+
+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*.
+
+<p class='note'>
+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.
+</p>
+
+### {% linkable_title Noise %}
+
+To enable your FFmpeg with noise detection in your installation, add the following to your `configuration.yaml` file:
+
+```yaml
+# 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*): 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.
+
+For playing with values:
+```bash
+ffmpeg -i YOUR_INPUT -vn -filter:a silencedetect=n=-30dB:d=1 -f null -
+```
+
+### {% 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'.
+
+To enable your FFmpeg with motion detection in your installation, add the following to your `configuration.yaml` file:
+
+```yaml
+# 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 describe how mutch of two frames need to change to detect it as motion. See on descripton.
+- **reset** (*Optional*): Default 20 seconds. The time to reset the state after none new motion is detect.
+- **repeat** (*Optional*): Default 0 repeats (deactivate). How many motion need to detect in *repeat_time* to trigger a motion.
+- **repeat_time** (*Optional*): Default 0 seconds (deactivate). The time to repeats befor it trigger 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):
+```bash
+ffmpeg -i YOUR_INPUT -an -filter:v select=gt(scene\,0.1) -f framemd5 -
+```
