How to Install FFmpeg on Raspberry Pi OS for a YouTube Loop Stream

Use APT to install FFmpeg on Raspberry Pi OS, then configure a looping file for YouTube Live with a private stream key and settings your Pi can sustain.

Install FFmpeg from Raspberry Pi OS’s APT repositories with sudo apt update followed by sudo apt install ffmpeg. That installs the encoder; it does not start a YouTube broadcast. To stream a looping file, you also need a compatible video, YouTube’s stream URL and private stream key, suitable encoding settings, and enough Pi and internet capacity to sustain them.

Install FFmpeg on Raspberry Pi OS

  1. Open a terminal on the Raspberry Pi, or connect to it remotely over SSH.

  2. Refresh the package lists: sudo apt update. Raspberry Pi OS uses APT to manage software, and its documentation recommends updating package lists before installing packages. See the Raspberry Pi OS documentation.

  3. Install FFmpeg: sudo apt install ffmpeg. Raspberry Pi’s camera documentation also uses this command to install FFmpeg: Raspberry Pi camera software documentation.

  4. Check that the executable is available: ffmpeg -version. The command should print version and build information. This confirms that FFmpeg is installed, but not that the Pi can encode your chosen stream in real time.

The package version and available encoders depend on the OS image, architecture, repositories, and installed build; there is no single version guaranteed for every Pi installation. If APT says it cannot locate the package, first check that the Pi has internet access and that its configured Raspberry Pi OS repositories are enabled. Avoid downloading an arbitrary FFmpeg binary as the default fix.

What you need before sending a loop to YouTube

Treat the stream key like a password. Do not publish it in an article, screenshot, shell history, source-control repository, or a command you share. If it is exposed, replace or reset it in YouTube Studio.

Choose settings the Pi and connection can sustain

YouTube’s current encoder guidance supports RTMP or RTMPS ingest, H.264, H.265/HEVC, or AV1 video, AAC or MP3 audio, and frame rates up to 60 fps. It calls for constant bitrate (CBR), recommends a two-second keyframe interval, and says not to exceed four seconds. YouTube recommends RTMPS for encrypted transport. Check the YouTube encoder settings and verify that your installed FFmpeg build supports the encoder and protocol you intend to use.

Example target YouTube H.264 bitrate guidance What the figure means
720p at 30 fps 3 Mbps minimum; 8 Mbps recommended YouTube ingest guidance, not a Raspberry Pi performance guarantee.
1080p at 30 fps 5 Mbps minimum; 14 Mbps recommended YouTube ingest guidance, not a Raspberry Pi performance guarantee.

These bitrate recommendations are from YouTube’s encoder settings guidance, accessed in 2026, and may change. They do not establish whether a particular Pi can encode the source at that rate. Start with a modest target, then test the actual model, file, and FFmpeg build. YouTube also recommends leaving 20% upload headroom, using a reliable connection, and monitoring stream health; see its live streaming tips. Account for audio bitrate as part of the total upload load.

Build and test a looping FFmpeg stream

The example below assumes a local file named documentary.mp4 that contains video and audio, a Pi capable of encoding H.264 in real time at the selected settings, and an FFmpeg build with the required encoder and RTMPS support. It uses libx264 and AAC as an example; available encoders vary by build. This is a template, not a command tested on every Raspberry Pi model.

  1. Find YouTube’s stream URL and key in the Live Control Room. Put the key in a protected environment variable rather than typing it into a command that may remain in shell history. For example, in a Bash session: read -s YT_KEY, enter the key when prompted, then press Enter. The variable lasts only for that shell session.

