Use an encoder such as OBS Studio to pair a still image with your MP3 audio, then send the combined video-and-audio stream to YouTube Live over RTMPS. The image must be encoded as the video part of the broadcast; uploading audio alone is not enough. Before going live, confirm you have rights to rebroadcast every episode and test that the audio plays, the image appears, and YouTube reports healthy stream status.
What you need before you start
- A YouTube channel set up for live streaming and access to YouTube Live Control Room.
- An encoder such as OBS Studio, installed on a computer that can remain on and connected for the broadcast.
- The MP3 files in the order you want them played, plus one image to represent the show.
- A reliable upload connection capable of sustaining the bitrate you choose for your video resolution.
- Permission to rebroadcast all audio in the archive, including music, guest recordings, and inserted clips.
Previously published podcast episodes are not automatically cleared for a new live rebroadcast. YouTube scans live streams for matches to third-party content; a match can replace the stream with a placeholder image or interrupt or terminate the broadcast. If you have a license, check whether the rights holder must add your channel to its Content ID allowlist. YouTube’s live-stream copyright guidance explains these actions.
Build the broadcast in OBS
- Create a scene. In OBS Studio, add a scene for the podcast stream. Add your still image as an image source and size or crop it to fit the canvas. The encoder must keep rendering this image as video for the duration of the stream.
- Add the MP3 playback. Add or route audio playback into the scene using a method supported by your OBS setup. Arrange the episodes in the intended order and set playback or playlist behavior to match whether you want the archive to play once or repeat. Playlist and looping controls vary by software version and setup; confirm the behavior in your installed version rather than assuming a particular control or menu path.
- Choose YouTube as the destination. In OBS’s streaming settings, select YouTube – RTMPS, then select or enter the stream key for the intended broadcast. OBS’s setup guide covers connecting OBS to YouTube; interface labels may change. See OBS’s YouTube streaming guide.
- Configure video and audio output. Use a YouTube-supported video codec—H.264, H.265/HEVC, or AV1—and AAC or MP3 audio. Set rate control to CBR and the keyframe interval to 2 seconds; YouTube says not to exceed 4 seconds. For stereo, YouTube lists 44.1 kHz and recommends 128 Kbps audio. Choose the video resolution and corresponding bitrate from YouTube’s current encoder settings, taking your upload capacity into account.
- Use secure ingest. YouTube recommends RTMPS. Its ingestion documentation specifies an RTMPS ingestion URL and port 443. If you are configuring a custom encoder rather than using OBS’s YouTube destination, use the valid ingest endpoint and connection details supplied for that integration. Read Google’s RTMPS ingestion guidance.
Test the stream before the audience depends on it
- Keep the stream key private; treat it like a password.
- Start a private or unlisted test broadcast if that fits your channel’s workflow.
- Check the YouTube preview for the still image and confirm the audio is audible.
- Let the archive run long enough to verify that tracks advance in the intended order and repeat—or stop—according to your plan.
- Check YouTube Live Control Room’s stream health indicators. A successful connection from OBS does not by itself mean the broadcast has been made live to viewers.
YouTube recommends testing before starting and monitoring stream health during the broadcast. Its preflight guidance covers representative audio and movement; for this still-image format, verify the image and representative audio instead. YouTube’s encoder settings page includes its testing and monitoring advice.
Go live, monitor, and end the broadcast
Start the encoder stream and check the status in Live Control Room. Scheduled-stream behavior and auto-start settings can affect when viewers can watch, so confirm the broadcast is actually live rather than relying on the encoder’s connection indicator. Monitor stream health and audio during playback. When the archive is finished, stop the stream in OBS and confirm in Live Control Room that the broadcast has ended. OBS documents the basic controls in its YouTube streaming guide.

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.
Common problems and fixes
- YouTube preview has no image: Check that the image source is visible in the active OBS scene and fits the canvas. Confirm OBS is sending video, not only audio.
- YouTube preview has no sound: Check the MP3 source or playback route, OBS audio meters, and mute controls. Verify the output audio codec and channel configuration.
- The encoder connects but viewers cannot watch: Check Live Control Room and the scheduled stream’s start or auto-start behavior; an encoder connection is not proof that the public broadcast is live.
- Stream health warns of connection or bitrate trouble: Compare the selected resolution and bitrate with YouTube’s current table and your available upload connection. Use CBR and the recommended 2-second keyframe interval, and test again.
- The archive stops or tracks do not advance: Review the playback and playlist behavior in your installed encoder setup. These controls are version-dependent; verify the sequence and repeat behavior in a test stream before relying on it.
- YouTube interrupts the broadcast or replaces the image: A third-party-content match may have been detected. Review the archive’s rights, and if the material is licensed, ask the rights holder whether your channel needs a Content ID allowlist entry.
