Owncast and YouTube are separate streaming destinations, so each has its own RTMP server URL and stream key. To broadcast to Owncast, enter the Owncast endpoint and key in your encoder. To broadcast to YouTube, use the URL and key for a YouTube stream from Live Control Room. A normal encoder output aimed at Owncast does not also send the program to YouTube.
Understand which stream key goes where
The encoder sends video to a destination using that service’s server URL and stream key. Owncast’s key is for sending a broadcast to your Owncast server; YouTube’s key is for sending a broadcast to YouTube. They are not interchangeable.
Owncast’s default RTMP ingest endpoint uses TCP port 1935 and the /live path. In an encoder with separate server and key fields, the usual Owncast server value is rtmp://<owncast-host>:1935/live, with the matching Owncast stream key entered separately. Owncast also documents a full URL form that appends the key to the path: rtmp://yourserver:1935/live/<your-stream-key>.
Send an encoder to Owncast
- Find the Owncast ingest details. Sign in to the Owncast admin interface and open Configuration > Server Setup > Stream Keys. Use the key assigned to the stream you want the encoder to publish.
- Configure the encoder for a custom RTMP destination. In OBS, choose the custom service option, set the server to
rtmp://<owncast-host>:1935/live, and put the corresponding Owncast key in the stream-key field. The host must resolve to the server running Owncast and be reachable from the encoder. - Start the encoder and check the Owncast player. If the server and key match and the network path is open, Owncast should receive the broadcast. If it does not, use the troubleshooting section below to check reachability, port, URL, and credentials.
Check network access
If Owncast is behind a firewall or cloud security group, allow inbound TCP access to port 1935 for RTMP ingest. Owncast installation documentation lists port 8080 for the web interface and 1935 for RTMP ingest; opening the web interface does not by itself make the RTMP ingest port reachable.

- NDI|HX3 Converter Technology: ZowieBox converts HDMI signals to NDI|HX3/HX2/HX, functioning as an NDI video encoder, or NDI Video Decoder for flexible IP workflows. Certified NDI technology enables low-latency gameplay streaming through OBS/vMix. Note: Encoder and decoder modes cannot run simultaneously; full NDI signals are not supported.
- UVC to HDMI Conversion: Supporting up to 4K@30fps and 1080p@60fps decoding, ZowieBox enables flexible conversion for webcam and video workflows. As a video decoder and HDMI to IP converter, it expands connectivity options for professional video devices. Note: USB capture card functionality is not currently supported.
- All-around Configuration Options: Control ZowieBox through its web UI on a PC, phone, or tablet. Manage connected PTZ cameras, tally light, video/audio, OSD, work mode, streams, network, and system settings. Support for VISCA over IP encoder workflows enables flexible PTZ control, while the dashboard provides video preview and system status.
Replace default credentials
Owncast documents abc123 as an initial default stream key and admin password on its first-stream guidance. These are separate credentials. Change both immediately after setup, use a non-default stream key, and do not publish or reuse it. Owncast lets administrators manage stream keys separately and issue multiple keys.
Send an encoder to YouTube
- Open YouTube Live Control Room. In YouTube Studio, choose Create > Go Live, then create or select the YouTube stream you intend to broadcast.
- Copy the destination details for that YouTube stream. Put its server URL in the encoder’s server field and its YouTube stream key in the key field. Do not use the Owncast server URL or Owncast key for this destination.
- Start the encoder. For a scheduled YouTube stream, wait for the encoder preview to appear in Live Control Room, then click Go live there when you are ready to begin the public broadcast.
RTMP or RTMPS
YouTube describes RTMPS as RTMP protected by TLS/SSL and recommends it when the encoder supports it. Copy the RTMPS URL from Live Control Room if you choose that protocol; YouTube notes that the default displayed URL may be ordinary RTMP. Keep the protocol decision specific to each destination: Owncast’s documented ingest setup uses its RTMP endpoint, so do not substitute YouTube’s RTMPS URL for the Owncast URL.

Can one broadcast go to Owncast and YouTube?
Only if your chosen workflow supports sending to both destinations. A single ordinary encoder output configured with Owncast’s URL and key is not also configured for YouTube. Options include encoder software with simultaneous outputs or a relay service, but confirm that the specific software or service supports the required destinations and protocols before relying on it. Your upload capacity must also support the combined output path and quality.
Owncast documents a paid Restream route for a custom-RTMP destination to Owncast. That route requires a paid Restream account and publicly reachable Owncast port 1935. It is one documented option, not a requirement for every dual-output setup.

Troubleshoot connection problems
| Symptom | Likely cause | What to check |
|---|---|---|
| Owncast does not receive the broadcast | The endpoint is unreachable, the RTMP port is closed, or the server address is wrong. | Confirm the host name or address, the /live path, and inbound TCP port 1935 on the Owncast host’s firewall or cloud security group. |
| The encoder reports an authentication or connection error | The key may belong to the other service, may be mistyped, or may no longer be valid. | Copy the Owncast key from its admin stream-key settings for an Owncast output; copy the YouTube key from Live Control Room for a YouTube output. Keep each key paired with its own server URL. |
| YouTube shows no preview after encoding starts | The encoder may be using the wrong YouTube stream details or protocol. | Verify the selected stream in Live Control Room and recopy its server URL and key. If using RTMPS, use the RTMPS URL shown there rather than assuming the default URL is encrypted. |
| YouTube preview appears, but the scheduled stream is not live | The encoder preview has arrived, but the operator has not started the scheduled broadcast in YouTube. | When ready, click Go live in Live Control Room. |
| Video stalls or the server struggles under load | The selected output quality may exceed the available server or network capacity. | Reduce the encoder’s output demand and check the Owncast server’s capacity and network. Owncast notes that higher resolution or bitrate can add conversion work and resource use; the cited setup guidance does not specify a universal bitrate or resolution for every server. |
