1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsYou can loop a local video into YouTube Live from Linux with FFmpeg: give FFmpeg the stream URL and key from YouTube Live Control Room, then use -stream_loop -1 to repeat the file and -re to send it at its media rate. The script below is a starting point; test it with a private event and adjust its encoding settings for your source and upload connection.
What you need before starting
- A Linux computer or server with FFmpeg installed and a reliable internet connection. The computer running FFmpeg must stay on and connected for the stream to continue.
- A local video file you have the right to stream.
- A YouTube channel eligible to livestream. YouTube says channels must be verified, have no live-streaming restrictions in the previous 90 days, and be operated by someone at least 16 years old. Check YouTube’s current live-streaming eligibility guidance.
Install FFmpeg through a trusted source for your Linux distribution, then check the installed build with ffmpeg -version. Available encoders vary by build; the example below requires the libx264 video encoder.
Get the YouTube stream URL and key
- Open YouTube Studio and enter Live Control Room. Create a stream or select a scheduled stream.
- Copy the server URL and stream key shown for that stream. Use the URL format displayed for your selected key; do not assume that every account or endpoint has the same format. YouTube recommends RTMPS for secure ingest. See Create a YouTube live stream with an encoder.
- Keep the key private. YouTube Help says, “Stream keys are like your YouTube stream’s password and address.” If it is exposed, reset it in YouTube Studio and update the encoder. See Manage live stream settings.
Write and run the Linux loop script
Save this as youtube-loop.sh. It reads the video path as its first argument, or uses loop.mp4 if you omit one. It expects the RTMPS server URL and stream key to be supplied as environment variables rather than written into the script.
#!/usr/bin/env bash
set -euo pipefail
: "${YOUTUBE_RTMPS_URL:?Set the stream URL from YouTube Live Control Room}"
: "${YOUTUBE_STREAM_KEY:?Set the stream key privately}"
INPUT=${1:-loop.mp4}
exec ffmpeg -re -stream_loop -1 -i "$INPUT"
-c:v libx264 -preset veryfast -pix_fmt yuv420p
-r 30 -g 60 -keyint_min 60 -sc_threshold 0
-b:v 2500k -maxrate 2500k -bufsize 5000k
-c:a aac -b:a 128k -ar 44100
-f flv "${YOUTUBE_RTMPS_URL%/}/${YOUTUBE_STREAM_KEY}"- Save the file and make it executable:
chmod +x youtube-loop.sh. - Provide the URL and key privately in your shell environment, then run the script with the file path. For example:
YOUTUBE_RTMPS_URL='URL_FROM_LIVE_CONTROL_ROOM' YOUTUBE_STREAM_KEY='YOUR_PRIVATE_KEY' ./youtube-loop.sh /path/to/video.mp4. Replace the quoted values with the exact values from Live Control Room. Avoid putting real credentials in shell history, a shared script, logs, or source control; use a protected environment or secret store appropriate to your setup. - Watch FFmpeg’s output for connection or encoding errors, then check the preview and stream health in Live Control Room.
FFmpeg documents -stream_loop -1 as infinite input looping and -re as reading input at its native rate. See the FFmpeg documentation. This is a template, not a universal tested configuration. Its 30 fps, H.264, and bitrate values are illustrative of a 720p/30-style setup; match the bitrate and resolution to the actual source and a stable upload connection.

Choose encoder settings that fit your video
YouTube’s current encoder guidance recommends H.264 for RTMP/RTMPS, constant bitrate (CBR), a two-second keyframe interval (with a four-second maximum), and AAC or MP3 audio. For stereo audio, it lists 44.1 kHz and 128 Kbps. Consult YouTube’s encoder settings, bitrates, and resolutions and test the setup before relying on it.
