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

6ba71fc467 This is the second patch for MBAFF support, this adds the deblocking

4e4d983e8b Set keyframe flag only on IDR-frames (needed for reordering across I-frames). 
Read vui bitstream restrictions (allows B-frame delay in advance, rather than waiting till we're out of order.)
