The ffmpeg platform allows you to use any video or audio feed with FFmpeg for various sensors in Home Assistant.
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*.
{% linkable_title Configuration %}
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_noise
input: FFMPEG_SUPPORTED_INPUT
{% configuration %}
input:
description: An FFmpeg-compatible input file, stream, or feed.
required: true
type: string
name:
description: Override the name of your camera.
required: false
type: string
initial_state:
description: Start ffmpeg with home-assistant.
required: false
type: boolean
default: true
peak:
description: The threshold of detecting noise, in dB. 0 is very loud and -100 is low.
required: false
type: integer
default: -30
duration:
description: How long the noise needs to be over the peak to trigger the state.
required: false
type: integer
default: 1
reset:
description: The time to reset the state after no new noise is over the peak.
required: false
type: integer
default: 20
extra_arguments:
description: Extra options to pass to ffmpeg, like audio frequency filtering.
required: false
type: string
output:
description: 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.
required: false
type: string
{% endconfiguration %}
To experiment with values:
$ ffmpeg -i YOUR_INPUT -vn -filter:a silencedetect=n=-30dB:d=1 -f null -
