To stream an authorized Bengali devotional video on repeat as a YouTube Live broadcast, create a stream in YouTube Live Control Room, then use FFmpeg to send the file to YouTube’s ingest server with a private stream key. The example below loops one file continuously; YouTube recommends RTMPS, H.264, constant bitrate (CBR), and a two-second keyframe interval for encoder streams.
Before you start: confirm eligibility and permissions
- Your channel must have live streaming enabled and be verified, with no live-stream restriction in the preceding 90 days. YouTube’s current guidance sets the minimum age to live stream at 16. Check the requirements in YouTube’s live-streaming eligibility guidance.
- Secure the necessary rights to broadcast the video, music or performance, and artwork. A devotional subject, public availability, attribution, or using a live encoder does not by itself establish permission.
- Check YouTube’s current rules for your content and intended use, including its treatment of repetitive prerecorded livestreams and monetization. Do not assume that looping a recording qualifies it for monetization.
- Have FFmpeg installed on a computer that can remain powered on and connected to the internet for the broadcast. This method uses that computer to read and send the file continuously.
Create the YouTube stream and protect its key
- Open YouTube Live Control Room and create or schedule a stream. Follow YouTube’s encoder setup instructions.
- Copy the server URL and stream key shown for the stream. You will combine them in FFmpeg as an ingest address. Use the exact values YouTube supplies; the example below uses placeholders.
- Treat the stream key like a password. Do not publish it, include a real key in screenshots or public scripts, or leave it in shell history where others can access it. If it is exposed, replace or reset it in YouTube Studio before broadcasting again.
Loop a single video with FFmpeg
In a terminal, run the following schematic command after replacing input.mp4 with your file and the placeholder ingest address with the server URL and key provided by YouTube:
ffmpeg -re -stream_loop -1 -i input.mp4
-c:v libx264 -pix_fmt yuv420p -r 30 -g 60 -b:v 4M
-c:a aac -b:a 128k
-f flv "rtmps://SERVER/STREAM_KEY"This is an adaptable example, not a tested universal command. FFmpeg documents -stream_loop -1 for infinite looping and -re for reading an input at its native frame rate so it is sent in real time. In this example, the output uses H.264 video, AAC audio, 30 frames per second, and a GOP size of 60 frames—two seconds at 30 fps. The 4 Mbps video bitrate is an example, not a promise of a particular picture quality. Confirm the current YouTube ingest address, the appropriate resolution and bitrate, and the options supported by your installed FFmpeg build. See the FFmpeg command-line documentation and YouTube’s encoder settings guidance.
Use YouTube’s recommended encoder settings
- Protocol: YouTube recommends RTMPS for Live. RTMPS tunnels RTMP through an SSL connection, as described in Google’s RTMPS ingestion guide.
- Video: Use H.264 for RTMP/RTMPS encoding and constant bitrate (CBR). Choose a bitrate and resolution that your connection can sustain reliably; bitrate alone does not guarantee a particular quality.
- Keyframes: Set a two-second keyframe interval; YouTube says not to exceed four seconds. For 30 fps,
-g 60requests a 60-frame GOP. - Audio: The sample uses AAC at 128 kbps. Check YouTube’s current settings guidance against your source and chosen output.
- Example bitrate reference: YouTube’s current table lists 2–6 Mbps for 720p at 30 fps. This is guidance for that resolution and frame rate, not a bitrate requirement for every stream.
What to expect when the file reaches its end
With -stream_loop -1, FFmpeg repeats the input instead of ending when it reaches the last frame. The loop has no built-in transition, so the end-to-start change may be noticeable in the picture or audio. Check the file’s final seconds and opening seconds before going live. If you are using a playlist or multiple files, this single-file command is not sufficient; prepare and test an input workflow that handles your particular playlist rather than assuming the example will switch files.

Test the stream and monitor its health
- Before going live to your intended audience, test with representative motion and audio from the video. YouTube recommends a speed test and checking the stream with content similar to what you will broadcast.
- Start FFmpeg and check Live Control Room for the incoming preview, stream health, and any messages. Resolve warnings before relying on the broadcast.
- Confirm that both picture and sound are present and that the stream is stable. A connection that cannot sustain the selected output can cause health warnings or interruptions.
- To stop, interrupt FFmpeg (for example, with
Ctrl+Cin the terminal running it), then confirm the stream has ended in Live Control Room. YouTube’s encoder instructions describe stopping the encoder to end the stream.
YouTube says streams under 12 hours are automatically archived. That is an archiving note, not a guarantee that a broadcast can run indefinitely or that an uninterrupted archive will be created for a longer stream. For current details, see YouTube’s encoder setup page.
Troubleshoot common problems
| Symptom | Likely cause | What to check |
|---|---|---|
| YouTube does not receive a stream | The server URL or key is incorrect, the key is for another stream, or FFmpeg cannot connect. | Copy the current server URL and key from the correct Live Control Room stream; check FFmpeg’s terminal output and the network connection. Keep the key private. |
| Video appears but audio is missing | The source has no usable audio track, or the audio stream is not being encoded as expected. | Check the input file’s audio in a local player and inspect FFmpeg’s output for audio-stream errors. The example encodes audio as AAC. |
| Live Control Room reports poor stream health | The connection may not sustain the output, or the encoder settings may not match YouTube’s guidance. | Monitor Live Control Room messages, run a speed test, and select a reliable output quality. Check CBR, H.264, and the keyframe interval against YouTube’s current settings. |
| The video or sound jumps at the loop point | The end of the source does not join smoothly to its beginning. | Review the final and opening moments of the file. Edit or choose material with a more suitable transition, then test the loop again. |
| The stream stops when the computer or connection stops | FFmpeg is sending from the local computer, so it depends on that computer and its internet connection remaining available. | Keep the computer powered and connected while using this method; monitor the encoder and stream health. |
Or let it run in the cloud
If you do not want a computer at home to stay on, StreamNeo runs an uploaded video as a continuous YouTube stream from the cloud. Upload your recording or build a playlist, add your YouTube stream key once, and go live. Nothing has to stay running at home; it streams the uploaded file as made, up to 4K 60fps at one price per slot, and can automatically recover if YouTube drops the stream. The first day is free with no card. Monthly pricing is $9.99 per month. Start your free day with StreamNeo.
