Hi, Apologies for the delay in replying.
I've repeated the test using openRTSP as the client, but with the rest of the chain as before. I'm running 'openRTSP -d 30 rtsp://192.168.202.220:8554/a2' and then checking the size of the video file that is created. The first time it's 22215396 bytes, and this file is playable by VLC. After openRTSP has quit, I run it again, and this time I get a file that's only 210560 bytes (barely 1% of the size of the original file). To re-iterate, the chain is: Multicast M2T stream -> Live 555 RTSP server with a MPEG2TransportUDPServerMediaSubsession -> openRTSP If you need any further information, please let me know. Thanks as ever.

Andy, I was not able to reproduce this (using “testOnDemandRTSPServer” with “testMPEG2TransportStreamer”, which streams over RTP/UDP rather than raw-UDP; this should not make any difference). > In all cases, I was testing using VLC as a client. Instead, I used “openRTSP” as a client, with the “-n” option (which tells “openRTSP” to report when it receives the first data). Are you able to reproduce your problem with “openRTSP” as a client? I suggest both stopping the client using Control-c, and stopping it by explicitly specifying a stream duration - e.g., by adding “-d 10” to the “openRTSP” command line. If not, then this might be a problem with VLC, not with our code.
