Michael Niedermayer	396a5e6837	store a few values in the header as difference to the last this makes frames a few bytes smaller (0.1% for high bitrate but >1% for low bitrates) Originally committed as revision 7401 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Allan Hsu	148c9bdbb8	Patch for the FLV muxer to supply more complete metadata in the onMetaData header. Patch by Allan Hsu <allan at counterpop dot net>. Originally committed as revision 7382 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	d951bb9a5c	test DIRECT{0,0} too if flag mv0 is used slight PSNR/bitrate increase Originally committed as revision 7361 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Baptiste Coudurier	49f1ac5a3d	change mpeg2 intra vlc test to advanced one, add qprd trell and b frames Originally committed as revision 7349 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
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	2f16af0667	skip motion estimation and encoding of non direct-0,0 MBs if the next MB is skiped (mpeg4 doesnt allow such MBs and in the past we did ME and encoding until at the end we droped them, so this should be faster though i didnt benchmark it, benchmark welcome) Originally committed as revision 7343 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

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	19 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
