Loren Merritt	46803f4f67	optimize imdct_half: remove tmp buffer. skip fft reinterleave pass, leaving data in a format more convenient for simd. merge post-rotate with post-reorder. Originally committed as revision 14700 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Loren Merritt	5d0ddd1a9f	split-radix FFT c is 1.9x faster than previous c (on various x86 cpus), sse is 1.6x faster than previous sse. Originally committed as revision 14698 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Loren Merritt	b9fa32082c	exploit mdct symmetry 2% faster vorbis on conroe, k8. 7% on celeron. Originally committed as revision 14207 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Diego Biurrun	245976da2a	Use full path for #includes from another directory. Originally committed as revision 13098 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Ramiro Polla	40d0e665d0	Do not misuse long as the size of a register in x86. typedef x86_reg as the appropriate size and use it instead. Originally committed as revision 13081 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Ronald S. Bultje	b550bfaa61	Add libavcodec to compiler include flags in order to simplify header include paths in the source files. mostly from a patch by Ronald S. Bultje, rbultje ronald.bitfreak net Originally committed as revision 9034 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
Loren Merritt	a4eb118a41	cosmetics (indentation) Originally committed as revision 6313 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Loren Merritt	f469094c9b	tweak ff_imdct_calc_3dn2 Originally committed as revision 6312 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Loren Merritt	1e4ecf26f5	ff_fft_calc_3dn/3dn2/sse: convert intrinsics to inline asm. 2.5% faster fft, 0.5% faster vorbis. Originally committed as revision 6023 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Loren Merritt	ee5df92750	emms -> femms Originally committed as revision 5965 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Loren Merritt	2494bdd90d	gcc 2.95 and 3.4.x on x86 32bit without fomit-frame-pointer can't even find 5 registers for asm input. 0.5% slower vorbis. Originally committed as revision 5964 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Loren Merritt	1b87c40245	slightly faster ff_imdct_calc_3dn2() on amd64. (gcc added a bunch of useless movsxd) Originally committed as revision 5962 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Loren Merritt	bcfa3e58ee	3dnow2 implementation of imdct. 6% faster vorbis and wma. Originally committed as revision 5954 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Zuxy Meng	82eb4b0f1b	3DNow! & Extended 3DNow! versions of FFT Patch by Zuxy Meng, zuxy <<dot>> meng >>at<< gmail <<dot>> com Minor non-functional diff-related fixes by me. Originally committed as revision 5125 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
