So you want to stream on CB, SC and maybe another site at the same time, but you don’t know how to do it from OBS?
You can do it with a free OBS plugin called obs-multi-rtmp:
https://github.com/sorayuki/obs-multi-rtmp/releases
Click Assets and you will see drop down menu, take exe for windows or pkg for mac
It basically lets OBS send the same stream to more than one site at once. The OBS plugin page describes it as a plugin for streaming to multiple RTMP servers at the same time, and it can also share your main OBS encoder to save CPU. So you don’t need a separate paid multistream service just to test this.
I used to work around webcam studios and creator setups, but I left that space because I saw how messy and toxic a lot of it can get and people charging models for things they could learn themselves.
I still think the technical knowledge should be shared, especially because a lot of models are not super techy and small OBS things can feel way more complicated than they actually are.
The main thing you need from each site is:
- RTMP server URL
- Stream key
Every site usually has this somewhere in the broadcast/stream settings. You copy those two things into the plugin, and OBS knows where to send your stream.
Simple setup
- Install OBS if you don’t already have it.
- Download the plugin here: https://github.com/sorayuki/obs-multi-rtmp/releases
- Make sure the plugin version matches your OBS version. The latest GitHub release says the newer build is for OBS 32, and OBS 31 users should use the older 0.7.3 release.
- Install it, then restart OBS.
- After restarting OBS, look for the multi-RTMP panel/window inside OBS
- Click Docks and check Multiple Output ( thanks u/margotbabyx )
- Go to the cam site you want to add.
- Find the site’s RTMP/server settings.
- Copy the RTMP server URL and stream key.
- In the plugin, click to add a new target/output.
- Paste the RTMP URL and stream key.
- Start your normal OBS stream, then start the extra output from the plugin.
That’s basically it.
Just don’t add too many sites at once in the beginning. Start with one extra site, test if your stream is stable, then add more if your internet/PC can handle it.
Also: never share your stream key publicly, and don’t give your account login to anyone just to “help with OBS”.
If people want, I can also write a simple post on how to find RTMP settings on different cam sites.
