Loren Merritt	0a570e826d	remove mdct tmp buffer Originally committed as revision 14702 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
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	17 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	17 years ago
Loren Merritt	8a37920c9e	r14205 broke vorbis float_to_int on ppc Originally committed as revision 14466 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	4f20b45fbe	Fix h264_loop_filter_strength_mmx2() so it works with PAFF. fixed at least: CVFI1_Sony_D.jsv CVFI1_SVA_C.264 MR6_BT_B.h264 Originally committed as revision 14310 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Loren Merritt	5eb0f2a425	float_to_int16_interleave: change src to an array of pointers instead of assuming it's contiguous. this has no immediate effect, but will allow it to be used in more codecs. Originally committed as revision 14252 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 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

Kostya Shishkov	bb68f8a2b6	Monkey's Audio decoder vector functions work on input with length a multiple of 16. Reflect that fact in the documentation for them. Originally committed as revision 14148 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Alexander Strange	f67a10cd0c	Define mm_flags/support to be 0 on architectures where they don't exist. Make sure we don't try to set them if that's the case. This lets dct-test and fft-test build with --disable-mmx on x86, but not yet on ARM. Originally committed as revision 13957 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
