## Installation

The package can be installed by adding `membrane_camera_capture_plugin` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [
	{:membrane_camera_capture_plugin, "~> 0.2.0"}
  ]
end
```

## Sample Usage

Dependencies:

```elixir
def deps do
  [
    {:membrane_core, "~> 0.9.0"},
	{:membrane_camera_capture_plugin, "~> 0.2.0"}
    {:membrane_h264_ffmpeg_plugin, "~> 0.18.0"},
    {:membrane_file_plugin, "~> 0.9.0"},
    {:membrane_ffmpeg_swscale_plugin, "~> 0.8.0"}
  ]
end
```

```elixir
defmodule Example do
  use Membrane.Pipeline

  @impl true
  def handle_init(_) do
    children = [
      source: Membrane.CameraCapture,
      converter: %Membrane.FFmpeg.SWScale.PixelFormatConverter{format: :I420},
      encoder: Membrane.H264.FFmpeg.Encoder,
      sink: %Membrane.File.Sink{location: "output.h264"}
    ]

    links = [
      link(:source)
      |> to(:converter)
      |> to(:encoder)
      |> to(:sink)
    ]

    {{:ok, spec: %ParentSpec{children: children, links: links}}, %{}}
  end
end
```

## Testing

Running this manual test, you should be able to record a 5-sec long video stream from your webcam and then play it using ffplay (you need to have ffmpeg installed).

To run manual tests, you need to install dependencies:

```shell
$ mix deps.get
```

And run manual (you observe the result and decide whether it works) tests:

```shell
$ mix test --include manual
```

If run successfully, you should be able to see video recorded by your camera.
