To stream from a Raspberry Pi to YouTube with FFmpeg, copy the ingest URL and stream key from YouTube Studio’s Live Control Room, then give FFmpeg a compatible video and audio input and send its output to that exact endpoint. Use RTMPS if your FFmpeg build supports it, test before going live, and keep the stream key secret. The command depends on your Pi model and input, so the example below is a template—not a guaranteed, tested command for every setup.
Before you begin
You need a YouTube channel with access to the Live Control Room, FFmpeg installed on the Pi, a video source FFmpeg can read, and an internet connection with enough upload capacity for your stream. Audio is optional if your source has none; do not add an audio stream unless your setup needs one.
First identify your source. It might be a camera, a capture device, or an already encoded file or feed. The FFmpeg input options and the Pi’s ability to encode in real time depend on that source and the Pi model. Raspberry Pi’s camera documentation describes rpicam-vid capture and streaming, including use of FFmpeg/libav and hardware H.264 encoding where available.
Get the YouTube stream URL and key
- In YouTube Studio, select Create > Go Live to open the Live Control Room.
- Open the Stream tab, then create or select the stream.
- Copy the stream URL and stream key shown there. Use those exact values in FFmpeg; do not guess the host or key format. YouTube describes stream keys as “like your YouTube stream’s password and address” in its live stream settings guidance.
The URL identifies YouTube’s ingest endpoint; the key identifies and authenticates your stream. Treat the key like a password: do not share it in screenshots, paste it into a public forum, commit it to a repository, or leave it exposed in shell history or a script that others can read.

Choose RTMPS and prepare FFmpeg output
YouTube supports RTMP and RTMPS encoder ingestion and recommends RTMPS because it encrypts the connection. Copy the RTMPS URL from the Live Control Room rather than changing an RTMP URL by guesswork. Your FFmpeg build must support the TLS connection required by that endpoint. See YouTube’s RTMPS guidance and FFmpeg’s RTMP protocol documentation for protocol and URL details.
FFmpeg’s command has three jobs: read your actual input, map the video and any intended audio, then encode or copy those streams into a format YouTube accepts and send them to the supplied endpoint. The following is only a structural example. Replace every placeholder with values for your source and Live Control Room; angle-bracket values are not literal shell arguments.

-c:v <VIDEO_CODEC_OR_copy> -b:v <VIDEO_BITRATE>
-c:a <AUDIO_CODEC_OR_copy>
-f flv "<YOUTUBE_INGEST_URL>/<STREAM_KEY>"The example assumes the copied URL and key are combined in the form expected by the endpoint. Follow the URL format displayed in the Live Control Room and FFmpeg’s protocol documentation; do not add or remove path components unless YouTube’s supplied URL requires it. The -map options select the first video stream and optional first audio stream when present. Change them if your input uses different stream indexes. Remove audio mapping and encoding options if there is no audio, or map the intended audio explicitly.
If the input is already encoded
If the source is already H.264 and its pixel format, timestamps, frame rate, and bitrate are acceptable, -c:v copy can avoid another video encode and reduce work for the Pi. Copying does not make an incompatible source compatible; check the stream’s properties and YouTube’s requirements first. Audio may still need AAC encoding even when video is copied.

If FFmpeg must encode the video
Encoding gives you control over output settings but uses the Pi’s processing capacity. YouTube’s encoder guidance lists H.264, H.265, or AV1 video; AAC or MP3 audio; constant bitrate (CBR); and frame rates up to 60 fps. It recommends a two-second keyframe interval and says not to exceed four seconds. For H.264 at 720p30, YouTube’s guidance lists 3–8 Mbps; this is a platform recommendation, not a guarantee of image quality or proof that a particular Pi can encode at that rate. Check the current YouTube encoder settings before choosing values.
For an H.264 encode, FFmpeg options commonly include an encoder selection, bitrate and maximum rate, buffer size, and a keyframe interval. The exact options depend on the encoder in your FFmpeg build. For example, an interval equivalent to two seconds depends on frame rate: at 30 fps that means a 60-frame interval. Do not copy a hardware-encoder option from another Pi model without confirming that your hardware and FFmpeg build provide it.

