You can stream a local video playlist from a Raspberry Pi 5 to YouTube Live with FFmpeg. If the files have compatible streams and already meet YouTube’s ingest requirements, use the concat demuxer and -c copy to avoid re-encoding. If they do not, you will need to preprocess or encode them—and Pi 5 uses software video encoders, so test the workload before relying on it for a long broadcast.
Before you start
- A Raspberry Pi 5 with Raspberry Pi OS or another Linux installation, enough storage for the media, and a stable internet connection with upload capacity for the stream.
- FFmpeg installed with the required input, output muxer, and codecs. Check the installed build and its option behavior; FFmpeg versions and build configurations can differ.
- A YouTube channel that can use live streaming, with a stream created or selected in YouTube Studio.
- A curated playlist and a private place to store the YouTube stream key.
YouTube recommends RTMPS for encrypted ingest. Copy the RTMPS stream URL from Live Control Room rather than assuming an ordinary RTMP URL is encrypted. YouTube’s live encoder settings describe its current conventional RTMP/RTMPS recommendations; confirm the applicable table there before choosing output settings.
Inspect and prepare the video folder
Check the actual streams, not just the file extensions
MP4 is a container, not a guarantee that two files contain the same codecs, stream layout, or timing. Inspect representative files—and ideally every file in the playlist—with ffprobe. Check video and audio codecs, dimensions, frame rate, pixel format, stream count, and duration. Compare the streams and time bases across files before choosing the no-re-encode path.
ffprobe -hide_banner -i "/media/videos/01-intro.mp4"The concat demuxer expects matching streams, including codecs and time bases. Differences may stop concatenation from working correctly. Duration metadata errors can also cause artifacts or gaps. FFmpeg’s concat guidance explains the compatibility constraints and the alternative concat-filter approach.

Make the order explicit
Do not rely on shell glob order if the sequence matters. Create a UTF-8 text file, for example /media/videos/playlist.ffconcat, with the entries in the intended order:
ffconcat version 1.0
file '/media/videos/01-intro.mp4'
file '/media/videos/02-main.mp4'
file '/media/videos/03-outro.mp4'Use the real paths to your files. Paths containing apostrophes, unusual characters, or leading or trailing spaces require careful quoting and escaping; validate the list rather than generating it with a command that assumes every filename is simple.
Choose between stream copy and encoding
| Path | Use it when | What it does and the tradeoff |
|---|---|---|
| Concat demuxer with stream copy | The clips have matching stream layouts, codecs, and time bases, and their encoded streams are already suitable for YouTube ingest. | -c copy avoids re-encoding, but does not change codecs, resolution, frame rate, or bitrate. It cannot make incompatible files compatible or make unsuitable streams meet YouTube’s requirements. Incorrect duration metadata may cause gaps or artifacts. |
| Preprocess or concatenate with the concat filter, then encode | The clips differ or you need to normalize the output format, resolution, frame rate, or bitrate. | Encoding gives you more control over output consistency but adds processing work. Raspberry Pi 5 uses software video encoders, so measure whether it can sustain your actual settings before scheduling a long stream. |
FFmpeg documents copy as avoiding re-encoding and recommends the concat filter for concat operations that require re-encoding. See its concat FAQ. Do not choose stream copy simply because every filename ends in .mp4.

Set YouTube’s ingest settings
For conventional SDR RTMP/RTMPS ingest, YouTube’s current recommendations include H.264 video, constant bitrate (CBR), a keyframe interval of two seconds (not more than four), AAC or MP3 audio, and a maximum frame rate of 60 fps. It recommends progressive scan, square pixels, Rec. 709 SDR color, and stereo audio at 44.1 kHz and 128 kbps. The recommended video bitrate depends on the ingest codec, resolution, and frame rate; use the row for your exact combination in YouTube’s live encoder settings table, not a universal bitrate.
For example, the table available in 2026 lists 10 Mbps for H.264 1080p30 and 12 Mbps for H.264 1080p60. These are recommendations for those specific codec, resolution, and frame-rate combinations, not general targets for every stream. Check the current table when configuring the encoder.
These settings matter most when you are encoding or checking whether existing files are suitable. A stream-copy command passes the encoded streams through; it does not convert them to H.264, make their bitrate constant, or set a new keyframe interval.