| Script setting | What it does | How to adapt it |
|---|---|---|
-r 30 -g 60 -keyint_min 60 -sc_threshold 0 |
Sets 30 fps and a 60-frame GOP, corresponding to a two-second keyframe interval at 30 fps. | For another frame rate, set the GOP length to approximately twice that rate for a two-second interval. Keep the keyframe interval within YouTube’s stated maximum. |
-b:v 2500k -maxrate 2500k -bufsize 5000k |
Sets an illustrative video bitrate and rate-control buffer. | Choose a bitrate supported by the source resolution and sustainable upload bandwidth; the values are not universal YouTube requirements. |
-c:a aac -b:a 128k -ar 44100 |
Encodes audio as AAC at 128 Kbps and 44.1 kHz. | Check that the input contains the audio you expect and that the stream’s audio is audible and in sync during testing. |
-pix_fmt yuv420p |
Produces a broadly compatible pixel format for the encoded video. | Check the output preview and stream health; compatibility and available formats depend on the FFmpeg build and source. |
Test the event and start the live stream
- Use a controlled test event before publishing a long-running or public broadcast. Verify picture, sound, stream health, and that the file repeats as intended. YouTube recommends testing and monitoring; see its live-streaming tips.
- For a scheduled stream, encoder transmission and event activation can be separate steps. Wait for the Live Control Room preview, then use its Go live action unless you have deliberately enabled auto-start. Follow the settings for the specific event.
- When finished, stop FFmpeg deliberately and end the event using Live Control Room controls as appropriate. YouTube says streams under 12 hours are automatically archived; do not assume a single archive for a longer continuous loop. See YouTube’s encoder setup and archive guidance.
Keep the loop running: local Linux or hosted Linux
| Where FFmpeg runs | Availability considerations | Trade-offs |
|---|---|---|
| Your Linux desktop or server | Runs only while the machine, network connection, and FFmpeg process remain available. | No separate hosting service is needed, but the computer must stay on and connected. You manage the operating system, process, and recovery. |
| An always-on hosted Linux instance | Can keep the process away from home, subject to the host’s availability and configuration. | Requires administration and has a hosting cost; no particular provider or price is established here. You remain responsible for FFmpeg and recovery. |
FFmpeg’s formats documentation shows RTMP FIFO output options that can attempt recovery after temporary failures, but adding recovery logic does not guarantee that every interruption will recover. See FFmpeg Formats Documentation. Avoid -re for a live input; FFmpeg cautions that rate limiting a real-time input can cause packet loss. This script uses it for a local file.

RTMPS or HLS?
For this simple shell-script file loop, use RTMPS by default: YouTube recommends it as RTMP over TLS/SSL, and it fits the FFmpeg RTMP output pattern above. YouTube also supports HLS for cases such as HDR or codecs not supported over RTMP, but segmented delivery has higher latency. Choose HLS only when the stream’s codec or other requirements call for it, and follow YouTube’s current ingest guidance rather than substituting an HLS URL into this RTMPS template.
Troubleshooting common failures
- FFmpeg says the encoder is unavailable: Your installed build may not include
libx264. Checkffmpeg -encodersand install a trusted build that includes a compatible H.264 encoder, or adjust the command to an encoder your build provides. - Connection fails immediately: Recheck the exact server URL and stream key for the selected YouTube stream, ensure the URL/key combination is assembled as expected by that endpoint, and confirm outbound network access. Reset an exposed key in Live Control Room and update the environment value.
- The preview connects but the event is not public/live: A scheduled event may still need the preview and Go live action. Check whether auto-start is enabled for that stream.
- Video stutters or YouTube reports poor stream health: Reduce the bitrate or resolution to a level the source and sustained upload connection can support, then test again. Check that the selected frame rate and keyframe interval are coherent.
- Audio is missing, distorted, or out of sync: Confirm the source has the intended audio track, inspect FFmpeg output, and test the stream preview. Ensure the chosen audio codec and sample rate match the intended setup.
- The stream stops after the loop runs for a while: Infinite file looping does not restart a failed FFmpeg process or repair every network interruption. Check the terminal or service logs and network, then restart the process; if you add FIFO recovery options, test their behavior rather than assuming uninterrupted recovery.
- The archived video is shorter than the broadcast: YouTube’s automatic archive statement covers streams under 12 hours only. Plan separate, shorter events or another archive approach for longer continuous broadcasts.
Copyright and channel-policy checks
Only loop video and audio you have permission to broadcast. A file being available online or already uploaded to YouTube does not by itself establish that you may rebroadcast it. Review YouTube’s copyright and live-stream rules before scheduling, and consider how repetitive or reused material fits your channel and intended use. A looping script handles transmission; it does not grant rights or guarantee monetization or policy approval. Check the copyright safety checklist before going live.
