For one file, FFmpeg’s -stream_loop -1 option loops indefinitely; for multiple files, use FFmpeg’s concat demuxer with a correctly formatted list. YouTube’s recommended H.264 ingest ranges are 3–8 Mbps for 720p30 and 5–14 Mbps for 1080p30, but neither range guarantees your Pi or Indian ISP connection will manage that workload reliably.
What you need before starting
- A Raspberry Pi 4 Model B with Raspberry Pi OS installed and enough local storage for your media.
- A 5 V, 3 A (15 W) USB-C power supply, the rating specified by Raspberry Pi’s getting-started documentation.
- FFmpeg installed, with the encoders needed for your chosen command. Check your installed build rather than assuming every Raspberry Pi OS package includes the same options.
- A stable internet connection with sufficient upload capacity. Test from the connection and location you will use; no nationwide Indian upload speed can be assumed.
- Video and audio that you have permission to broadcast. Copyright status and channel eligibility depend on the specific media and account; check your current YouTube Studio status.
A wired Ethernet connection is a practical choice where available, but it does not guarantee stream stability. The official sources cited here do not establish a required SD-card size or measure this exact Pi 4 workflow.

Check FFmpeg and its available encoders
On the Pi, inspect the installed version and encoder list before building the command:
ffmpeg -version
ffmpeg -encodersConfirm that the build offers the video and audio encoders you intend to use. The examples below use libx264 for H.264 video and AAC audio; if either is unavailable, choose a supported encoder and verify that it matches YouTube’s ingest requirements. These commands are setup examples, not a tested performance result for every Pi 4.

Loop one video continuously
For a single file, put -stream_loop -1 before the input it applies to. FFmpeg’s command-line options generally apply to the next input or output, so placement matters. The documented indefinite-loop pattern is -stream_loop -1 -i input.mp4 (FFmpeg documentation).
ffmpeg -re -stream_loop -1 -i input.mp4
-c:v libx264 -preset veryfast -pix_fmt yuv420p
-b:v 3000k -maxrate 3000k -bufsize 6000k
-r 30 -g 60 -keyint_min 60 -sc_threshold 0
-c:a aac -b:a 128k -ar 44100
-f flv "rtmps://YOUR_SERVER_URL/YOUR_STREAM_KEY"Replace the input filename and RTMPS destination with your own values. In this illustrative command, -re reads the file at approximately real-time speed, -r 30 sets 30 frames per second, and -g 60 targets a 60-frame GOP—two seconds at 30 fps. The example bitrate is only a starting point; select a YouTube-recommended range appropriate to your resolution and test it against both the Pi and your actual upload connection. The FFmpeg output URL format depends on the server URL and key YouTube gives your stream.

Build a playlist from multiple files
-stream_loop -1 loops an input; it does not automatically turn every playlist format into an FFmpeg input. For a simple sequence of files, one supported approach is the concat demuxer. Create a text file called playlist.txt with one entry per file, in playback order:
file '/home/pi/videos/part1.mp4'
file '/home/pi/videos/part2.mp4'
file '/home/pi/videos/part3.mp4'Then loop that concat input by placing the loop option before -i:

-c:a aac -b:a 128k -ar 44100
-f flv "rtmps://YOUR_SERVER_URL/YOUR_STREAM_KEY"Use the concat demuxer when the files’ streams are compatible—especially their codecs, time bases, dimensions and audio parameters. It joins streams; it does not automatically normalize different formats or create polished transitions. If files differ, convert them to compatible formats first or use a filter-based approach designed for those inputs. Paths in the list must be valid from the directory where FFmpeg runs. The -safe 0 option permits absolute paths in this local list, so only use a playlist file you control.
Choose YouTube ingest settings
YouTube’s current encoder guidance recommends H.264 bitrate ranges for these two common 30 fps choices; they are platform recommendations, not proof that a Pi or a particular Indian connection can sustain them (YouTube encoder settings).

| Output target | YouTube H.264 recommendation | Practical decision |
|---|---|---|
| 720p30 | 3–8 Mbps | Try the lower end if upload capacity is uncertain; confirm stream health and Pi stability before increasing. |
| 1080p30 | 5–14 Mbps | Use only if the source quality, Pi encoding path and measured upload connection support it reliably. |
- Rate control: YouTube recommends constant bitrate (CBR).
- Keyframes: YouTube recommends a keyframe every two seconds and no interval longer than four seconds. At 30 fps, a 60-frame GOP corresponds to two seconds.
- Audio: YouTube supports AAC or MP3 audio for RTMP/RTMPS ingest; the example uses AAC.
- Secure ingest: YouTube recommends RTMPS, an encrypted extension of RTMP. Use the server URL supplied for the live stream.
Start with representative footage and audio. YouTube advises testing before going live; watch Live Control Room’s preview and stream-health messages, and reduce bitrate or processing demands if the stream is unstable. A chosen resolution is not guaranteed to work on every Raspberry Pi 4 configuration, and no Pi performance benchmark is established here.
Connect FFmpeg to YouTube Live
- Open YouTube’s encoder setup guidance and follow the current YouTube Studio workflow to create or select a live stream.
- Copy the stream server URL and stream key provided by YouTube into the FFmpeg output destination. Treat the key as a password: anyone who obtains it may be able to send video to that stream.
- Run the appropriate single-file or concat command on the Pi. Check FFmpeg’s output for connection errors, encoder failures and ongoing frame progress.
- In YouTube Studio’s Live Control Room, confirm that the incoming preview appears and review stream health. Start or confirm the broadcast there as the selected workflow requires.
- For a new channel’s first live stream, allow for activation to take up to 24 hours; that is a possible wait, not a guaranteed activation time.
Troubleshoot common failures
| Symptom | Likely cause | What to check |
|---|---|---|
| YouTube shows no incoming video | Wrong server URL or key, stream not activated, or FFmpeg failed to connect. | Re-copy the current URL and key from Studio, check FFmpeg’s error output, and verify live streaming is enabled for the channel. |
| Stream health warns of insufficient bitrate or connection issues | The upload link cannot sustain the selected bitrate, or its throughput varies. | Run a representative test on the same connection, lower the bitrate within the recommendation range, and reassess stream health. |
| FFmpeg reports an encoder not found | The installed build lacks the encoder named in the command. | Inspect ffmpeg -encoders and use an available encoder compatible with YouTube’s accepted settings. |
| Playlist stops, skips, or fails at a file boundary | Invalid list path or incompatible streams among concat inputs. | Check each path and file order; normalize differing codecs, dimensions, frame rates or audio parameters before using the concat demuxer. |
| Video stutters or the Pi becomes unstable | The selected encode workload may exceed what this Pi configuration can sustain, or system resources may be constrained. | Test at a lower output resolution or bitrate and inspect the Pi during a representative run. No specific maximum Pi 4 resolution or thermal result is established for this workflow. |
Or let it run in the cloud
If you want a YouTube loop without keeping the Pi or another computer running, StreamNeo is a cloud service for uploaded videos and playlists. Upload your recording, add your YouTube stream key, and go live. Nothing has to stay on at home; each slot streams uploaded quality up to 4K 60fps at one flat price, with automatic recovery if YouTube drops the stream. The first day is free with no card. Monthly billing is $9.99 per month. StreamNeo streams to YouTube only and plays uploaded videos rather than broadcasting a camera feed. Start your free StreamNeo day.
