Unless you have a 10+ years old camera, the baseline profile is a lie.
Baseline FMO and ASO are too complex for the benefit. So for these I'd just
make an adapter that edits the sps. Remember that nothing in GStreamer or
Ffmpeg can decode baseline.

For high profile, transcoding seems to be the only guaranteed way. You
should try and negotiate through SDP, but you need transcoding. When done
on-demand, you can tailor the load to the number of viewers (and combine
viewers watching the same feed). This is how you keep your cloud cost
aligned with usage.
