Hello everyone, Following the H.264 API cleanup, and with all the lessons learned from it, here's a revisit on the MPEG-2 API. The biggest changes are: * Drop slice size and offset parameters, given the API doesn't seem to be designed to work per-slice. * Convert all the 1-bit syntax elements from structure fields to bits in a bit field flags field, following the other codec APIs. * Split the sequence, picture and slice headers to separate controls. This is build tested only, I haven't yet modified the existing Ffmpeg-based implementation, as I'd like to have some consensus first. Reviews and feedback are appreciated! v2: * Fixed bad use of boolean negation in a flag, which was fortunately reported by 0day bot.
