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).

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?

132041f06f While adding stereo rematrixing, I came across something that needs to 
be fixed even without adding the feature.  The output correctly uses 4
dummy values for the rematrixing flags in block-0, but the bit
allocation routine does not take these bits into account.  From what I
can tell, there was a patch in 2003 that corrected the output to make it
DVD and spec compatible, but it didn't correct the bit allocation.  It's
only 4 bits over the entire 6 blocks, so overflow errors would happen
rarely or never, but it's still worth fixing.  So here is a fix.

b44985ba12 store the number of runs to avoid storing the last run value 
about 10% lower bitrate for -qscale 32 (forman & some music video)
worst case bitrate increase <0.1% (lossless or low qscale)
and now the bad news, even though this just adds a single subtraction and an if() into the medium sized unpack_coeffs() loop and the if() will only be false once per unpac_coeff() call, gcc produces 50% slower code, i didnt look at the generated asm yet, not sure if i want to ...

a0a74ad9f0 increasing precission of the quantization parameter 
this is needed as the quantization stepsize for each subband is also in this precission and insignificant changes to the wavelet like scaling its coefficients slightly differently would lead to wildly variing PSNR and bitrate
note, a encoder could also simply choose to leave the least significant bits of the quantization parameters zero which would give the exact previous behaviour except a y very tiny number of bits in  the header
