How does this impact other hwaccels or software decoding? Because
those cases seem to be working just fine the way it is now, from what
I can tell.

Also, in the VA-API calling code, are you setting avctx->slice_flags
to SLICE_FLAG_ALLOW_FIELD? Because that forces an end_frame call for
every field, which may be all that is needed here.
