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. > , then I would like to know if it's possible to support this mime in some > next live555 release ? 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()".
