[Live-devel] How to send extra data linked to frames of a RTSP stream?

[Matthew Czarnek]

I would like to send some small pieces of data that is associated with a
RTSP packet alongside the packet within the stream.

I see that RTSP supports subtitles, is it possible to use subtitles to send
information associated with a frame to the client? I'm seeing a few 15 year
old posts about live555 not supporting subtitles but not seeing any that
are up to date.. which I assume means still not supported.

Is there some other way to do it within the RTSP stream itself? Maybe if I
send a custom packets? Or does it have to be sent separately via something
like sockets, and linked to the stream via timestamps or something like
that?

Thank you,
Matt
