Hi Felix,
I have a similar problem.
After 3 days playing I couldn't access the RTP/RTCP server PC anymore. Pinging
didn't work either. Only after a reboot everything is ok.
A few days later the same happened.
And now I discovered something even stranger:
I sniffed the network traffic going to and going from the server to see if I
was missing anything:
Analyzing the traffic I saw a stream coming from the server that was 35Mbps
analyzing it some more it is a RTCP stream -> this doesn't seems OK (a rtcp
stream that is 20 times bigger than the actual video stream)
Seeing this I did some more experiments:
1) first I power off power on the server and put it in a separate lan.
After sniffing the network I found 4 multicast streams coming out of it:
- 232.29.51.215:18888 -> rtp video stream from 2Mbps
- 232.29.51.215:18889 -> rtcp sender reports (a few of them)
- 232.218.63.39:18890 -> rtp video stream from about 200kbps
- 232.218.63.39:18891 -> rtcp sender reports (just a few of them)
2) A placed a 2 decoders in the network and ask the rtsp multicast stream
for both of them
I received the stream and could decode it (the stream was 232.29.51.215:18888)
But the rtcp stream 232.29.51.215:18889 suddenly became enormous about 35 Mbps
I think this is a bug and this is causing eventually the strange behavior I
mention earlier (not reacting on ping anymore)
What is your video source ? Is it h264 or something else ?
Felix.
