Stream to a custom RTMP or SRT server

Stream to any custom RTMP, RTMPS or SRT server from StreamLive Pro: add the address and key once, tick it next to YouTube and Facebook, and go live.

Updated November 5, 2026 · 4 min read

Any service or server that gives you an RTMP, RTMPS or SRT address can be a destination of your broadcast. Add it once on the Connections page with the Custom RTMP or Custom SRT card, paste the address and the key, and from then on tick it in the channel list like any network. StreamLive Pro sends a copy of the broadcast to it from our servers, together with YouTube, Facebook and the rest. WHIP and HLS addresses are not supported as destinations.

Before you start

• The address and key from the receiving side. A streaming service shows them in its stream or encoder settings, usually as a server URL and a stream key. Your own server's admin can give them to you.
• A public address. The copy is sent from our servers over the internet, so the server must be reachable from the internet. Addresses on a private network, such as 127.0.0.1 or 192.168.x.x, are refused.
• A supported protocol. The address has to start with rtmp://, rtmps:// or srt://. If the service offers both, rtmps:// is RTMP over an encrypted connection. The differences are explained in RTMP vs RTMPS vs SRT: which one to use and when.
• Check for a ready-made card first. Many services already have their own card on Connections, for example Rumble, Vimeo Live, Dailymotion Live, VK Video Live, Trovo, DLive, Odysee, Bilibili Live, Huya and Steam Broadcasting. Those cards check that the address belongs to the service, which catches a wrong paste before you go live. Use Custom RTMP for everything else.

Steps

1. Open the custom cards. Open Connections and scroll to Custom destinations, below the networks that work with a stream key.
2. Choose the card. Click Custom RTMP for an rtmp:// or rtmps:// address, or Custom SRT for an srt:// address.
3. Fill in the fields. Display name is optional; it is how the destination appears in your channel list, for example "Website player". Paste the server address in the URL field and the key in the Stream Key field. For SRT, paste the full address exactly as your server gives it, including the streamid part if it has one.
4. Save. Click Save connection. If the same address and key were already saved, the existing destination is updated instead of a duplicate being made.
5. Tick it and go live. On Live stream, tick the destination in the Channels list together with any networks, and press Start stream. It counts as one destination of the broadcast, like any network.
6. Check the receiving side. Open the service's dashboard or your server's player and confirm the picture arrives.

Good to know

• One upload from you. Your computer sends one stream to StreamLive Pro. The copy to your server is made on our side, so adding a destination does not add load on your connection. See Upload speed and bitrate for multistreaming.
• The same address twice. If two destinations of one broadcast have the same address and key, only one copy is sent.
• Sending into StreamLive Pro is a different thing. This page is about where the broadcast goes. To send from OBS, vMix or a hardware encoder into StreamLive Pro over RTMP or SRT, see Connect OBS to StreamLive Pro and multistream and Stream with SRT from OBS, vMix or a hardware encoder.
• WHIP and HLS. Some text on the Connections page still mentions WHIP and HLS. As destinations they are refused with a message, because broadcasts leave our servers only over RTMP, RTMPS or SRT. If your service also offers an RTMP or SRT address, use that.

What can go wrong

Test a new custom destination with a short private broadcast before an important event.

Frequently asked questions

Can I restream to my own RTMP server?

Yes, if it has a public address. Add it with the Custom RTMP card and tick it in the channel list next to your other networks.

Does StreamLive Pro support SRT as a destination?

Yes. Use the Custom SRT card and paste the full srt:// address your server gives you, including the streamid part if it has one.

Can I send to a server on my local network?

No. The copy is sent from our servers over the internet, and private addresses such as 192.168.x.x are refused. The server needs a public address.

Can I add a WHIP or HLS destination?

No. Broadcasts leave StreamLive Pro over RTMP, RTMPS or SRT only. If your service offers an RTMP or SRT address, use that.

Does a custom destination count toward my plan?

Yes. Each ticked destination counts as one of the destinations your plan allows in a single broadcast.

Will this use more of my upload?

No. You upload one stream to StreamLive Pro, and the copy to your server is sent from our side.
