Are you sure these "hints" come from the source? Reading the patch, it seems
to make the encoder respect the forced_key_frames option, it has no link
with the source materiel.

Following the picture type from the source would be catastrophic: imagine
transcoding DVD or DVB content with at least one keyframe per second.
