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)

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).

2e52b44e50 AC coefficient weighing (per SMPTE 314M) for the DV encoder and decoder. The

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?

updated the checksums ...
regression test checksum change due to: movenc.c 1.46->1.47
