Copy the stream URL and key for your sermon event from YouTube Studio’s Live Control Room, then use them as FFmpeg’s publishing destination. The URL routes the feed to YouTube; the key authorizes it. Use YouTube’s RTMPS URL when available, keep the key private, and test the complete video and audio feed in Live Control Room before the service.
Before you configure FFmpeg
- Your channel must be eligible to livestream: YouTube requires channel verification, no live-streaming restriction in the previous 90 days, and that the streamer be at least 16. Check the current requirements in YouTube’s live-streaming help.
- Install an FFmpeg build that supports your chosen input, video and audio codecs, and RTMPS/TLS if you plan to use RTMPS. Available support depends on how FFmpeg was built.
- Have the sermon video or live audio/video input ready, and test the internet connection from the machine that will run FFmpeg.
Get the correct YouTube stream URL and key
- In YouTube Studio, select Create → Go live to open Live Control Room.
- Create a stream for the service or select its scheduled event. In the Stream tab, copy the server URL and stream key shown for that stream.
- Use the URL and key together. Prefer the RTMPS server URL if YouTube provides it; do not assume that an RTMP URL and an RTMPS URL are interchangeable. YouTube describes stream keys as “like your YouTube stream’s password and address” in Manage live stream settings.
You may use a custom stream key again where YouTube permits, but make sure it is the one associated with the stream configuration you intend to send to. Treat it as a credential: do not put it in a public command transcript, screenshot, shared document, or repository. If it may have been exposed, reset it in Live Control Room and replace the old value in FFmpeg.
Put the key in FFmpeg’s output destination
FFmpeg sends the encoded feed to an output URL. The general RTMP form shown in the FFmpeg protocol documentation is rtmp://server/app/playpath; YouTube supplies the actual server URL and key for your stream. Combine the values according to the server URL’s path structure, using the stream key as the publishing key portion.
ffmpeg -re -i INPUT -c:v libx264 -preset veryfast -b:v 2500k -c:a aac -b:a 128k -f flv 'rtmp://SERVER/APP/STREAM_KEY'This is a schematic example, not a tested command or a universal quality preset. Replace INPUT with your source, and replace the destination placeholders with the server and key from Live Control Room. If YouTube gives you an RTMPS URL, use that exact URL and the matching key rather than copying the example’s rtmp:// scheme. FFmpeg documents RTMPS as RTMP over SSL/TLS in its RTMPS protocol notes.

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.
For a real service, use the command-line options that match your input and YouTube’s current encoder guidance. The sample’s 2,500 kb/s video rate is illustrative only; it is not a recommendation for every resolution, frame rate, or codec.
Choose settings for the sermon feed
YouTube’s current live encoder settings, bitrates, and resolutions distinguish recommendations by codec and resolution. For ordinary SDR RTMP/RTMPS, YouTube lists H.264, H.265, or AV1 video and AAC or MP3 audio, recommends CBR, supports up to 60 fps, and recommends a two-second keyframe interval (no more than four seconds). Consult its current table for the bitrate range that matches your chosen codec, resolution, and frame rate instead of copying an arbitrary value.

Backed by a 1-year warranty and 24/7 online technical support.
- Resolution and frame rate: Set them to match the camera or source and the quality you can reliably upload. Higher resolution and frame rate require more bandwidth.
- Video and audio codecs: Choose a supported combination from YouTube’s current table and ensure the FFmpeg build includes the encoders you specify.
- Bitrate and rate control: Follow the table for the chosen output and use CBR as YouTube recommends for this setup.
- Keyframes: Set a two-second interval if your encoding configuration exposes that option; do not exceed YouTube’s four-second maximum recommendation.
- Upload headroom: YouTube recommends leaving 20% of upload capacity unused. Account for a backup stream as well if you are sending one.
Start early and verify the stream
- Start FFmpeg far enough before the service to diagnose connection, picture, and sound issues.
- Open the event’s Live Control Room and check its preview and stream health. Confirm that the picture moves, speech is audible, and there is no unexpected silence, clipping, or delay that would disrupt the service.
- Run a test with motion and audio similar to the actual sermon, and confirm the available upload bandwidth has headroom for the selected bitrate. YouTube’s encoder guidance recommends 20% unused upload capacity.
- Check that the event’s watch page is accessible to its intended audience before the service begins.
- At the end, stop FFmpeg and end the event in Live Control Room as appropriate. YouTube says streams shorter than 12 hours are automatically archived; do not assume that applies to a stream lasting 12 hours or longer.
Troubleshoot common connection problems
| Symptom | Likely cause | What to check |
|---|---|---|
| YouTube does not receive a feed | The key, server URL, or path does not match the selected stream, or FFmpeg cannot reach the ingest server. | Copy the current URL and key from that event’s Live Control Room, verify the output destination, and check the FFmpeg error output and network access. |
| RTMPS fails with an SSL or TLS error | The connection may be using an unsuitable port or the FFmpeg build may lack suitable RTMPS/TLS support. | With the correct RTMPS URL, YouTube says to try port 443. If the connection still fails, confirm the build’s RTMPS/TLS support; use the current Live Control Room details. |
| The feed connects but picture or sound is wrong | The input mapping, selected codecs, or output settings may not match the source or YouTube’s guidance. | Inspect the FFmpeg input and output options, then compare codec, resolution, frame rate, keyframe interval, and bitrate with YouTube’s current encoder table. |
| The stream is unstable or YouTube reports poor health | The connection may lack upload headroom for the configured bitrate, or the source may be inconsistent. | Measure the connection from the encoder machine, leave the recommended 20% upload capacity unused, and test with service-like motion and audio. Include any backup stream in the bandwidth calculation. |
| The key may have been shared or exposed | Anyone with the key may be able to attempt to publish to the channel’s stream configuration. | Reset the key in Live Control Room, update FFmpeg to use the new key, and avoid sharing command output that contains it. |
