FFmpeg Motion

The ffmpeg integration集成将 Home Assistant 与您的设备、服务等连接和集成。 [Learn more] allows you to use any video feed with FFmpeg for motion sensors in Home Assistant.

Note

If the ffmpeg process is broken, the sensor will be unavailable. To control the FFmpeg process of the sensor, use the ffmpeg.start, ffmpeg.stop, and ffmpeg.restart actions.

Motion

FFmpeg doesn’t have a motion detection filter, but can use a scene filter to detect a new scene/motion. You can set how much needs to change in order to detect motion with the option ‘changes’, the percent value of change between frames. If you want a really small value for ‘changes’, you can also add a denoise filter.

Configuration

To add FFmpeg with motion detection to your installation, add the following to your configuration.yamlconfiguration.yaml 文件是 Home Assistant 的主要配置文件。它列出了要加载的集成及其特定配置。在某些情况下，需要直接在 configuration.yaml 文件中手动编辑配置。大多数集成可以在 UI 中配置。 [Learn more] file. 在更改了configuration.yamlconfiguration.yaml 文件是 Home Assistant 的主要配置文件。它列出了要加载的集成及其特定配置。在某些情况下，需要直接在 configuration.yaml 文件中手动编辑配置。大多数集成可以在 UI 中配置。 [Learn more] 文件后，重启 Home Assistant 以应用更改。 该集成现在显示在集成页面的 设置 > 设备与服务 下。其实体在集成卡片上以及实体标签上列出。

Configuration Variables

Looking for your configuration file?
input string Required

An FFmpeg-compatible input file, stream, or feed.

name string (Optional)

Override the name of your camera for the frontend.

initial_state boolean (Optional, default: true)

Start ffmpeg with Home Assistant.

changes integer (Optional, default: 10)

How much needs to change between two frames to detect it as motion, value in percentage (a lower value is more sensitive).

reset integer (Optional, default: 20)

The time to reset the state after no new motion is detected.

repeat integer (Optional, default: 0)

How many events need to be detected in repeat_time in order to trigger a motion, 0 repeats means deactivated.

repeat_time integer (Optional, default: 0)

The span of time repeat events need to occur in before triggering a motion, 0 seconds means deactivated.

extra_arguments string (Optional)

Extra options to pass to ffmpeg, e.g., video denoise filtering.

To experiment with values (changes/100 is the scene value in ffmpeg):

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

If you are running into trouble with this sensor, please refer to the troubleshooting section.

Tips 

extra_arguments: -filter:v "crop=100:100:12:34"
