There's a lot of duplicate parsing code here. We should instead reuse 
the existing CBS implementation.

Add https://gist.github.com/jamrial/631a2b0b7dafb3f0a9596a24621cb79d to 
make cbs_apv available in lavf and use the CBS API to parse the 
bitstream (It will have a ff_lavf_cbs_* prefix). See movenccenc.c
