Connect Streamlabs Desktop to StreamLive Pro

Connect Streamlabs Desktop to StreamLive Pro with Stream to Custom Ingest: where the URL and key go, the output settings, what stops working, and the fixes.

Updated November 5, 2026 · 4 min read

Streamlabs Desktop can send its stream to StreamLive Pro through its custom ingest option. In Streamlabs you set the stream type to Custom Streaming Server and paste the address and the key from the Encoder card on the Live stream page. StreamLive Pro then sends that one stream to every channel you ticked, so Streamlabs only uploads it once.

The general rules for every encoder are in Connect Streamlabs, Larix or a hardware encoder by RTMP. This page goes through Streamlabs Desktop itself, including what Streamlabs says stops working when you use a custom server.

Before you start

• A paid plan. Encoder ingest is on the paid plans. In the 7-day trial the Encoder card shows that RTMP and OBS are on paid plans instead of an address, and the trial streams from the Browser Studio. See the pricing page.
• Connected channels under Connections. Instagram and TikTok need a fresh key before every live (Live on Instagram and TikTok with a stream key).
• Streamlabs Desktop installed and signed in. The menu names below are from Streamlabs' own article (Streamlabs: How to stream to a new platform with custom ingest, checked 5 November 2026).

Steps

1. Open the Encoder card. In StreamLive Pro click New stream and choose Stream from software like OBS (RTMP / SRT). The Live stream page opens on the Channels tab, with the Encoder card under the preview.
2. Choose the tab and copy. Start with the RTMPS tab: it is encrypted and runs on port 443. Copy the address with its copy button, then copy the key with its own button. Do not reveal the key on screen.
3. Open the stream settings in Streamlabs. Click Settings in the top-right corner of Streamlabs Desktop and select Stream in the left sidebar.
4. Switch to custom ingest. At the bottom of the screen click Stream to Custom Ingest, and set Stream Type to Custom Streaming Server.
5. Paste the address and the key. Paste the address into the URL field and the key into Stream Key, then click Done.
6. Check the output. In Streamlabs' output settings use the same values as for OBS: an H.264 encoder (not HEVC or AV1), constant bitrate, keyframe interval 2, AAC audio. The reasons and bitrate choices are in OBS settings for multistreaming to several networks.
7. Tick your channels. Back in StreamLive Pro, switch on each destination in the Channels list and keep the page open.
8. Go live in Streamlabs. Within about ten to thirty seconds StreamLive Pro shows that the stream was detected and sends it to the ticked channels. To finish, press Stop stream in StreamLive Pro first, then end the stream in Streamlabs.

What changes when Streamlabs streams to a custom server

Streamlabs' article lists what stops working with a custom ingest, because the destination is not one of its built-in platforms:

• Chat does not appear in the Streamlabs side dock.
• Alerts and widgets do not update or show up.
• Title and description have to be set on the platform itself.
• Streamlabs Support cannot help with custom sites.

In StreamLive Pro, the chat of YouTube and Facebook appears next to the player on the Live stream page, with replies on both (Live chat from YouTube and Facebook in one panel). Titles and descriptions per network are set in StreamLive Pro before you go live.

RTMPS or RTMP

Use the RTMPS address when you can. Streamlabs' article does not say whether its custom ingest accepts rtmps:// addresses, and we have not tested every Streamlabs version. If Streamlabs cannot connect with the RTMPS address, switch to the RTMP tab in StreamLive Pro, copy that address, and try again. The key stays the same for both tabs of the same broadcast. The difference between the two is explained in RTMP vs RTMPS vs SRT: which one to use and when.

One destination in Streamlabs

Keep StreamLive Pro as the only destination in Streamlabs and choose the networks in StreamLive Pro. If a network is also set up inside Streamlabs, that network can receive two copies of the show, and your upload carries the extra one. Your upload need does not grow with the number of networks you tick in StreamLive Pro; the arithmetic is in Upload speed and bitrate for multistreaming.

Frequently asked questions

Can I use Streamlabs Desktop with StreamLive Pro?

Yes, on a paid plan. Choose Stream to Custom Ingest, set Custom Streaming Server, and paste the address and key from the Encoder card.

Where is the custom server option in Streamlabs?

In Settings, Stream. At the bottom of that screen click Stream to Custom Ingest and set Stream Type to Custom Streaming Server.

Why does my Streamlabs chat stop working?

Streamlabs says chat, alerts and widgets do not work with a custom ingest. Read and answer YouTube and Facebook chat on the Live stream page in StreamLive Pro instead.

Should I use RTMP or RTMPS in Streamlabs?

Try RTMPS first. If Streamlabs will not connect, use the RTMP address from the same Encoder card; the key does not change.

Can I use Streamlabs during the trial?

No. Encoders are on the paid plans. The 7-day trial streams from the browser studio.
