Hi there,

Thanks for all your efforts!

I'm trying to setup a simple rtsp proxy to expose my ip camera via a docker container.

With this command:
docker run --rm -it --network=host -e RTSP_PATHS_TEST_SOURCE=rtsp://admin:[email protected]/h264/ aler9/rtsp-simple-server

Log output:

It seems to connect (I can see RTP traffic flowing on Wireshark), however, it then sends a TEARDOWN (TEARDOWN rtsp://rtsp://192.168.126.208/h264/ RTSP/1.0\r\n) not sure if this is causing a failure but it's prepending rtsp:// twice to the URL. I can see it tries to do an A query for "rtsp" to the DNS server, which does not have an answer for this.

FYI, I can connect to this stream using my VLC client at the same URL.

Cheers
Pieter
