The problem may be with your media player application - which would have nothing to do with us.<div><br></div><div>Try running "openRTSP" <<a href="http://www.live555.com/openRTSP/">http://www.live555.com/openRTSP/</a>> as your RTSP client. Rename the output file to have a ".h264" filename, and try playing this file using VLC (as your media player). If this works, then you should also be able to use VLC as a RTSP client, to play the stream directly.</div><div><br></div><div>If this doesn't work, then send us the diagnostic output from "openRTSP"; that might tell us what's going wrong.</div><br><br><div apple-content-edited="true">
