Describe the issue

fallback dont works as described - "url to redirect clients to when nobody is publishing to this path".

Describe how to replicate the issue

1. start the server
2. publish with config:

paths:
# For Debugging - my proxied home camera
  test:
    source: record
    sourceProtocol: automatic
    sourceOnDemand: yes
    sourceOnDemandStartTimeout: 10s
    sourceOnDemandCloseAfter: 10s
    #publishIps: [127.0.0.1]
    fallback: rtsp://127.0.0.1:8554/fallback

  fallback:
    source: record
    runOnDemand: ffmpeg -re -stream_loop -1 -i "/opt/icmedia/fallback.mp4" -c copy -an -r 1 -f rtsp "rtsp://127.0.0.1:8554/fallback" -hide_banner
    runOnDemandRestart: yes
    sourceProtocol: automatic
    sourceOnDemand: yes
    sourceOnDemandStartTimeout: 10s
    sourceOnDemandCloseAfter: 10s

Fallback movie src:
https://github.com/brandousov/pix/blob/main/fallback.mp4

When I have not publishing to path, or stops publishing, VLC just stops translation and trying to reconnect, no alternative (fallback) video shown instead.

Did you attach a network dump?

no

Hi, I think you have to change your config similar to :

  test:
    source: record
    sourceProtocol: automatic
    sourceOnDemand: yes
    sourceOnDemandStartTimeout: 10s
    sourceOnDemandCloseAfter: 10s
    #publishIps: [127.0.0.1]
    fallback: rtsp://127.0.0.1:8554/fallback1<-----"change the path"

  fallback1:<----"here too"
    source: record
    runOnDemand: ffmpeg -re -stream_loop -1 -i "/opt/icmedia/fallback.mp4" -c copy -an -r 1 -f rtsp "rtsp://127.0.0.1:8554/fallback" -hide_banner
    runOnDemandRestart: yes
    sourceProtocol: automatic
    sourceOnDemand: yes
    sourceOnDemandStartTimeout: 10s
    sourceOnDemandCloseAfter: 10s```

The fallback path is reserved I think.

The fallback path is reserved I think.

Thank you. It did not works:

Hello,
In the fallback parameter, you have to provide the public ip of the server, not the local one (127.0.0.1).

For instance, if the server public IP is 10.0.0.1, the configuration is

paths:
# For Debugging - my proxied home camera
  test:
    source: record
    sourceProtocol: automatic
    sourceOnDemand: yes
    sourceOnDemandStartTimeout: 10s
    sourceOnDemandCloseAfter: 10s
    #publishIps: [127.0.0.1]
    fallback: rtsp://10.0.0.1:8554/fallback

  fallback:
    source: record
    runOnDemand: ffmpeg -re -stream_loop -1 -i "/opt/icmedia/fallback.mp4" -c copy -an -r 1 -f rtsp "rtsp://127.0.0.1:8554/fallback" -hide_banner
    runOnDemandRestart: yes
    sourceProtocol: automatic
    sourceOnDemand: yes
    sourceOnDemandStartTimeout: 10s
    sourceOnDemandCloseAfter: 10s

Anyway, since this is not obvious, i'd better add support for relative paths (i.e. /fallback).
