[Live-devel] testRTSPClient and MJPEG decoding

Yes, but you don't have to concern yourself with how our code works.  As I said before, the data that the application-level client code (in this case "testRTSPClient") receives should be a complete JPEG video frame each time.

What happens when you try playing the stream using VLC?  (VLC also uses our RTSP/RTP client code.)

You should also check the value of "numTruncatedBytes" (to make sure that it's zero).  If it's non-zero, then that means that your buffer size was too small.
