Is this ‘ONVIF’-type metadata?  If so, then you would use a “SimpleRTPSink”, as described here:
	http://lists.live555.com/pipermail/live-devel/2021-August/021953.html

If your metadata is being streamed along with a H.264 (or H.265) video stream, then your “ServerMediaSession” would contain two “ServerMediaSubsession” objects - one for the video track, one for the metadata track.  It’s important that the “fPresentationTime” values set by each of your “FramedSource” subclass objects (for the video track, and for the metadata track) be accurate, and aligned with ‘wall clock’ time (the times that you’d get by calling “gettimeoffday()”).
