Co-streaming an IRL moment is half the fun. One person is out in the field with the rig, and everyone else wants that feed live in their own stream. Play keys make that clean: one publisher (you), a separate named key for each co-streamer, all pulling the same feed.
How it works
You are the publisher. Your phone or encoder bonds and sends your feed to the relay as usual. A play key is a separate, shareable credential that lets someone else pull that same feed into their own OBS. Each key is its own, so you can name them, hand them out, and turn any of them off later without touching your stream.
This is what makes a collab simple: you do not re-stream anything, and your co-streamers do not need your login. They just get a key.
Create and share a play key
- In your dashboard, open your SRTLA endpoint and go to the Play Keys tab.
- Add a play key and name it for the person it is for, for example "Guest Streamer".
- Copy the Media Source URL the dashboard generates for that key.
- Send that URL to your co-streamer.
Repeat for each person. Each gets their own named key, and you can disable or delete any of them at any time.
What your co-streamer does
They add your Media Source URL as a media source in their own OBS, the same way they would add any IRL feed:
- In OBS, add a Media Source to a scene.
- Paste in the Media Source URL you sent.
- Set Network Buffering to about 1 MB and Reconnect Delay to a few seconds for a steady pull.
Now your live IRL feed shows up inside their stream, pulled straight from the relay.
Name your keys per person
Give each play key the streamer's name. When a collab ends, you disable or delete just that one key, and the rest keep working. No resetting your whole setup.
All of this assumes the publishing side is already working. If it is not, SRTLA bonding explained and connect Moblin cover getting a feed into the relay in the first place.
FAQ
- How many streamers can I share my feed with?
- As many as you need. You create a separate, named play key for each person, and they all pull from your single publisher feed. You can enable, disable, or delete each key on its own.
- Do co-streamers see exactly what I am streaming?
- Yes. Every play key pulls the same feed you are publishing. It is your live IRL feed, shared, not a separate stream.
- Is this only for SRTLA endpoints?
- Yes. Play keys are generated on an SRTLA endpoint. Your own publish key also works for playback if you need it.
