Are these clients actually decoding and displaying the video (rather than just receiving it)? If so, then perhaps your bottleneck is there - in whatever is doing the decoding? E.g., do you have a separate GPU or something doing the decoding? One way to test this is to use "openRTSP" as your client. "openRTSP" just receives data (and outputs it to a file), but does not decode it. Try running "openRTSP" multiple times (you may wish to use the "-F <filename-prefix>" option to give each output file a different filename prefix, to distinguish them). Then try playing the received files using a media player. (If your video is H.264, and you're using VLC as your media player, then you'll need to rename each video file to have a ".h264" filename suffix.) This will tell you whether or not data loss is happening. Ross Finlayson Live Networks, Inc. http://www.live555.com/
