[Live-devel] RTPSource for mime "application/VND.ONVIF.METADATA"

FYI, if you're OK just receiving otherwise unknown RTP payload formats using a "SimpleRTPSource", then you don't need to do any subclassing to do this.  Instead, just call "MediaSession::initiate()" with a "useSpecialRTPoffset" parameter of 0.  This will tell the LIVE555 code to implement this (otherwise unknown) RTP payload format using a "SimpleRTPSource" - without the need to do any subclassing or adding any code of your own.

This RTP payload format is not defined in any IETF RFC, but - according to 'ONVIF' documents - it contains just XML text, without any special RTP headers, and therefore you should not need any special "RTPSource" subclass in order to receive it.  "SimpleRTPSource" should be sufficient, and - as I noted above - you can get this automatically just by passing a "useSpecialRTPoffset" parameter of 0 to "MediaSession::initiate()".
