The `ffmpeg` platform allows you to use any video or audio feed with [FFmpeg](http://www.ffmpeg.org/) for various sensors in Home Assistant.
|
|
|
|
<p class='note'>
|
|
If the `ffmpeg` process is broken, the sensor will be unavailable. To control the ffmpeg process of sensor, use the service *ffmpeg.start*, *ffmpeg.stop*, *ffmpeg.restart*.
