FFmpeg

The FFmpeg integration allows other Home Assistant integrations to process video and audio streams.

This integration supports all FFmpeg versions since 3.0.0. If you run the Home Assistant Operating System or use the Home Assistant Container, this is already pre-installed for you. In all other cases, make sure you have FFmpeg installed on your system.

Configuration

To set it up, add the following information to your configuration.yamlThe configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI. [Learn more] file:

ffmpeg_bin string (Optional, default: ffmpeg)

The name or path to the ffmpeg binary.

Troubleshooting

In most cases, ffmpeg automatically detects all needed options to read a video or audio stream or file. But it is possible in rare cases that you will need to set options to help ffmpeg out.

First, check that your stream is playable by ffmpeg outside of Home Assistant with (use option -an or -vn to disable video or audio stream):

ffmpeg -i INPUT -an -f null -

Now you should be able to see what is going wrong. The following list contains some common problems and solutions:

  • [rtsp @ ...] UDP timeout, retrying with TCP: You need to set an RTSP transport in the configuration with: input: -rtsp_transport tcp -i INPUT
  • [rtsp @ ...] Could not find codec parameters for stream 0 (Video: ..., none): unspecified size: FFmpeg needs more data or time for autodetection (the default is 5 seconds). You can set the analyzeduration and/or probesize options to experiment with giving FFmpeg more leeway. If you find the needed value, you can set it with: input: -analyzeduration xy -probesize xy -i INPUT. More information about this can be found here.

USB cameras

For INPUT a valid source is needed. A USB camera is an easy way to test your video setup. To get all available USB cameras connected to the system, e.g., use the v4l2 tools on a Linux machine.

$ v4l2-ctl --list-devices
UVC Camera (046d:0825) (usb-0000:00:14.0-1):
  /dev/video1

Integrated Camera (usb-0000:00:14.0-10):
  /dev/video0

Record a test video with your USB device /dev/video1:

$ ffmpeg -i /dev/video1 -codec:v libx264 -qp 0 lossless.mp4
