Michael Niedermayer	ed1dfc4970	remove pretty much useless skiping of some predictors this has pretty much no quality or speed effect except very small random changes Originally committed as revision 7202 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago

Michael Niedermayer	0bd2483a75	replace MULL by MULH + shift in dct32() (code is very slightly faster, and the compiler should be able to optimize the shift away on 64bit archs) Originally committed as revision 6045 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago

Justin Ruggles	a403fc0324	flac-lpc patch by (Justin Ruggles jruggle earthlink net) tabs removed and regression.sh fixed (it was missing in the patch) by me Originally committed as revision 5572 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Justin Ruggles	e71bcc3798	flacenc - rice param search patch by (Justin Ruggles jruggle earthlink net 1) search for optimal rice parameters and partition order. i also modified the stereo method estimation to use this to calculate estimated bit count instead of using just the pure sums. 2) search for the best fixed prediction order 3) constant subframe mode (good for encoding silence) Note that the regression test for the decoded wav file also changed. This is due to FFmpeg's FLAC decoder truncating the file, which it did before anyway...just at a different cutoff point. The generated FLAC files are still 100% lossless. With this update, FFmpeg's FLAC encoder has speed and compression somewhere between "flac -1" and "flac -2". On my machine, it's about 15% faster than "flac -2", and about 10% slower than "flac -1". The encoding parameters are identical to "flac -2" (fixed predictors, 1152 blocksize, partition order 0 to 3). Originally committed as revision 5536 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

Dan Maas	2e52b44e50	AC coefficient weighing (per SMPTE 314M) for the DV encoder and decoder. The performance impact is less than 1%. Patch by Dan Maas (dmaas at maasdigital dot com) Originally committed as revision 5070 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Dan Maas	6df5f6ae51	size[0-3] are not initialized (and can get random negative trash values), so the comparison with vs_total_ac_bits is messed up on the first couple loop iterations, leading to AC underflows. the b->prev[] pointers were not being maintained correctly. We potentially have to update b->prev[] both before and after the area whose VLC length is getting adjusted. this also might fix the ppc regression failure? patch by (Dan Maas <dmaas maasdigital com>) Originally committed as revision 5064 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

Michael Niedermayer	47ad9abaa5	fixing second last time François Revol applies a patch without running the regression tests, next time his account is disabled Note, if you think thats too harsh, look at the cvs history he has broken the regression tests many times and has not once updated the checksums ... regression test checksum change due to: movenc.c 1.46->1.47 "finally found what those >138 codes were... crappy compressed 5bit ascii. this gets them correctly, and adds setting track" Originally committed as revision 4826 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
