The ffmpeg {% term integration %} allows you to use any video feed with FFmpeg for motion sensors in Home Assistant.

{% note %}

If the ffmpeg process is broken, the sensor will be unavailable. To control the FFmpeg process of the sensor, use the ffmpeg.start, ffmpeg.stop, and ffmpeg.restart actions.

{% endnote %}

Motion

FFmpeg doesn't have a motion detection filter, but can use a scene filter to detect a new scene/motion. You can set how much needs to change in order to detect motion with the option 'changes', the percent value of change between frames. If you want a really small value for 'changes', you can also add a denoise filter.

Configuration

To add FFmpeg with motion detection to your installation, add the following to your {% term "configuration.yaml" %} file. {% include integrations/restart_ha_after_config_inclusion.md %}

# Example configuration.yaml entry
binary_sensor:
  - platform: ffmpeg_motion
    input: FFMPEG_SUPPORTED_INPUT

{% configuration %} input: description: An FFmpeg-compatible input file, stream, or feed. required: true type: string name: description: Override the name of your camera for the frontend. required: false type: string initial_state: description: Start ffmpeg with Home Assistant. required: false type: boolean default: true changes: description: How much needs to change between two frames to detect it as motion, value in percentage (a lower value is more sensitive). required: false type: integer default: 10 reset: description: The time to reset the state after no new motion is detected. required: false type: integer default: 20 repeat: description: How many events need to be detected in repeat_time in order to trigger a motion, 0 repeats means deactivated. required: false type: integer default: 0 repeat_time: description: The span of time repeat events need to occur in before triggering a motion, 0 seconds means deactivated. required: false type: integer default: 0 extra_arguments: description: Extra options to pass to ffmpeg, e.g., video denoise filtering. required: false type: string {% endconfiguration %}

To experiment with values (changes/100 is the scene value in ffmpeg):

ffmpeg -i YOUR_INPUT -an -filter:v select=gt(scene\,0.1) -f framemd5 -

If you are running into trouble with this sensor, please refer to the troubleshooting section.
