The code passed H264Picture* and Picture*, and assumed the
hwaccel_picture_private field was in the same place in both

FFmpeg (and probably subtly breaks in Libav too).

Yes, it looks like it. I admit, Thumb was something of an afterthought;

An updated patch series. The main difference here is that for Thumb targets,
it's assumed that interworking is not supported, so individual functions are
either assembled as Thumb, or omitted if they cannot be supported without a
major refactoring.

This is a second or alternative way that would allow us to deprecate J formats
without breaking AVCodec API. Instead of creating a monster struct with any
possible
color combination, I propose to supply a list of formats which have to be

as full range, by adding a .pix_fmts_full to
This struct unambiguously describes how the bits of a pixel should be
