To send a Raspberry Pi video feed to YouTube Live at 720p, configure FFmpeg for H.264, constant bitrate (CBR), and a two-second keyframe interval; use an RTMPS ingest address and stream key from YouTube Live Control Room. Choose 30 or 60 fps according to your camera and Pi, and keep the bitrate within both YouTube’s live guidance and your connection’s reliable upload capacity. The exact FFmpeg input options depend on your capture device, operating system, and installed FFmpeg build, so there is no single verified command that works on every Pi setup.
Before you configure FFmpeg
First identify three things: which Raspberry Pi you have, how video enters it, and where audio comes from. A Pi camera, USB webcam, and capture card can require different FFmpeg input arguments; microphone and camera audio options also vary. Check those details before adapting an encoding template.
- Pi model: Raspberry Pi’s encoding guidance describes hardware H.264 encoding through
h264_v4l2m2mon Pi 4, and software H.264 encoding throughlibx264on Pi 5. Do not assume the Pi 4 encoder is available on a Pi 5, or that either encoder is enabled in your FFmpeg build. - Video input: Determine whether the source is a Raspberry Pi camera, USB camera, or another capture device, and note its supported resolution and frame rates.
- Audio input: Decide whether audio comes from the camera, a separate microphone, or is intentionally absent. The device name and input syntax are system-specific.
- Software support: Check the installed FFmpeg build for the encoder you intend to use. Encoder availability and camera integration depend on the OS, FFmpeg build, and capture setup.
Raspberry Pi’s camera software documentation describes an FFmpeg/libav backend, but that does not make every camera capture path interchangeable with every FFmpeg command. Treat the examples below as encoding and output templates: supply the input arguments that match your actual devices, and confirm that your build supports the selected encoder.
Choose 720p frame rate and bitrate
YouTube’s live encoder guidance, accessed in 2026, lists the following H.264 live-ingest bitrate range for both 720p30 and 720p60. These are live-stream figures, not YouTube’s separate video-upload recommendations.

| Live format | YouTube H.264 live bitrate | When it makes sense |
|---|---|---|
| 1280 × 720 at 30 fps | 3 Mbps minimum; 8 Mbps recommended | Use when the camera produces 30 fps or the Pi and upload connection have limited headroom. |
| 1280 × 720 at 60 fps | 3 Mbps minimum; 8 Mbps recommended | Use only when the source provides 60 fps and the Pi can encode it reliably; motion can look smoother, but the extra frames raise encoding workload. |
The 3–8 Mbps figures are YouTube’s listed H.264 live-ingest values; they are not a guarantee that a particular Pi or network will sustain a stream. Leave capacity for audio and network variation, and use a bitrate your upstream connection can maintain consistently. If the stream drops frames or YouTube reports unstable health, lower the video bitrate or choose 30 fps rather than forcing a higher setting.
Set the live encoder parameters
For a straightforward 720p Pi stream, H.264 is a compatibility-focused choice. YouTube accepts other video codecs too, so H.264 is not an exclusive YouTube requirement. For typical SDR, YouTube’s advanced recommendations include square pixels, progressive scan, Rec. 709, AAC or MP3 audio, and 128 Kbps stereo audio.
- Resolution: 1280 × 720.
- Frame rate: 30 or 60 frames per second, matched to the source and what the Pi can sustain.
- Video codec: H.264.
- Rate control: CBR (constant bitrate).
- Keyframes: one every two seconds. YouTube recommends two seconds and lists four seconds as the maximum interval.
- Protocol: RTMPS is YouTube’s recommended ingest protocol; use the server address provided in Live Control Room.
- Audio: if sending stereo audio, AAC or MP3 at 128 Kbps is among YouTube’s advanced recommendations.
A two-second keyframe interval means the GOP size should correspond to twice the frame rate: 60 frames at 30 fps or 120 frames at 60 fps. In FFmpeg terms, -g commonly sets the GOP size in frames, but encoder options differ. Confirm how your selected encoder interprets keyframe settings rather than assuming the same flag behaves identically across builds.

