You can stream from a Raspberry Pi running Raspberry Pi OS Lite by installing FFmpeg, choosing the right input for your camera or video source, and sending the output to YouTube Live over RTMPS. The key is to match the FFmpeg command to the source, then test the Pi’s encoding capacity and your upload connection before going public. YouTube recommends H.264, constant bitrate (CBR), and a two-second keyframe interval.
What you need before you start
- A Raspberry Pi with Raspberry Pi OS Lite installed and access to its command line, usually through SSH or a local console. Lite is the command-line-only version intended for headless setups. Raspberry Pi’s headless setup guidance recommends Lite for headless systems.
- A working video source: a Raspberry Pi camera, USB camera, network stream, or prerecorded file. These use different FFmpeg inputs, so there is no single capture command for all of them.
- A YouTube channel with live streaming available, plus the current ingest destination and stream key from YouTube Live Control Room.
- A stable upload connection at the location where the Pi will run. India-specific ISP performance figures are not established here; test the connection at the actual site and at the time you expect to stream.
Raspberry Pi OS Lite includes rpicam-apps-lite, including rpicam-vid for Raspberry Pi camera capture. Check the installed app’s options with rpicam-vid --help, since available options vary with software and camera hardware. Raspberry Pi camera software documentation explains the camera applications and their encoding behavior.

ffmpeg -version ffmpeg -encoders
Package versions and codec support depend on the Raspberry Pi OS release and repository. Do not assume a particular hardware encoder is available just because the Pi has a camera; inspect your local FFmpeg encoder list and test the selected path.
Choose a YouTube stream profile
YouTube recommends RTMPS, H.264 video, constant bitrate, and a keyframe interval of two seconds (not over four seconds). Its recommended H.264 bitrates include the following. These are YouTube recommendations, not guarantees about what a particular Pi or connection can sustain. Google / YouTube Help: Choose live encoder settings, bitrates, and resolutions (accessed 2026).

Start with a profile your Pi can encode and your measured, stable upload can carry. Leave headroom for network variation rather than selecting a bitrate at the edge of a speed test. YouTube recommends testing upload bitrate and choosing stream quality based on the connection; watch the Live Control Room’s stream-health messages during testing and the event.
Get the YouTube destination and protect the stream key
- Open YouTube Live Control Room and create or select the live stream.
- Copy the current ingest URL and protocol shown for that stream. YouTube recommends RTMPS, described as “a secure extension to the popular RTMP streaming video protocol.”
- Copy the stream key and treat it like a password. Do not include it in public scripts, screenshots, repositories, or shared logs. Use a placeholder such as
<STREAM_KEY>in examples, and avoid saving a real key in shell history.
Stream-key labels, ingest endpoints, account eligibility, and live settings can vary or change. Use the values displayed in your own Live Control Room rather than relying on a copied endpoint.

Build the FFmpeg command for your input
The examples below illustrate the command shape, not universal settings. Replace placeholders with the values shown by your source and YouTube. Use the YouTube RTMPS destination, including its stream-key path, as displayed in Live Control Room.
Prerecorded file
For a file, -re reads input at its native rate instead of sending it as fast as possible. This example re-encodes to H.264 and AAC; set frame size, frame rate, and bitrate to the profile you selected and can sustain:

Confirm the output resolution and audio format suit the selected stream.
Raspberry Pi camera
Raspberry Pi documents rpicam-vid as the camera capture tool; it writes an encoded bitstream and uses hardware H.264 encoding when available. Its FFmpeg/libav backend can encode audio and video and uses hardware H.264 when present. Exact options depend on installed versions and camera hardware, so first inspect rpicam-vid --help and the relevant Raspberry Pi camera documentation. Do not paste a file-input command over a live camera capture pipeline without adapting the input and timing.

Raspberry Pi 5 uses software video encoders. Raspberry Pi documentation says --low-latency reduces encoding latency, with slightly worse coding efficiency, potentially less efficient multicore use, and possibly slightly lower maximum frame rate; it notes 1080p30 remains readily achievable in its documented context. This is not a performance guarantee for every FFmpeg pipeline or for other Pi models. Test your actual capture and stream workload.
USB camera or network stream
A USB camera or RTSP/network feed needs the input syntax appropriate to its device and protocol. Inspect available devices and the source’s own documentation, then substitute that input for -i /path/to/video.mp4. Live capture inputs generally arrive in real time already, unlike a prerecorded file; adding -re indiscriminately can cause pacing problems. Network feeds also depend on the upstream source staying reachable.
When stream copy may work
-c:v copy avoids video encoding, but is only suitable when the source is already encoded in a format and settings YouTube accepts and its timestamps and container path work. If the source needs a different resolution, frame rate, bitrate, or codec, re-encode it. Whether encoding is practical depends on the Pi model and the encoders actually available in your FFmpeg build.
Run a private test and verify the whole path
- Set the YouTube stream to private or unlisted for testing, where available in your account, then start FFmpeg with the real ingest destination and protected key.
- Use movement and audio similar to the intended stream. A static test image does not reveal the same encoding load as moving footage.
- Watch Live Control Room for stream-health messages and confirm that video and audio arrive as expected.
- On the Pi, monitor CPU use, dropped frames, temperature and throttling behavior, and whether the network remains stable. If any part falters, reduce resolution, frame rate, or bitrate and test again.
- Repeat from the actual installation location and at the time of day the stream will run. Wi-Fi, mobile uplink conditions, congestion, router placement, and service plans can all affect sustained upload.
Troubleshooting common failures
| Symptom | Likely cause | What to check |
|---|---|---|
| YouTube receives no video | Wrong ingest URL or key, unavailable live streaming, or malformed output destination | Copy the current destination and key from Live Control Room; verify the account’s live status and FFmpeg output for connection errors. |
| Video connects but stream health is poor | Bitrate exceeds stable upload capacity, or the connection is fluctuating | Test upload at the site; reduce bitrate or resolution and check stream-health feedback. |
| Frames drop or the Pi struggles | Encoding load exceeds the model’s real-time capacity | Inspect available encoders, CPU load, temperature and throttling. Try a lower frame rate or resolution, or a valid stream-copy path if the input already matches YouTube requirements. |
| Audio is missing or out of sync | Audio was not captured or mapped, unsupported input format, or timestamps differ | Confirm the selected input contains audio, check FFmpeg’s input stream listing and logs, and use AAC output when re-encoding for a standard stereo stream. |
| Camera command fails | Camera not detected, incompatible camera/software combination, or command options differ | Check camera connection and detection, then consult rpicam-vid --help and Raspberry Pi’s camera documentation for the installed version. |
| Stream stops after starting | Network interruption, source failure, or encoder process exit | Inspect FFmpeg’s final log lines and source availability; restore the connection or source and restart the process. A local FFmpeg setup does not automatically provide cloud-based recovery. |
