Looks good, I'm going to push it, but one small thing:

That looks a bit odd, since we would call end_frame only when the
picture structure change, and that never happens for progressive
contents. I think it should look something like:

> target_surface_priv->picture_structure != picture_structure ||

So we call end_frame under the following conditions:
1. begin_frame was called (picture structure is set) AND (
2. picture structure changes OR
3. ref frames change OR
4. mb address is (0,0)
)
