[Live-devel] Unable to proxy an rtsp stream on alternate port

[Craig Matsuura]

If it helps here is the commandline I ran and proxy in question:

./live555ProxyServer -V rtsp://172.16.10.106:554/live.sdp rtsp://172.16.10.113:554/live.sdp rtsp://172.16.10.110:554/live.sdp rtsp://172.16.10.112:554/live.sdp rtsp://172.16.10.105:554/live.sdp rtsp://172.16.10.102:554/Video-0 rtsp://172.16.10.109:554/live.sdp


RTSP stream, proxying the stream "rtsp://172.16.10.112:554/live.sdp"<rtsp://172.16.10.112:554/live.sdp> on rtsp://172.16.10.101:8554/proxyStream-4

I apologize for the last post being so big and the duplicate posting, I moved the log output to pastebin.

Ok, I have managed to create the problem where a working camera providing an RTSP stream to the rtsp proxy does not work via the proxy.  I downloaded the latest code and compiled it on my laptop and setup the proxy to use the cameras providing my RTSP streams.

I tested the proxy stream using gstreamers playbin2 (this has always worked for me) and vlc.  Both failed to display my camera.  I have other streams setup on the proxy server with the same model of cameras that work great with both playbin2 and vlc.

I tried the openRTSP test, but wasn't sure what the expected output should be. (I paste it below).

Here is the log out using -V

I'm wondering if there is a specific message I can look for in the logs
when at level 2 that will indicate if a proxies stream has failed?  I'm
using the proxyServer example and at times the stream stops streaming.
I can see the OPTION commands going out to the camera with a response,
but connecting a client to the proxied stream does not work.  Not sure
if it is due to loosing a connection, but what I find strange is the
OPTION command appears to respond.  Is there something in the response
of the OPTION that indicates a problem?

I'm not sure.  Why don't you post the diagnostic output (from the proxy server) around the time that "connecting a client to the proxied stream does not work"?  (And also, please clarify what "does not work" means).
