You can send a RadioBOSS station directly to YouTube Live using RadioBOSS’s RTMP custom encoder—no OBS or separate intermediary is required for the documented setup. YouTube supplies the RTMP server URL and stream key; RadioBOSS sends your station audio and requires a background image or video for the stream’s visual layer.
What you need before you start
- A working RadioBOSS installation and access to its Broadcast settings.
- A YouTube channel with live streaming enabled. YouTube says first-time activation may take up to 24 hours, so enable it ahead of your planned broadcast. YouTube Help: Create a YouTube live stream with an encoder
- An image or video file you have the rights to stream. RadioBOSS’s RTMP setup asks for a background visual; the manual passage does not specify exact dimensions or supported formats. RadioBOSS manual: RTMP streaming
The documented direct method uses YouTube’s RTMP endpoint and RadioBOSS’s custom encoder. The reviewed instructions do not establish a need for a new audio interface, virtual audio cable, OBS installation, or dedicated encoder. Add separate equipment or software only if you have another production requirement, such as mixing external microphones or creating a more elaborate visual scene.

Get the YouTube server URL and stream key
- Open YouTube Studio and choose Create → Go Live.
- Create a stream or select the stream you intend to use. Copy its RTMP server URL and stream key from the encoder setup in Live Control Room. YouTube’s encoder instructions explain the setup flow: Create a YouTube live stream with an encoder.
- Keep the stream key private. Anyone who obtains it may be able to send a feed to that stream. Do not include it in screenshots or publish it.
If live streaming is not available on the channel and this is your first activation, allow for YouTube’s stated possible delay of up to 24 hours. That is a maximum delay YouTube says may occur, not a typical measured wait.

Create RadioBOSS’s RTMP custom encoder
- In RadioBOSS, open Settings → Options → Broadcast → Custom Encoders.
- Add a custom encoder, give it an identifiable name such as
YT-Live, and select RTMP. - Enter the RTMP server URL and stream key copied from YouTube.
- Select the background image or video for the broadcast. Use media your station is authorized to stream.
- If RadioBOSS prompts you to install the RTMP plugin, follow the prompt. Save the RTMP settings and custom-encoder dialog.
RadioBOSS documents RTMP as a method for streaming to services such as YouTube. Its direct setup is described in the RadioBOSS RTMP streaming manual.

ZowieBox, 4K HDMI NDI Video Encoder/Decoder, HDMI NDI
- Compact but Powerful Design: ZowieBox is smaller than a phone, featuring a tally light and LCD screen for streaming status. Capture console gameplay in up to 4K with zero-lag HDMI passthrough, while the built-in video encoder converts video for IP streaming. The IP stream can also be decoded back to a 4K HDMI signal.
- Standalone Game Streaming: Just plug and play—ZowieBox enables PC-free live gaming without affecting gameplay. As an RTMP hardware encoder and HDMI streamer, it delivers stable streaming directly from your source, making it ideal for gaming, live events, and professional broadcasting.
- 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.
Add the custom encoder to Broadcast
- Open RadioBOSS’s Broadcast area and add a streaming encoder.
- Set the encoder’s Server field to
[rtmp]. - In the Encoder field, select the custom RTMP encoder you created, such as
YT-Live. - Save the Broadcast encoder settings. When you are ready to send the station, make sure this broadcast encoder is enabled or started.
Check the YouTube preview and go live
- Start the RadioBOSS broadcast output.
- Open the stream in YouTube Live Control Room and check that an incoming preview appears.
- For a scheduled stream, click Go live in Live Control Room after the preview is available. Starting the encoder feed and taking the scheduled stream live are separate actions.
- Monitor the feed in Live Control Room. When the broadcast is over, end the stream there and stop the RadioBOSS encoder.
YouTube says streams under 12 hours are automatically archived. The under-12-hour threshold is YouTube’s stated archive rule; it is not a guarantee about processing time or availability of every stream. See YouTube’s encoder setup and live-stream guidance.
Troubleshoot a missing preview
No incoming preview appears
- Check that the server URL and stream key belong to the YouTube stream currently open in Live Control Room. A key copied from another stream will send the feed elsewhere or fail to connect.
- In RadioBOSS Broadcast settings, confirm that the server is
[rtmp]and the selected encoder is the custom RTMP encoder you created. - If RadioBOSS requested the RTMP plugin, verify that it was installed, then restart or re-enable the encoder as needed.
- Confirm that the RadioBOSS output is actually started, then refresh or recheck the Live Control Room preview.
These checks follow the documented setup fields; RadioBOSS’s cited manual does not provide a list of YouTube-specific error messages.

You are following RadioBOSS Cloud instructions
RadioBOSS Cloud’s documented encoder setup uses RadioBOSS as an Icecast source with Cloud server credentials. That is a different route from sending RadioBOSS directly to YouTube over RTMP. For the direct YouTube method, use the YouTube server URL and key with the RTMP custom encoder described above. See the RadioBOSS Cloud encoder instructions and the RadioBOSS RTMP manual.
