Michael Niedermayer	642ccefbc8	move mmx quantizer matrixes out of MpegEncContext (23k -> 7k) (no meassureable slowdown) Originally committed as revision 2412 to svn://svn.ffmpeg.org/ffmpeg/trunk	21 years ago
Michael Niedermayer	f818862633	fixing thread safety, this may cause alignment problms (if it does than the stuff should be moved to MpegEncContext) Originally committed as revision 2124 to svn://svn.ffmpeg.org/ffmpeg/trunk	22 years ago

Michael Niedermayer	2ad1516a6c	idct permutation cleanup, idct can be selected per context now fixing some threadunsafe code Originally committed as revision 980 to svn://svn.ffmpeg.org/ffmpeg/trunk	22 years ago
Arpi	3f09f52adf	fdct_mmx -> ff_fdct_mmx (renamed to avoid namespace conflict with xvid) [found by Kim Minh Kaplan] Originally committed as revision 960 to svn://svn.ffmpeg.org/ffmpeg/trunk	22 years ago
Michael Niedermayer	1a684b3d53	fixing encoding at high QPs (was broken after the dct accuracy increase due to too small inverse table) Originally committed as revision 901 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	ad324c9351	dct cleanup more accurate mmx dct (dont discard bits for fun) fixing mmx quantizer bug for qscale%2==1 (bias was slightly wrong) Originally committed as revision 895 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	28db7fce02	slow but accurate integer dct from IJG (should be ok with the LGPL as the old DCT is the fast integer DCT from IJG) per context DCT selection Originally committed as revision 878 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	87f8cab45b	mpeg4 mpeg quantizer encoding Originally committed as revision 844 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago

Juanjo	ef5b1b5a7e	- Advanced Intra Coding (AIC) support for H.263+ encoder, just DC by now. - Bug fix H.263+ AIC tables. - Warning fixes. Originally committed as revision 431 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	d7e9533aa0	fixed msmpeg4 infinite loop if buggy stream rewrote quantizer fixed bias (+10% compression/quality for h263 like codecs) qscale=1 support mpeg1 intra frames looks far less blocky added codec_id field Originally committed as revision 423 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Arpi	3cb32e3d1f	PATCH by Rik Snel <rsnel@cube.dyndns.org> this includes the range for quantized dct coefficients in dct_quantize() (-1023...1023) Originally committed as revision 291 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Arpi	5dfd24ac98	workaround gcc bug "m" (0) avoiding useage of ebx Originally committed as revision 283 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	2f349de286	(commit by michael) mmx & mmx2 quantizer c dct permutation bugfix dont copy input on intra only encodings if it can be avoided dont draw edges on intra only stuff Originally committed as revision 281 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
