You can create a YouTube Live feed from a still image and repeating music with FFmpeg by looping both inputs, pacing playback in real time, and sending an H.264/AAC stream to the RTMPS address and stream key for your YouTube broadcast. The command below is a starting point, not a tested or guaranteed 24/7 service: you must choose the output resolution, test the feed in YouTube Studio, and plan for process or network failures.
What you need before starting
- A still image and music file that FFmpeg can read, with permission to use and stream both.
- An installed FFmpeg build that supports the required input options, H.264 video encoding, AAC audio encoding, and RTMPS output. Check it with
ffmpeg -version; option and codec availability can vary by build. - A YouTube channel able to go live, with an encoder-based stream created in YouTube Studio.
- A stable upload connection that can sustain the chosen video and audio bitrates, with room for network variation.
Use YouTube’s live stream settings guide to create or schedule an encoder-based stream in Live Control Room. Copy the RTMPS ingestion URL and the stream key YouTube gives that stream. Google’s LiveStreams API resource refers to these as the ingestion address and stream name. Use the supplied values rather than guessing a generic endpoint.
Choose resolution, bitrate, and keyframe interval
The example uses 30 frames per second and a nominal two-second GOP. At 30 fps, -g 60 sets 60 frames between keyframes. YouTube’s current encoder guidance recommends a two-second keyframe frequency and says not to exceed four seconds. Set the output dimensions deliberately: without a scale filter, the image’s dimensions determine the video dimensions, so the command does not automatically produce 720p.
| Output target | YouTube bitrate guidance | Practical note |
|---|---|---|
| 480p at 30 fps | 0.3–3 Mbps | Choose a bitrate your connection can sustain. |
| 720p at 30 fps | 2–6 Mbps | The example uses 2.5 Mbps, within this recommended range. |
These ranges are YouTube recommendations, not guarantees of picture quality or viewer reach. YouTube also recommends 44.1 kHz audio and 128 kbps stereo audio. Its settings can change; check the current encoder settings, bitrates, and resolutions before a long-running setup.

Build the FFmpeg command
Replace image.jpg and music.mp3 with your file paths, then replace the RTMPS placeholders with the exact address and key from YouTube. Keep the working key private: it functions as a credential that allows an encoder to send video to your stream.

Set a different image size
If your image is not already at the dimensions you want, add a scale filter to the video options. For example, to target 1280 × 720, add -vf "scale=1280:720" before the video codec options. Scaling may change the image’s aspect ratio if its proportions do not match 16:9. To preserve proportions and fit within 1280 × 720, use a scale expression such as -vf "scale=1280:720:force_original_aspect_ratio=decrease,pad=1280:720:(ow-iw)/2:(oh-ih)/2". Confirm that your FFmpeg build accepts the filter and inspect the preview for cropping, padding, or distortion.
Protect the stream key
Do not publish the complete command with an active key, leave it in a shared log, or include it in a screenshot. YouTube describes the key as password-like; if it is exposed, reset it in the stream settings and update your FFmpeg destination with the replacement. RTMPS encrypts the connection in transit, but that does not make a disclosed key safe. YouTube recommends RTMPS for this workflow; see its RTMPS ingestion guide.

Start the YouTube broadcast and verify the feed
- In YouTube Studio, create or schedule an encoder-based live stream in Live Control Room.
- Copy the RTMPS URL and stream key for that stream into the FFmpeg command. YouTube’s encoder settings identify RTMP/RTMPS ingestion and compatible video and audio codecs.
- Run FFmpeg on the computer or server hosting the media files. Watch its output for connection or encoding errors.
- Check the Live Control Room preview and stream health. Confirm that the image appears, music is audible, and the stream reports no actionable health messages.
- Test privately or as unlisted before promoting the stream. Start or confirm the broadcast according to the controls and settings shown for your stream.
Keep the YouTube concepts distinct: the incoming liveStream is the feed/configuration, while the liveBroadcast is the viewer-facing event. Google’s guide, Understanding Broadcasts and Streams, describes a channel using a 24/7 live feed alongside a separate event broadcast. A continuously running FFmpeg process does not by itself guarantee that one viewer-facing broadcast or archive behaves as you expect.
What it takes to keep the feed running 24/7
Looping media and pacing input solve only the playback side. FFmpeg can stop because of a process error, a damaged or unreadable file, a power outage, or a network interruption. YouTube recommends test runs and monitoring; its live streaming tips cover preparation, and its health status messages reference issues such as low bitrate, GOP length, unsupported audio, or missing and inconsistent streams.

- For a machine you manage, use a process supervisor configured to restart FFmpeg after an unexpected exit, and retain logs so you can diagnose repeat failures.
- Monitor the YouTube preview and health messages, as well as the host’s power and network connection. A restart policy cannot fix a persistent network outage or invalid media.
- FFmpeg’s all-options documentation includes an RTMP FIFO muxer example that attempts recovery after temporary network failure. Treat it as an option to investigate, not an uninterrupted-service guarantee; exact options and RTMPS compatibility depend on the build and configuration. See FFmpeg’s all-options documentation.
These operational measures are general engineering practices, not uptime guarantees from FFmpeg or YouTube. No command can promise an uninterrupted 24/7 broadcast.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Preflight and troubleshooting
Before you go live
- Open both input files and verify the audio contains usable sound.
- Check the installed FFmpeg version and confirm the needed loop options, encoders, and output protocol are available.
- Choose the output dimensions and frame rate; do not assume the image will become a standard resolution automatically.
- Use YouTube-compatible codecs and a keyframe interval that does not exceed four seconds; YouTube recommends two seconds.
- Select a bitrate your upload can sustain, run a test, and inspect stream health.
- Use the actual RTMPS URL and key from Live Control Room, and keep the key secret.
- Confirm you are authorized to stream the image and music and that the content complies with YouTube’s Community Guidelines. The applicable rights depend on the particular files and permissions; platform technical settings cannot determine them for you.
Common problems and fixes
| Symptom | Likely cause | What to check |
|---|---|---|
| YouTube does not receive a feed | Incorrect URL or key, connection failure, or unsupported output configuration. | Copy the exact values for the stream from Live Control Room, inspect FFmpeg’s error output, and verify RTMPS support in your build. |
| Video appears at the wrong size | The command uses the image’s dimensions because no scale filter is specified. | Inspect the image dimensions and add an appropriate scale filter; check aspect ratio and preview framing. |
| The music ends or does not repeat | The audio input path, format, or looping option is incorrect. | Confirm FFmpeg can read the file and that -stream_loop -1 precedes that input. |
| Audio is silent or YouTube flags audio | The file may lack usable audio, or its codec/settings may not match the intended output. | Test the source file, then check AAC encoding, sample rate, and YouTube’s current audio guidance. |
| YouTube reports poor stream health | Bitrate may be too low or unstable, the keyframe interval may be unsuitable, or audio/video may be unsupported or inconsistent. | Read the specific health message, verify settings against YouTube’s encoder guidance, and test with a sustainable bitrate. |
| The stream stops after initially working | FFmpeg exited, the host lost power or connectivity, or YouTube stopped receiving the feed. | Inspect logs and host/network status, restart the process if needed, and configure supervision and monitoring for unattended operation. |
