runOnInit command exited with code 0

[promd]

Hi,
1st off: Thanks for the project! I ended up here after trying ffmpeg commands for days.

scenario:
I need to re-size the rstp stream from a webcam, because the recipient is very picky on resolution. (And the cam is very inflexible).
I did see a variation to the below here in the discussions, but somehow, it does not work. I always get this message:

[path unifi42n] runOnInit command exited with code 0

[EDIT]
The FFMPEG command works in a shell if I run it directly on the stream from the Cam and publish that to the server. - So the syntax and parameters are ok.

Any ideas what I am doing wrong ?

paths:
  unifi:
    source: rtsp://192.168.000.000:7447/HZ36G8j2FE6OaM3p
  unifi42n:
    # This command works in a shell:
    #         ./ffmpeg -i rtsp://192.168.000.000:7447/HZ36G8j2FE6OaM3p -acodec copy 
    #        -c:v libx264 -vf scale=640x480 -preset ultrafast -b:v 600k -max_muxing_queue_size 1024 
    #        -f rtsp rtsp://localhost:8554/test
    # Newlines added for readability!
    runOnInit: ffmpeg -i rtsp://localhost:$RTSP_PORT/unifi -acodec copy 
                   -c:v libx264 -vf scale=640x480 -preset ultrafast -b:v 500k -max_muxing_queue_size 1024 
                   -f rtsp rtsp://localhost:$RTSP_PORT/unifi42n
    # Restart the command if it exits suddenly.
    runOnInitRestart: yes

Thanks for the hint, @Curid !
However, it fails in the same way if I hard-code the ports in the Config.
But, I am now also getting

closed (no one is publishing to path 'unifi42n')

All streams and commands work stand-alone.

• rtsp://localhost:8554/unifi -> works
• rtsp://192.168.000.000:7447/HZ36G8j2FE6OaM3p -> works
• rtsp://localhost:8554/unifi42n [if I run the ffmpeg externally!] -> works

Any further hints are appreciated!

Does FFmpeg throw any errors? Add -loglevel debug to the runOnInit command.

ok, problem solved.
ffmpeg could simply not be found.

Maybe if anybody is still in the same situation:

This tool does (obviously) not come with ffmpeg bundled!
If you want to make modifications to the streams using ffmpeg, make sure it is in the same folder, or it is added to PATH !

Thanks to @Curid for his/her efforts !
