The `ffmpeg` platform allows you to use every video or audio feed with [FFmpeg](http://www.ffmpeg.org/) as varius sensors in Home Assistant. Avilable are: **noise**, **motion**. If ffmpeg process is brocken, sensor going to unavilable. It exists a service to restart a instance with *binary_sensor.ffmpeg_restart*.

You need a ffmpeg binary in your system path. On debain 8 you can install it from backports. If you want HW support on raspberry you need self build from source. Windows binary are avilable on ffmpeg homepage.

- **ffmpeg_bin** (*Optional*): Default `ffmpeg`.
|
||||
- **peak** (*Optional*): Default -30. A peak of dB to detect it as noise. 0 is very loud and -100 is low.
|

- **duration** (*Optional*): Default 1 seconds. How long need the noise over the peak to trigger the state.

- **reset** (*Optional*): Default 20 seconds. The time to reset the state after none new noise is over the peak.
|

- **extra_arguments** (*Optional*): Extra option they will pass to ffmpeg. i.e. audio frequence filtering.
|

- **output** (*Optional*): Allow you to send the audio output of this sensor to a icecast server or other ffmpeg supported output. i.e. to stream with sonos after state is trigger.

- **reset** (*Optional*): Defaults to 20 seconds. The time to reset the state after none new noise is over the peak.

### {% linkable_title Motion %}

FFmpeg don't have a motion detection filter so it use a scene filter to detect a new scene/motion. In fact you can set how big a object or size of image they need change to detect a motion. The option 'changes' is the percent value of change between frames. You can add a denoice filter to video if you want a realy small value for 'changes'.
