Justin Ruggles	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. patch by (Justin Ruggles {jruggle earthlink net) Originally committed as revision 4179 to svn://svn.ffmpeg.org/ffmpeg/trunk	20 years ago

Michael Niedermayer	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 ...

Michael Niedermayer	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 Originally committed as revision 4115 to svn://svn.ffmpeg.org/ffmpeg/trunk	20 years ago
