The ffmpeg platform allows you to use any video or audio feed with FFmpeg for various sensors in Home Assistant. Available are: noise, motion.

If the `ffmpeg` process is broken, the sensor will be unavailable. To restart it, use the service *binary_sensor.ffmpeg_restart*.

{% linkable_title 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
    tool: noise

Configuration variables:

• input (Required): An FFmpeg-compatible input file, stream, or feed.
• tool (Required): noise.
• name (Optional): Override the name of your camera.
• 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 -

{% linkable_title 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.

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

# Example configuration.yaml entry
binary_sensor:
  - platform: ffmpeg
    tool: motion
    input: FFMPEG_SUPPORTED_INPUT

Configuration variables:

• input (Required): An FFmpeg-compatible input file, stream, or feed.
• tool (Required): motion.
• name (Optional): Override the name of your camera.
• changes (Optional): Default 10%. How much needs to change between two frames to detect it as motion (a lower value is more sensitive).
• reset (Optional): Default 20 seconds. The time to reset the state after no new motion is detected.
• repeat (Optional): Default 0 repeats (deactivate). How many events need to be detected in repeat_time in order to trigger a motion.
• repeat_time (Optional): Default 0 seconds (deactivate). The span of time repeat events need to occur in before triggering a motion.
• extra_arguments (Optional): Extra options to pass to FFmpeg, e.g. video denoise filtering.

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.

• Use motion only in a customer area with crop filter: extra_arguments: -filter:v "crop=100:100:12:34"
