Michael Niedermayer	1c2a417f6a	move outcommented START/STOP_TIMER to a hopefully better place for benchmarking ... Originally committed as revision 6605 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	30dc5f56ad	drop failed attempt to optimize *state= c->mps_state[s]; Originally committed as revision 6604 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	c56d23dacf	10l bugfix for some disabled code Originally committed as revision 6603 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	f7d0b68361	first try of a handwritten get_cabac() for x86, this is 10-20% faster on P3 depening on if you try to subtract the START/STOP_TIMER overhead Originally committed as revision 6602 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	5bbe2a5292	remove bytestream_end checks, seems to work fine without them and the bitstream reader doesnt check for the end either Originally committed as revision 6599 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	c010d69a75	decrease ff_h264_norm_shift[] size Originally committed as revision 6596 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	6ff042699f	cleanup Originally committed as revision 6594 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	260ceb6322	branchless renormalization (1% faster get_cabac) old branchless renormalization wasnt faster because gcc was scared of the shift variable (missusing bit variable now) Originally committed as revision 6587 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	99ce10873d	5% faster get_cabac() Originally committed as revision 6586 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	400d0f8e47	disable benchmarking code disable asm optims as the fastest depends on cpu type Originally committed as revision 6582 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	4310580db5	renorm_cabac_decoder_once START/STOP_TIMER scores for athlon Originally committed as revision 6581 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	5659b509c7	refill cabac variables in 16bit steps, 3% faster get_cabac() Originally committed as revision 6578 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Diego Biurrun	b78e7197a8	Change license headers to say 'FFmpeg' instead of 'this program/this library' and fix GPL/LGPL version mismatches. Originally committed as revision 6577 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	2ae7569dc8	() 10l Originally committed as revision 6576 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	ec8f483ab5	several x86 renorm_cabac_decoder_once optimizations START/STOP_TIMER benchmarking code for them please benchmark on P4 & athlon (ill remove the benchmarking code and the always slower variants as soon as p4/athlon benchmarks have been posted or commited) Originally committed as revision 6573 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Loren Merritt	938dd84693	don't try to inline cabac functions. gcc ignored the hint anyway, and forcing it would make h264 slower. Originally committed as revision 6549 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Loren Merritt	bfe328caf0	tweak cabac. 0.5% faster h264. Originally committed as revision 6106 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Loren Merritt	2848ce84d2	don't force asserts in release builds. 2% faster h264. Originally committed as revision 5332 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Diego Biurrun	5509bffa88	Update licensing information: The FSF changed postal address. Originally committed as revision 4842 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

Michael Niedermayer	5e20f836b3	FFV1 codec (our very simple lossless intra only codec, compresses much better then huffyuv) Originally committed as revision 1939 to svn://svn.ffmpeg.org/ffmpeg/trunk	22 years ago
