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

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.	13 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

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
Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
