael Niedermayer	96df29c318	svq3: Fix pointer type mismatch warning. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	28a613b09b	h264: dont mess with chroma planes for grayscale h264. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Ronald S. Bultje	11b940a1a8	svq3: protect against negative quantizers. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	c23acbaed4	Don't use ff_cropTbl[] for IDCT. Results of IDCT can by far outreach the range of ff_cropTbl[], leading to overreads and potentially crashes. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Diego Biurrun	324deaa268	Replace AVFrame pointer type punning by proper struct member assignments.	13 years ago
Michael Niedermayer	436f866f92	svq3dec: fix overread of the cliping table. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Martin Storsjö	efd29844eb	mpegvideo: Add ff_ prefix to nonstatic functions Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Alex Converse	9e1db721c4	svq3: Prevent illegal reads while parsing extradata. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind	13 years ago
Ronald S. Bultje	45b7bd7c53	h264: disallow constrained intra prediction modes for luma. 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). Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Laurent Aimar	a4fd95b5d5	h264: fix intra 16x16 mode check when using mbaff and constrained_intra_pred. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	979bea1300	check all svq3_get_ue_golomb() returns. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Dustin Brody	a3e215cdc9	svq3: propagate codec memory allocation failure in context init Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	14 years ago
Diego Biurrun	657ccb5ac7	Eliminate FF_COMMON_FRAME macro. 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.	14 years ago
Jason Garrett-Glaser	3b7ebeb4d5	H.264: faster write_back_* Avoid aliasing, unroll loops, and inline more functions.	14 years ago

Jason Garrett-Glaser	504811baea	Roll back 4:4:4 H.264 for now Needs some ARM/PPC asm modifications.	14 years ago

Baptiste Coudurier	93d06bd1df	svq3: Check negative mb_type to fix potential crash. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Baptiste Coudurier	8dfc6d1f7c	svq3: Move svq3-specific fields to their own context. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Ronald S. Bultje	cdca7c378e	svq3: Do initialization after parsing the extradata 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.	14 years ago
Reimar Döffinger	f44967b1b5	Use av_fast_malloc instead of av_fast_realloc. Avoids a memleak, is less code and might be faster.	14 years ago

Anton Khirnov	8ed2ae09a2	lavc: mark hurry_up for removal on next major bump It has been deprecated for about five years, skip_idct/skip_frame should be used instead.	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Diego Elio Pettenò	e7e2df27f8	Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit `d36beb3f69`)	14 years ago

Jason Garrett-Glaser	2a1f431d38	H.264/SVQ3: make chroma DC work the same way as luma DC 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	14 years ago
Jason Garrett-Glaser	290fabc684	Port SVQ3 to use the new mb_luma_dc method of storing luma DC coefficients. 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	14 years ago
Jason Garrett-Glaser	2e18660115	Fix SVQ3 Regression in r26336-7. Originally committed as revision 26341 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	19fb234e4a	H.264: split luma dc idct out and implement MMX/SSE2 versions 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	14 years ago
Alexander Strange	0f01602362	SVQ3: Allow decoding if thread_count is > 1 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	14 years ago
Baptiste Coudurier	891263eff2	Fix svq3 watermark log uncompress on 64bit, probably fixes issue 1263 Originally committed as revision 23620 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. 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	15 years ago
