I wasn’t able to reproduce this using “live555MediaServer” and VLC as the client. I suspect that the problem is “ffplay”; it’s not a very good RTSP client implementation. I suspect that it’s not really sending a RTSP “PAUSE” command, but is sending a new RTSP “PLAY” command each time it resumes, which will produce the duplicated stream.
