Stefano Sabatini	987903826b	Globally rename the header inclusion guard names. Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Robert Swain	69fc4da360	Add declarations for the sine tables used in wma.c (half window sizes: 128, 256, 512, 1024 and 2048) to mdct.c. Make them accessible via dsputil.h. Make wma.c use these shared tables. Originally committed as revision 14758 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 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

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

Loren Merritt	6810b93a81	sse2 version of compute_autocorr(). 4x faster than c (somehow, even though doubles only allow 2x simd). overal flac encoding: 15-50% faster on core2, 4-11% on k8, 3-13% on p4. Originally committed as revision 10621 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
