StreamLive ProStream from a YoloBox to several networks at once
Add StreamLive Pro as a custom RTMP(S) platform on a YoloBox, YoloBox Pro or Ultra and reach every network from one stream: the emailed link, the fields, and fixes.
A YoloBox streams to the platforms you add on its Platform tab, and one of them can be a custom RTMP(S) destination. Add StreamLive Pro there, with the address and the stream key from the Encoder card, and the box sends one stream that StreamLive Pro passes on to every channel you tick. On most models you enter the address and key through a link the box emails you; the YoloBox Ultra can also take them directly.
The YoloBox steps follow YoloLiv's own article, YoloLiv: How to live stream with RTMP(s) on YoloBox, YoloBox Pro and YoloBox Ultra, checked 5 November 2026. Menu names can change with the box's firmware.
Before you start
- A paid StreamLive Pro plan. Receiving a stream from a hardware encoder is on the paid plans; the 7-day trial streams from the browser studio. See the pricing page.
- The e-mail account of the YoloBox at hand, for the setup link.
- Channels connected under Connections. Instagram and TikTok need a new key before every live (Live on Instagram and TikTok with a stream key).
Steps
- Open the Encoder card. In StreamLive Pro click New stream and choose Stream from software like OBS (RTMP / SRT). Open the RTMPS tab, or the RTMP tab if you prefer, and keep the card open to copy the address and the key.
- Create a live event on the YoloBox. On the box, create the event you are going to stream.
- Add a custom platform. Go to the Platform tab, tap the add button and choose RTMP(S). The screen Add a Custom RTMP(S) Destination opens.
- Send yourself the link. Tap Send the Link. An e-mail with the subject Custom RTMP arrives; if it does not, check the spam and promotions folders.
- Enter the address and key. Open the link from the e-mail on the computer where StreamLive Pro is open. Paste the address into Server URL and the key into Stream Key, and name the platform StreamLive Pro. Tap Send; a message confirms it. On a YoloBox Ultra you can instead tap Fill In Manually on the box and paste the details there.
- Switch the platform on. Back on the box, StreamLive Pro appears on the Platform tab. Turn its switch on, and switch off other platforms you added directly, so the box sends only to StreamLive Pro.
- Tick your channels in StreamLive Pro 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.
- Go live on the box. Within about ten to thirty seconds StreamLive Pro shows that the stream was detected. To finish, press Stop stream in StreamLive Pro to end on every network, then stop the box.
Why one platform on the box instead of several
The YoloBox can stream to several platforms itself, and each one is a separate upload over the box's own connection, often a phone SIM or a venue's Wi-Fi. Sending one stream to StreamLive Pro keeps the box's upload at one stream, which matters most on mobile data, and our servers make the copies for each network. You also give each network its own title (Give each network its own title in one live broadcast) and see YouTube and Facebook comments in one chat.
Settings that matter
Our ingest accepts H.264 video and AAC audio, a combined bitrate between 2 and 14 Mbps, and a keyframe interval between 2 and 10 seconds (Cloudflare Stream: Start a live stream, checked 5 November 2026). If the box offers a choice of video codec, choose H.264. On mobile data, pick a lower quality, because one stalled upload stalls every network at once; Upload speed and bitrate for multistreaming shows the arithmetic.
What we have not checked
We have not tested a specific YoloBox model or firmware against StreamLive Pro. YoloLiv's article does not state the codec, the bitrate or the keyframe interval the box sends, or how many platforms each model streams to at once. Run a test with one unlisted YouTube channel before an event, over the same connection you will use on the day.
What can go wrong
| Symptom | Fix |
|---|---|
| The setup e-mail does not arrive | Check spam and promotions; check the box's network connection |
| The link page will not save | YoloLiv suggests another browser, such as Safari, Edge or Firefox |
| The box connects but StreamLive Pro sees nothing | Server URL and Stream Key swapped, or a key from another broadcast. Enter them again |
| The box streams, the networks are empty | The Live stream page was closed or in the background, or no channel was ticked. See OBS is streaming, but YouTube and Facebook show nothing |
| Detected, no picture | See My encoder says it is streaming, but there is no picture |
| Stutters on every network on mobile data | The bitrate is above what the SIM holds. Lower the quality |
Frequently asked questions
Can a YoloBox stream to YouTube and Facebook at the same time through StreamLive Pro?
Yes. The box sends one stream to StreamLive Pro, and our servers send it to YouTube, your Facebook Page and every other channel you ticked.
Why does the YoloBox e-mail me a link?
On most models the address and key are entered through a link the box sends by e-mail, which is easier than typing a long key on the box. The YoloBox Ultra also has Fill In Manually.
Which StreamLive Pro tab do I use for a YoloBox?
The box's platform is called RTMP(S), so the RTMPS tab is the natural choice. If it does not connect, try the RTMP tab.
Does sending through StreamLive Pro save mobile data?
Yes, compared with sending a separate stream to each network from the box. The box uploads one stream whatever the number of networks.
Can I use a YoloBox during the StreamLive Pro trial?
No. Streaming from a hardware encoder is on the paid plans. The trial streams from the browser studio.