  2. Run a private or unlisted test broadcast and replace the URL placeholder with YouTube’s actual RTMPS ingest URL:

    Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

    ffmpeg -re -stream_loop -1 -i documentary.mp4 -c:v libx264 -preset veryfast -b:v 3000k -maxrate 3000k -bufsize 6000k -pix_fmt yuv420p -r 30 -g 60 -keyint_min 60 -sc_threshold 0 -c:a aac -b:a 128k -ar 44100 -f flv "RTMPS_URL/${YT_KEY}"

    Here -stream_loop -1 repeats the input indefinitely, -re reads it at approximately real-time speed, and -g 60 with a 30 fps output sets a two-second GOP/keyframe interval. The 3,000 kbps video target corresponds to YouTube’s stated 720p/30 H.264 minimum, not its recommended bitrate; use a suitable resolution and bitrate for your source, Pi, and connection. The example does not scale the video, so output dimensions follow the input. Confirm the exact RTMPS URL format and any stream-key placement with the URL YouTube provides for your encoder.

  3. Watch FFmpeg’s output and YouTube Studio’s stream health while the test runs. Check for encoder overload, dropped frames, connection instability, working audio, and a clean transition when the file loops. If the Pi cannot sustain real-time encoding, reduce resolution, frame rate, or encoding workload, or use a more capable device.

If the input has no audio track, this example’s audio settings may fail. Inspect the file first (for example, with ffprobe, if installed) and adapt the command to omit audio encoding or map an appropriate audio source. Do not assume that every file contains audio or that every FFmpeg build offers libx264. Use ffmpeg -encoders and ffmpeg -protocols to inspect the installed build.

Troubleshoot common failures

  • APT cannot locate FFmpeg: verify connectivity, run sudo apt update again, and check the enabled Raspberry Pi OS repositories and release configuration.

  • “Unknown encoder” or “Protocol not found”: the installed build may lack libx264, AAC support, or RTMPS support. Inspect the available encoders and protocols; use a supported option or an appropriate Raspberry Pi OS package build.

  • YouTube shows no incoming video: verify the exact ingest URL and key, that the stream is started in the Live Control Room, and that the network permits the outgoing connection. Keep the key private and replace it if it was exposed.

    • 【More Connectors】There are two USB 3.0 ports(5Gbps simultaneously) and two USB 2.0 ports, which triple total bandwidth ,support any combination of up to two cameras or displays. Peak SD card performance is doubled through support for the SDR104 high-speed mode. It provides a smooth desktop experience for you. Offer Gigabit Ethernet and a PCIe interface, along with dual-band Wi-Fi and Bluetooth 5.0/BLE wireless capability. The RasTech Pi 5 Kit use the new 27W 5.1V 5A USB-C power connector.
    • 【 Support Dual 4Kp60 Display 】Each of the two microHDMI sockets can control a 4K display at 60 Hertz, now support HDR, offering super HD video for media streaming projects. RPi 5 is the first RPi model that comes with a PCI Express port (PCIe 2.0 x1 with 500 MB/s) to attach SSDs (requires separate M.2 HAT).
    • 【 Excellent Chips And Applications】Pi 5 is a full-size Pi computer using silicon built in-house at Pi. The RP1 “southbridge” provides the bulk of the I/O capabilities for Pi 5. Pi 5 is more friendly and convenient in the development of Internet of Things, Web development, machine identification, automatic control and other electronic equipment applications and network.
    • 【 Faster CPU, Better GPU 】 Pi 5 features a Broadcom BCM2712 64-bit quad-core Arm Cortex-A76 processor running at 2.4GHz, it delivers a 2–3× increase in CPU performance relative to RaspberryPi 4. The 800MHz VideoCore VII GPU is compatible to OpenGL ES 3.1 and Vulkan 1.2, substantial uplift in graphics performance. Pi 5 Offers lightning-fast CPU speed, a PCI Express interface, a Real Time Clock (RTC) and a power button and runs significantly cooler than Pi 4.
  • Dropped frames or unstable stream health: the upload connection may be unreliable or lack headroom, or the Pi may be overloaded. Lower the target bitrate or encoding workload, use wired networking if available, and monitor both FFmpeg output and YouTube’s stream-health indicator.

  • Audio is missing or FFmpeg exits at startup: check whether the source actually has an audio stream and adjust audio mapping and encoding accordingly.

  • The stream stops when the Pi loses power or the process exits: FFmpeg runs on the Pi, so it depends on that device, its power, network, and process remaining available. A service manager can restart a process after some failures, but cannot keep an unpowered or disconnected Pi online.
