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 |