Build and run the FFmpeg command
Compatible files: illustrative stream-copy starting point
After confirming the playlist is compatible and the files meet the ingest requirements, the command shape is:
ffmpeg -re -f concat -safe 0 -i /path/to/playlist.ffconcat
-stream_loop -1 -c copy -f flv
'rtmps://INGEST_HOST/APP/STREAM_KEY'Replace the playlist path and endpoint with your own. The URL shown is a placeholder, not a working YouTube endpoint. Copy the RTMPS URL and stream key from YouTube Live Control Room, and check that your FFmpeg build supports the required muxer and codecs. Confirm the placement of -stream_loop against your installed FFmpeg version: it is an input option, and input options apply to the input that follows them. FFmpeg documents the option in its advanced options.
Recommended Free Tools
This is a starting point, not a universal drop-in command. The concat demuxer’s compatibility requirements still apply, and the selected YouTube endpoint and FFmpeg build must accept the output format. If the source streams do not meet YouTube’s ingest requirements, use a tested encoding configuration instead of assuming stream copy will fix them.

When the files need normalization
Use a preprocessing or concat-filter-and-encode workflow when streams differ or need normalization. Choose the output codec, dimensions, frame rate, bitrate, keyframe interval, and audio settings to match the applicable YouTube recommendation. Because Pi 5’s video encoding is software-based, no fixed resolution or frame rate can be promised for every media file and FFmpeg build. Test a representative clip with the filters and settings you intend to use, then check whether processing keeps up with playback. If it does not, preprocess the files on another machine or use a cloud streaming option.
Keep the stream key private
A YouTube stream key tells YouTube to accept an encoder feed and functions like a password. Do not expose it in screenshots, shared logs, scripts given to others, or public repositories. Avoid leaving it in shell history where other users can read it; if it is exposed, reset it in YouTube Studio. See YouTube’s guidance on stream keys.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Preview the feed and go live
- In YouTube Studio, open Live Control Room and create or select the stream you want to use.
- Copy the stream URL and stream key shown there into your FFmpeg output configuration. Prefer the RTMPS URL when supported.
- Start FFmpeg and wait for the incoming feed to appear in Live Control Room’s preview.
- Check the preview, audio and video quality, and the encoder’s output and upload connection. For a scheduled stream, select Go live in Live Control Room when the preview is ready.
- To finish, stop FFmpeg and end the broadcast in Live Control Room as appropriate. YouTube says streams under 12 hours are automatically archived; see its live streaming tips.
YouTube also advises checking that the event is accessible and monitoring audio and video quality throughout the stream. A successful connection at startup does not establish that the feed will remain healthy for the whole broadcast.

What to expect from Raspberry Pi 5
Raspberry Pi’s official camera documentation states: “Raspberry Pi 5 uses software video encoders.” See Raspberry Pi camera software documentation. Stream copy can avoid a video encode when the source streams are already suitable, which makes it the more practical first option for compatible files.
For transcoding, performance depends on the codec, resolution, frame rate, filters, FFmpeg build, thermal conditions, and other system load. No fixed live-transcode capability for this exact workflow is established. Run a representative test and monitor whether the Pi keeps up with playback before depending on it for an extended stream.
Troubleshooting
- Concat reports mismatched streams or the join fails: Compare codecs, stream layouts, and time bases across the files. The concat demuxer needs matching streams; preprocess the clips or use a concat-filter-and-encode workflow if they differ.
- There are gaps, jumps, or artifacts at clip boundaries: Check duration metadata and timestamps as well as stream compatibility. Incorrect duration information can affect concatenation; test the playlist before going live.
- YouTube rejects the feed or does not show a preview: Verify the RTMPS URL and stream key from Live Control Room, confirm that the key is current, and check that the installed FFmpeg build supports the chosen muxer and codecs. Stream copy does not convert a codec or adjust an unsuitable source to YouTube’s settings.
- The Pi cannot keep up after you enable encoding: Test the real codec, resolution, frame rate, filters, and system load. Reduce the encoding workload or preprocess the files elsewhere if the Pi cannot sustain playback speed.
- The stream stops after a key appears in a screenshot or log: Reset the compromised key in YouTube Studio and update FFmpeg with the new one. Treat the key as a password.
- FFmpeg rejects the loop option or loops unexpectedly: Check your installed FFmpeg version’s option documentation and position
-stream_loopas an input option for the playlist input.
