This plugin can be used to capture video stream from an input device.

It is part of [Membrane Multimedia Framework](https://membraneframework.org).

## 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, "~> 0.4.0"}
  ]
end
```

## Sample Usage

Dependencies:

```elixir
def deps do
  [
    {:membrane_camera_capture_plugin, "~> 0.4.0"},
    {:membrane_h264_ffmpeg_plugin, "~> 0.21"},
    {:membrane_file_plugin, "~> 0.10"},
    {:membrane_ffmpeg_swscale_plugin, "~> 0.10"}
  ]
end
```

```elixir
defmodule Example do
  use Membrane.Pipeline

  @impl true
  def handle_init(_ctx, _options) do
    structure = 
      child(:source, Membrane.CameraCapture) 
      |> child(:converter, %Membrane.FFmpeg.SWScale.PixelFormatConverter{format: :I420}) 
      |> child(:encoder, Membrane.H264.FFmpeg.Encoder) 
      |> child(:sink, %Membrane.File.Sink{location: "output.h264"}) 

    {[spec: structure], %{}}
  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.
