OBS Receiver Setup

Add each stream as a separate OBS Media Source.

For every source:

  1. Add Sources > + > Media Source.
  2. Uncheck Local File.
  3. Set Input to the relevant SRT URL.
  4. Set Input Format to mpegts.
  5. Enable Restart playback when source becomes active.

Default URLs

These match config/localcast.example.json when the receiver is listening locally:

video:   srt://0.0.0.0:5100?mode=listener&latency=120000&timeout=5000000
desktop: srt://0.0.0.0:5101?mode=listener&latency=120000&timeout=5000000
voice:   srt://0.0.0.0:5102?mode=listener&latency=120000&timeout=5000000

If using a passphrase, append:

&passphrase=YOUR_SECRET&pbkeylen=16

OBS should be open before the sender starts if OBS is the SRT listener. If a source gets wedged, deactivate and reactivate the Media Source before changing ports; port churn is a symptom, not a configuration strategy.

Source Layout

Recommended OBS scene:

Husband PC - Video       Media Source, monitor off
Husband PC - Desktop     Media Source, audio only, monitor as needed
Husband PC - Voice       Media Source, audio only, monitor as needed

Mute the video source if it carries no audio. Keep audio filters on the separate audio sources.
