Describe the issue

I have setup rtsp proxy with one source - h264 video + g711U audio
I can take source directly with rtsp://ip/av0_0
This link setup as source for mediamtx path

If i play stream directly with SMPlayer - all fine, stream plays for a moment, when i stopped it.
But if i play by proxy - got this:

• stream plays, all fine
• after ~2minutes stream suddenly stopped with messages in log:
  2023/04/26 16:59:30 INF [path 10.154.249.2] [rtsp source] stopped
  2023/04/26 16:59:30 INF [RTSP] [conn 127.0.0.1:52970] closed (terminated)
  2023/04/26 16:59:30 INF [RTSP] [session 381853316] destroyed (terminated)

Describe how to replicate the issue

1. start the server
2. publish with rtsp
3. read with rtsp

Did you attach the server logs?

yes

Did you attach a network dump?

yes (direct.pcap && proxy.pcap)

Even without clients (setup always remux)

Hello @Forest-fox, i'm trying to debug the logs you provided but i think you're reporting two separate issues:

• the initial log you posted reports [path 10.154.249.2] [rtsp source] stopped - probably it has to do with sourceOnDemand: yes
• the second log you posted reports [rtsp source] ERR: EOF - probably it's issue v0.23.0 drops with Reolink RLC-520A #1812

[Forest-fox]

Yes, issue is second variant with [rtsp source] ERR: EOF / muxer destroyed (terminated)

[Forest-fox]

Have checked version 0.23.2 - also affected
Log, configuration and network dump - 0.23.2-logs.tar.gz

[aler9]

From the logs it seems that the camera closes the TCP connection after exactly 2 minutes and 15 seconds. This may be linked to the ability to keep a RTSP session running even when its TCP connection gets closed, which is currently missing (bluenviron/gortsplib#162).

If this hypothesis is right, you might be able to temporarily fix the issue by setting sourceProtocol: tcp int he configuration file.

[Forest-fox]

Tried to set sourceProtocol: tcp for path - not working. Same behavior.

[aler9]

Can you post a network dump of 3 minutes of communication between SMPlayer and the camera? this is needed in order to compare a working setup with the server behavior.

Hello, from the logs you posted it seems that the difference between MediaMTX and SMPlayer is that MediamTX doesn't send RTCP receiver reports to the camera, because the camera doesn't send RTCP sender reports, while SMPlayer, which is GStreamer-based, sends them anyway without waiting for sender reports.

I've created a fix (bluenviron/gortsplib#318) but before merging it i need you to test the following nightly release in order to check whether the issue has been solved.

[Forest-fox]

Thanks! I'll test at Monday and give feedback.

[Forest-fox]

I can confirm, that problem resolved with fixed version.
None errors. Stream works fine for more than 10 minutes.

added in v0.23.7
