FFmpeg Noise Binary Sensor


The ffmpeg platform allows you to use any video or audio feed with FFmpeg for various sensors in Home Assistant.

If the ffmpeg process is broken, the sensor will be unavailable. To controll the ffmpeg process of sensor, use the service ffmpeg.start, ffmpeg.stop, ffmpeg.restart.

Noise

To add FFmpeg with noise detection to your installation, add the following to your configuration.yaml file:

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

Configuration variables:

  • input (Required): An FFmpeg-compatible input file, stream, or feed.
  • name (Optional): Override the name of your camera.
  • initial_state (Optional): Default true. Start ffmpeg with home-assistant.
  • peak (Optional): Default -30. The threshold of detecting noise, in dB. 0 is very loud and -100 is low.
  • duration (Optional): Default 1 second. How long the noise needs to be over the peak to trigger the state.
  • reset (Optional): Default 20 seconds. The time to reset the state after no new noise is over the peak.
  • extra_arguments (Optional): Extra options to pass to ffmpeg, like audio frequency filtering.
  • output (Optional): Allows you to send the audio output of this sensor to an Icecast server or other FFmpeg-supported output, e.g. to stream with Sonos after a state is triggered.

To experiment with values:

$ ffmpeg -i YOUR_INPUT -vn -filter:a silencedetect=n=-30dB:d=1 -f null -
