Baptiste Coudurier	72450e50a5	support for Delphine Software .cin files demuxing / audio and video decoding, by Gregory Montoir %cyx A users P sourceforge P net% Originally committed as revision 6659 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	2b5269b51c	moving lps state transition code a little up in the branched asm code (1% faster on P3) Originally committed as revision 6658 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	b99f3cabed	write cabac low and range variables as early as possible to prevent stalls from reading them before they where written, the P4 is said to disslike that alot, on P3 its 2% faster (START/STOP_TIMER over decode_residual) Originally committed as revision 6657 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	d17faef011	use ecx instead of cl (no speed change on P3 but might avoid partial register stalls on some cpus) Originally committed as revision 6656 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	d61c4e731e	make state transition tables global as they are constant and the code is slightly faster that way Originally committed as revision 6655 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	5f3eca121e	10l Originally committed as revision 6654 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	0fa352c7e6	make lps_range a global table its constant anyway (saves 1 addition for accessing it) Originally committed as revision 6653 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	3650b43959	enable CMOV_IS_FAST as its faster or equal speed on every cpu (duron, athlon, PM, P3) from which ive seen benchmarks, it might be slower on P4 but noone has posted benchmarks ... Originally committed as revision 6652 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago

Guillaume Poirier	ab5a1435ec	Move TRANSPOSE8 macro to dsputil_altivec.h. (was duplicated in libavcodec/ppc/vc1dsp_altivec.c nd libavcodec/ppc/mpegvideo_altivec.c, and will be used in upcoming routines for h264_altivec.c) Originally committed as revision 6621 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	9ed92c65f1	moving another bit&1 out, this is as fast as with it in there, but it makes more sense with it outside of the loop Originally committed as revision 6618 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	f1b37db48d	move the &1 out of the asm so gcc can optimize it away in inlined cases (yes this is slightly faster) Originally committed as revision 6616 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	ab0151d163	replace a few and/sub/... by cmov this is faster on P3, should be faster on AMD, and should be slower on P4 its disabled by default (benchmarks welcome so we know when to enable it) Originally committed as revision 6615 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	a6672acf45	reading 8bit mem into a 8bit register needs 2 uops on P4, 8bit->32bit with zero extension needs just 1 Originally committed as revision 6612 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
