I'm wondering if there isn't a bsf that could do this in a cleaner way than messing with codec internals in a muxer.
I thought about that too, but in the end I sticked to the more simple approach, because I could not decide which would be better, adding a single new bsf which works for any codec you may want to mux into mpegts (h264, hevc, av1) or hack some new options to existing *_metadata bsf-s to make them create mpegts-compliant output.
The problem with using *_metadata is that I am not sure if more complex insertion rules belong to those filters, and the way they work - parsing everything with the CBS framework - they have significant CPU overhead.
A separate BSF could use the same or very similar code as mpegtsenc.c right now, but by having it separate we have to maintain it separately from mpegtsenc, and that can also cause problems, if a newer version of mpegtsenc expects the BSF to do something different than the older version...