YouTube detects resolution and frame rate automatically by default; manual resolution settings use a custom stream key. YouTube transcodes incoming streams for playback formats. Select a resolution and frame rate your source, Pi, and upload connection can sustain, then verify the result in the Live Control Room’s stream health rather than assuming a particular bitrate will look good on every network.
Account for Raspberry Pi model and capture source
Raspberry Pi generations do not have identical encoding hardware. Raspberry Pi documents that Pi 5 uses software video encoders; its rpicam-vid --low-latency option can reduce latency, with trade-offs in coding efficiency and potentially maximum frame rate. Do not assume hardware H.264 encoder flags for an earlier model apply to Pi 5, or that a target frame rate is achievable on every Pi. Consult the Raspberry Pi camera software documentation for the relevant capture and streaming approach.

If you are using a camera, first establish how it appears to FFmpeg and whether the camera software is already producing an encoded stream. If you are capturing a game console or another video source, the capture device and its drivers determine how FFmpeg receives video and audio. Those details change the input options; there is no single correct capture command for every Raspberry Pi setup.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Start, preview, and go live
- Run the completed FFmpeg command from the Pi. Watch its output for input, codec, connection, and muxer errors.
- In the Live Control Room, wait for YouTube to receive the feed and show a preview. Check that the expected video and audio appear and review stream health.
- For a scheduled stream, select Go live in YouTube when the preview and stream state are ready. Starting FFmpeg sends the feed, but does not itself complete YouTube’s go-live workflow.
- To finish, stop FFmpeg and end the stream through YouTube’s workflow in the Live Control Room.
Before an event, test with representative motion and audio. YouTube recommends upload bandwidth with 20% headroom over the total stream bitrate in its streaming tips. Measure the connection you will actually use and include audio and any other stream data in your total.
Stream-key and connection troubleshooting
No preview or connection failure
- Compare the URL and key in the command with the values currently displayed in the Live Control Room. Check FFmpeg’s log for DNS, authentication, TLS, or muxer errors.
- If you reset the key, replace the old key wherever the encoder uses it.
- Confirm that the output uses an appropriate FLV muxer and that the supplied endpoint’s URL format is intact.
RTMPS certificate, TLS, or timeout error
- Confirm that you copied an RTMPS endpoint (the URL begins with
rtmps) and that your FFmpeg build supports the required TLS protocol. - Follow YouTube’s RTMPS troubleshooting guidance. For some SSL errors it suggests specifying port 443 with the supplied URL; do not substitute a different host or port without that guidance.
Dropped frames or unstable output
- Compare the total stream bitrate with measured upload capacity and preserve the recommended headroom. Lower the bitrate or resolution if the connection cannot sustain the chosen output.
- If the Pi is encoding, reduce the workload or choose settings it can sustain. Test with movement similar to the actual content and watch YouTube’s stream-health status.
Video or audio is missing or wrong
- Check that the output codecs are supported and that the
-mapoptions point to the intended input streams. - Inspect whether the source actually supplies audio. Do not assume an audio stream exists or add silent audio just to satisfy a template.
Key exposed or possibly compromised
Reset the key in the Live Control Room and update the encoder. YouTube says only channel owners or managers can reset a stream key; see its stream settings instructions.
Keep the channel live without keeping the Pi on
For a live feed from a camera or capture device, FFmpeg on a Raspberry Pi is the hands-on route: the Pi reads and sends the live source. If your goal instead is to keep a YouTube channel live by looping uploaded recordings, StreamNeo is a cloud alternative—not a camera encoder. Upload a recording or build a playlist, add your YouTube stream key once, and go live. StreamNeo loops the uploaded video from the cloud, so your computer and home connection do not have to stay on. Each slot streams the uploaded quality up to 4K 60fps at one flat price per slot, includes automatic recovery if YouTube drops the stream, and has a first day free with no card. Monthly is $9.99 per month. UPI and cards are available in India; card checkout is available worldwide. Learn more at StreamNeo, or start the free first day.

YouTube copyright and reused-content checks
Using your own stream key does not grant rights to the video or audio you send. Before streaming, make sure you have the necessary rights or permissions for gameplay footage, music, commentary, and other material in the feed. YouTube’s copyright and monetization decisions are separate from whether FFmpeg connects successfully; check YouTube’s current policies for your channel and content before relying on a stream for monetization. A technically valid live stream is not, by itself, evidence that content meets YouTube’s reused-content or monetization requirements.