This example uses 30 fps and a 5 Mbps target as an illustrative value within YouTube’s listed 720p H.264 live range, not a recommended setting for every connection. It disables audio with -an; remove that option and add the correct audio input and encoder settings if your stream needs sound. Check that your hardware encoder accepts the rate-control options shown and provides the CBR behavior you intend.
Pi 5: software H.264, with CPU headroom
Raspberry Pi’s current performance guidance describes software encoding with libx264 on Pi 5. Software encoding uses CPU capacity, so monitor load and stream stability during a representative test. Raspberry Pi’s camera documentation notes that Pi 5 software encoding can have greater latency than older hardware encoders in some real-time cases; for the rpicam-vid camera workflow, --low-latency reduces encoding latency with a coding-efficiency tradeoff.

As with the Pi 4 template, replace the explanatory input placeholders, verify the options supported by your FFmpeg build, and configure audio separately if needed. The example’s preset and CBR-related options are not a guarantee that every build or output path will behave identically; confirm encoder behavior and YouTube stream health in a test.
Adjusting the templates for 60 fps
If the source and Pi can sustain 60 fps, change -r 30 to -r 60 and the two-second GOP example from -g 60 to -g 120. Do not up-convert a 30 fps source just to select 60 fps: that does not create additional motion detail and can waste processing and upload capacity.
Connect to YouTube Live and test
- Open YouTube Live Control Room. Create or select the live event and obtain its RTMPS ingest server address and stream key. Use the key privately; do not expose it in examples or logs.
- Build the FFmpeg input section. Add the correct video and, if needed, audio device arguments for your Pi, OS, and FFmpeg build. Check that FFmpeg recognizes the intended encoder.
- Set output parameters. Use 1280 × 720, a source-appropriate frame rate, H.264, CBR, and a two-second keyframe interval. Keep the bitrate within YouTube’s listed live range and your sustainable upload capacity.
- Start a private or otherwise appropriate test stream. Verify that video and audio arrive correctly and that the picture is not cropped, stretched, or unexpectedly silent.
- Test representative content and watch stream health. YouTube advises testing with audio and movement similar to what you will stream. Check Live Control Room stream health before the event and monitor it while live.
Copyright and channel-policy checks
Using FFmpeg to transmit a video does not grant permission to stream it. Before broadcasting, make sure you have the rights needed for the video, music, and other material in the feed. YouTube’s live-stream checks can flag content, and a technically healthy stream does not establish that the content complies with copyright or channel policies. For a pre-recorded or looping program, consider whether the content and presentation comply with YouTube’s rules on reused content and monetization; passing a live ingest test does not guarantee monetization eligibility.

Troubleshoot common problems
- FFmpeg says the encoder is unknown: Your build may not include the named encoder. Inspect the encoders available in that build and select a supported path; the Pi 4 hardware encoder and Pi 5 software-encoder guidance are not interchangeable.
- The Pi cannot keep up or the stream stutters: Check CPU load, frame drops, and stream health. On Pi 5, software encoding can be demanding; reduce the frame rate to 30, reduce bitrate within YouTube’s live guidance, or simplify the source workflow.
- YouTube reports unstable stream health: The bitrate may exceed steady upstream capacity, or the connection may be varying. Test with motion and audio, then lower the bitrate or frame rate until the feed is stable.
- Video arrives but audio does not: The templates use
-anto make the video-only case explicit. Remove it only when adding the correct audio input and encoder options for your microphone or other source. - YouTube does not receive the stream: Recheck the RTMPS server address and private stream key copied from the current Live Control Room event. Keep the key secret, and confirm that the output format and encoder are supported by your FFmpeg build.
- Latency is too high for the use case: Pi 5 software encoding may introduce more latency than older hardware encoders in some real-time camera cases. Raspberry Pi documents
rpicam-vid --low-latencyas a way to reduce encoding latency, with a coding-efficiency tradeoff; confirm that this camera workflow fits your setup.
