Hi there, I am developing a videoconferencing solution with gstreamer (and SIP) in java. Everything works fine until somebody leaves the conference. The whole pipeline stalls. As I read, this is expected behaviour. I currently try to catch the EOS events of the videomixers sink pads, set the pipe to paused, unlink the respective sink pad and link it to a videotestsrc and then set the pipe to plying again. Unfortunately, that doesn't work. Can somebody tell me how to handle this properly? Thanks guys!!
