Subject: [Ffmpeg-devel] [PATCH] ASF Duration

Originally committed as revision 6407 to svn://svn.ffmpeg.org/ffmpeg/trunk

-b of ffmpeg is bits/sec not kbits/sec, as already was the case for the
AVOption. "k" and "M" suffixes are available though.

tabs removed and regression.sh fixed (it was missing in the patch) by me

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).

- really produce readable files (instead of 0 byte files or headers only)
 - use bitexact, fastint dct, simple idct and qscale
 - gives consistent results across several archs
 - still fails on altivec ppc

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?
