There's a patch for this that i think Anton wrote and then Timo 
improved. It was posted sometime ago.

How do you propose to do this? And would you be willing to write the 
framework for it?
It certainly sounds useful, as existing bsfs like vp9_superframe_split 
already generate spec non-compliant packets, and they ideally should not 
be publicly available.
