[Ffmpeg-devel] cbp

[Marcel Wolf]

Guys
WHat is the difference between cbpc cbpy and cbp? I thought the cbp was
a bit definition of what blocks are non-zero (1=non-zero)? For example,
the 6-bit value would indicate which block 0-5 is non-zero or 0x3f would
be all non-zero. Is all this true and how are cbpc and cbpy different?
Also, what is gb below?

cbpc = get_vlc2(&s->gb, inter_MCBPC_vlc.table, INTER_MCBPC_VLC_BITS, 2);
            //fprintf(stderr, "\tCBPC: %d", cbpc);

Thanks
Marcel
