I'm trying to create a live555-based RTSP server streaming H.264 via unicast from a live source. I'm able to stream video to the first client without errors, but when the second client connects concurrently to the same URL it fails to find PPS/SPS NALs in the beginning of H.264 stream (ffmpeg client log goes below):

But unfortunately it simply is not called when the second client connects (I double-checked that in debugger). Can you provide more detail on how to make the second concurrent client start its RTP session from correct PPS/SPS NALs? - Dmitry Bely _______________________________________________ live-devel mailing list live-devel@lists.live555.com http://lists.live555.com/mailman/listinfo/live-devel
