StreamLive ProConnect XSplit Broadcaster to StreamLive Pro
Add a Custom RTMP output in XSplit Broadcaster with StreamLive Pro's address and key, and reach YouTube, Facebook Pages, Twitch and more from one stream: steps and fixes.
XSplit Broadcaster streams to any server through a Custom RTMP output. Create one with the address and the stream key from StreamLive Pro's Encoder card, and XSplit sends one stream that StreamLive Pro passes on to every channel you tick: YouTube, Facebook Pages, Twitch, Kick, LinkedIn by key, a custom server. Your computer uploads that one stream, not one per network.
The XSplit steps follow XSplit's own article, XSplit Support: Setting up Custom RTMP for different platforms, checked 5 November 2026.
Before you start
- A paid StreamLive Pro plan. Receiving a stream from other software is on the paid plans; the 7-day trial streams from the browser studio. See the pricing page.
- Channels connected under Connections. Instagram and TikTok need a new key before every live (Live on Instagram and TikTok with a stream key).
- XSplit Broadcaster with your scene ready.
Steps
- Open the Encoder card. In StreamLive Pro click New stream and choose Stream from software like OBS (RTMP / SRT). Open the RTMP tab and copy the address and the stream key.
- Create the output in XSplit. Open the Broadcast menu, choose Set up a new output, then Custom RTMP. The properties window opens.
- Name it. In Name type something you will recognise in the Broadcast list, for example StreamLive Pro.
- Paste the address. Paste the StreamLive Pro address into RTMP URL.
- Paste the key. Paste the key into Stream Key. XSplit's article notes that when a service gives one long URL with the key at the end, the key goes in Stream Key and not in the URL; StreamLive Pro's card already gives them separately. Leave the optional fields as they are, then click OK.
- Tick your channels in StreamLive Pro. Switch on the destinations in the Channels list and keep the Live stream page open and in front. It checks for your stream every ten seconds and sends it out when it arrives.
- Start the broadcast in XSplit. Open Broadcast and choose the StreamLive Pro output. Within about ten to thirty seconds StreamLive Pro shows that the stream was detected.
- End from StreamLive Pro. Press Stop stream to end on every network, then stop the output in XSplit.
Encoder settings for XSplit
XSplit's article leaves the encoding to the output's own settings. Set them to what our ingest accepts:
| Setting | Value |
|---|---|
| Video | H.264 |
| Audio | AAC, 128 kbps stereo |
| Bitrate | Between 2 and 14 Mbps for video and audio together, within your upload |
| Keyframe interval | 2 seconds |
| Rate control | Constant bitrate (CBR) if offered |
Sources: Cloudflare Stream: Start a live stream for the codecs, bitrate range and keyframes, YouTube Help: live encoder settings for the audio and the 2-second keyframes, both checked 5 November 2026. The same reasoning as for OBS applies; see OBS settings for multistreaming to several networks.
One output in XSplit, many networks
XSplit lets you create several outputs, one per service, and each output you run is a separate upload from your line. With StreamLive Pro you run a single output. Our servers make the copies, give each network its own title (Give each network its own title in one live broadcast), and gather YouTube and Facebook comments into one chat. The difference in upload is worked out in Upload speed and bitrate for multistreaming.
What we have not checked
We have not tested a specific XSplit version against StreamLive Pro, and the XSplit article does not say whether its Custom RTMP output accepts rtmps:// addresses, so this page uses the RTMP tab. Before an important show, run a test with one unlisted YouTube channel ticked.
What can go wrong
| Symptom | Fix |
|---|---|
| XSplit cannot connect | RTMP URL and Stream Key swapped, or a trailing space. Copy both again |
| Connects at home, not at the venue | Port 1935 is blocked there. Try another network, or the RTMPS tab if your XSplit accepts rtmps:// |
| XSplit is live, the networks are empty | The Live stream page was closed or in a background tab, or no channel was ticked. See OBS is streaming, but YouTube and Facebook show nothing |
| Detected, no picture | HEVC selected, or keyframes too far apart. See My encoder says it is streaming, but there is no picture |
| The Encoder card shows "On paid plans" | The account is in the trial |
Frequently asked questions
Can XSplit stream to YouTube and Facebook at the same time through StreamLive Pro?
Yes. XSplit sends one Custom RTMP output to StreamLive Pro, and our servers send it to YouTube, your Facebook Page and every other channel you ticked.
Where is Custom RTMP in XSplit?
In the Broadcast menu, under Set up a new output, then Custom RTMP.
Which fields do I fill in XSplit?
Name, RTMP URL with the StreamLive Pro address, and Stream Key with the key. The other fields are optional.
Can I use XSplit during the StreamLive Pro trial?
No. Streaming from other software is on the paid plans. The trial streams from the browser studio.
Do I need a separate XSplit output for each network?
No. One output to StreamLive Pro is enough; tick the networks in StreamLive Pro.
