>AVTransport, the new container I'm working on, supports more flexible signalling of decoded but discarded refs. Still WIP so no support for it in FFmpeg, but hopefully not for too long.

Promoting your own work is fine but AFAIU, OP specifically wants cutting in to MP4. I don't reckon AVTransport is really an option for them.

(And then using the same name as the old IETF working group for RTP is confusing to me.)
