Oh, indeed, that was me. That proposed patch is broken though. I
crafted a proper one - which should be correct - and forwarded it to
the development list upstream:

http://ffmpeg.org/pipermail/ffmpeg-devel/2018-July/231816.html
https://patchwork.ffmpeg.org/patch/9566/

But this patch was never merged, or even reviewed.

I can't pitch in on this one. I don't know whether the mpegts sub-muxer
of rtp_mpegts parses mpegts's options, and whether these can be passed
on to rtp. I experimented a bit, but have a hard time interpreting the
results. Someone else should comment.
