Måns Rullgård	68cf92ee5e	Always call avcodec_thread_init() The various avcodec_thread_init() functions are updated to return immediately after setting avctx->thread_count. This allows -threads 0 to pass through to codecs. It also simplifies the usage for apps using libavcodec. Originally committed as revision 21358 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	b4c2ada528	Attempt to fix asm compilation failure. Only tested on gcc 4 & x86_64. Originally committed as revision 21355 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Laurent Aimar	92c6a099ba	H264 DXVA2 implementation It allows VLD H264 decoding using DXVA2 (GPU assisted decoding API under VISTA and Windows 7). It is implemented by using AVHWAccel API. It has been tested successfully for some time in VLC using an nvidia card on Windows 7. To compile it, you need to have the system header dxva2api.h (either from microsoft or using http://downloads.videolan.org/pub/videolan/testing/contrib/dxva2api.h) The generated libavcodec.dll does not depend directly on any new lib as the necessary objects are given by the application using FFmpeg.

Måns Rullgård	5e7dfb7de1	Move COPY3_IF_LT to lavc/mathops.h This obscure macro is only used in motion_est.c so having it in lavc makes more sense. See discussion here: http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2008-November/056561.html Originally committed as revision 21346 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alexander Strange	bec358d683	H.264: Declare bS with DECLARE_ALIGNED_8 for uint64_t casts. Originally committed as revision 21345 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	97775235ec	Simplify/Optimize another of the mbaff loop filter cases. Its faster but too rarely used to make a differnce. Originally committed as revision 21344 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	085d9d98e8	Only calculate the second chroma qp if it differs from the firstin the main loop filter. (a little faster for the common case where they are equal) Originally committed as revision 21342 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	3f50965b28	Mark the h264 c loop filter as av_always_inline av_flatten to make sure its all inlined, its small and horizontal & vertical versions are build out of them. no change as gcc already did this. Originally committed as revision 21333 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	c9640c17ac	skip outer pixels if possible in h264_loop_filter_luma_c(). overall 3.7% faster loop filtering (C version only) Originally committed as revision 21332 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	ebddd2e253	Remove -2 -> -1 remapping, its not needed anymore as we must remap all references per LUT anyway. Originally committed as revision 21323 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	76d81909ae	Update libx264.c to use new libx264 features With b_keyframe instead of IDR for detecting keyframes, ffmpeg should now support periodic encoding with periodic intra refresh (although there is no interface option for it yet). Set the new timebase values for full VFR input support. Bump configure to check for API version 83. Originally committed as revision 21317 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	350fc614b4	Remove code that handles the case of a MB pair to our right being available.

Michael Niedermayer	b6ef858ec7	Move CAVLC 8x8 DCT special case from ff_h264_filter_mb() to fill_caches that way it is also available for ff_h264_filter_mb_fast(). Originally committed as revision 21283 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	6d7e6b2657	Perform reference remapping at fill_cache() time instead of in the loop filter. This removes one obstacle of getting ff_h264_filter_mb_fast() bitexact. code is maybe 0.1% faster Originally committed as revision 21280 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	c988f97566	Rearchitecturing the stiched up goose part 1 Run loop filter per row instead of per MB, this also should make it much easier to switch to per frame filtering and also doing so in a seperate thread in the future if some volunteer wants to try. Overall decoding speedup of 1.7% (single thread on pentium dual / cathedral sample) This change also allows some optimizations to be tried that would not have been possible before. Originally committed as revision 21270 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
