Can anyone point to me, how to use the record facility.
What support we need in media server for getting the data streamed to the media server
Are you referring to the Record action in AVTransport? As I understand, this is something for the renderer, and not for the server, meaning - when a renderer is streaming something from the server, and the Record action is invoked the renderer starts saving the stream.
I may be wrong of course, but that's how I understand it.
