Michael Niedermayer	d6975eb82b	use qscale_table in adaptive quant some PSNR/bitrate improvement for adaptive quant Originally committed as revision 7346 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	59743d16c7	dont randomly disallow intr4v in adaptive quant some PSNR/bitrate gain if adaptive quant is used initalize qscale_table correctly (it was pretty much random since the qp->lambda change) this probably has not much effect as the table isnt used currently IIRC Originally committed as revision 7342 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	19 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	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
