I don't know much about RTP, so I may not have caught up any RTP semantics
issue.
You're using a gmail.com email for author info - maybe this needs to be the
Collabora one,
as well as a copyright + year line.

I don't think you need that. There will be no Vorbis comment metadata through
RTP, will there ?

Rates are constrained to 8000, 12000, 16000, 24000, 48000 only, but this is not
inherent to the Opus stream. So caps should be just audio/x-opus here.

Usually better to use the _OBJECT variant, it helps to dintinguish which object
the log comes from in debug logs.

Should this not be size instead of payload_len ?
If payload_len is larger than size, crash. If it's less, some of the Opus data
will be discarded.
