The ffmpeg platform allows you to use every 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 the instance, use the service binary_sensor.ffmpeg_restart.

You need the `ffmpeg` binary in your system path. On Debain 8 you can install it from backports. If you want Hardware support on a Raspberry Pi you need to build it from source. Windows binary are avilable on [FFmpeg](http://www.ffmpeg.org/) homepage.

{% linkable_title Noise %}

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

# Example configuration.yaml entry
camera:
  - platform: ffmpeg
    tool: noise
    input: FFMPEG_SUPPORTED_INPUT
    name: FFmpeg Noise
    ffmpeg_bin: /usr/bin/ffmpeg
    peak: -30
    duration: 1
    reset: 20

Configuration variables:

• input (Required): A ffmpeg compatible input file, stream or feed.
• tool (Required): Is fix set to noise.
• name (Optional): This parameter allows you to override the name of your camera.
• 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): Defaults to 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, like audio frequence filtering.
• output (Optional): Allow you to send the audio output of this sensor to an icecast server or other ffmpeg supported output, eg. to stream with sonos after state is triggered.

For playing 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, so it uses a scene filter to detect a new scene/motion. In fact, you can set how big of an object or the size of an image that needs to change in order to detect motion. The option 'changes' is the percent value of change between frames. You can add a denoise filter to the video if you want a really small value for 'changes'.

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

# Example configuration.yaml entry
camera:
  - platform: ffmpeg
    tool: motion
    input: FFMPEG_SUPPORTED_INPUT
    name: FFmpeg Motion
    ffmpeg_bin: /usr/bin/ffmpeg
    changes: 10
    reset: 20
    # group feature / default not in use
    repeat: 0
    repeat_time: 0
    

Configuration variables:

• input (Required): A ffmpeg compatible input file, stream, or feed.
• tool (Required): Is fix set to motion.
• name (Optional): This parameter allows you to override the name of your camera.
• ffmpeg_bin (Optional): Default ffmpeg.
• changes (Optional): Default 10 percent. A lower value is more sensitive. I use 4 / 3.5 on my cameras. It describes how much needs to change between two frames to detect it as motion. See on descripton.
• 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 option they will pass to ffmpeg. i.e. video denoise filtering.

For playing with values (changes/100 is the scene value on ffmpeg):

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