| # Membrane YOLO Plugin | ||
|
|
||
| [](https://hex.pm/packages/membrane_yolo_plugin) | ||
| [](https://hexdocs.pm/membrane_yolo_plugin) | ||
| [](https://circleci.com/gh/membraneframework/membrane_yolo§ §_plugin) | ||
|
|
||
| Contains 2 Membrane Filters | ||
| - `Membrane.YOLO.LiveFilter` | ||
| - `Membrane.YOLO.OfflineFilter` | ||
| to run YOLO object detection on a video stream in live and offline scaneario. | ||
|
|
||
| Uses under the hood [yolo_elixir](https://github.com/poeticoding/yolo_elixir). | ||
|
|
||
| It's a part of the [Membrane Framework](https://membrane.stream). | ||
|
|
||
| ## Installation | ||
|
|
||
| The package can be installed by adding `membrane_yolo_plugin` to your list of dependencies in `mix.exs`: | ||
|
|
||
| ```elixir | ||
| def deps do | ||
| [ | ||
| {:membrane_yolo_plugin, "~> 0.1.0"} | ||
| ] | ||
| end | ||
| ``` | ||
|
|
||
| ## Examples | ||
|
|
||
| See `examples/yolo.livemd` or `examples/live_camera_capture.exs`, `examples/live_mp4_processing.exs` and `examples/offline_mp4_processing.exs` | ||

There was a problem hiding this comment. I think we should only keep examples in the livebook. It's basically duplicated in this and other .exs scripts, not great for maintenance |
