[Itach1Uchixa]

Which version are you using?

v0.12.2

Which operating system are you using?

Linux

Describe the problem

If I use config below
config.yml

paths:
  all:
  office:
    source: rtsp://external-ip-camera:554/
    sourceProtocol: tcp
    runOnPublish: ffmpeg -re -i rtsp://localhost:$RTSP_PORT/$RTSP_PATH -c:v libx264 -preset ultrafast -f rtsp rtsp://localhost:$RTSP_PORT/compressed
    runOnPublishRestart: yes

I can watch rtsp://localhost:8554/office with vlc player. I wanted to change parameters of stream. I tried everything but server output is:

I also tried to create another stream with runOnInit and faced same problems.
Tried docker and standalone versions.

Did you attach a network dump?

no

Hello, the runOnPublish command is run only when someone is publishing to the path - in this case you're not publishing, you're using the path as a proxy, so a working configuration could be

paths:
  all:
  office:
    source: rtsp://external-ip-camera:554/
    sourceProtocol: tcp
    runOnInit: ffmpeg -re -i rtsp://localhost:$RTSP_PORT/$RTSP_PATH -c:v libx264 -preset ultrafast -f rtsp rtsp://localhost:$RTSP_PORT/compressed
    runOnInitRestart: yes

ensure that ffmpeg is installed on the system - it is NOT bundled with the Docker image - and rtsp-simple-server is installed on the system. If necessary, try debugging a little, for instance by introducing a starting delay

paths:
  all:
  office:
    source: rtsp://external-ip-camera:554/
    sourceProtocol: tcp
    runOnInit: sh -c 'sleep 5; ffmpeg -re -i rtsp://localhost:$RTSP_PORT/$RTSP_PATH -c:v libx264 -preset ultrafast -f rtsp rtsp://localhost:$RTSP_PORT/compressed'
    runOnInitRestart: yes
