# Membrane Camera Capture Plugin

[![API Docs](](

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

It is part of [Membrane Multimedia Framework](

## Installation

Add the following line to your `deps` in `mix.exs`. Run `mix deps.get`.

  {:membrane_camera_capture_plugin, "~> 0.6.1"}

This package depends on the [ffmpeg]( libraries. The precompiled builds will be pulled and linked automatically. However, should there be any problems, consider installing it manually.

### Manual instalation of dependencies
#### Ubuntu

sudo apt-get install ffmpeg

#### Arch/Manjaro

pacman -S ffmpeg

#### MacOS

brew install ffmpeg

## Sample Usage


def deps do
	{:membrane_camera_capture_plugin, "~> 0.5.0"}
    {:membrane_h264_ffmpeg_plugin, "~> 0.21"},
    {:membrane_file_plugin, "~> 0.10"},
    {:membrane_ffmpeg_swscale_plugin, "~> 0.10"}

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], %{}}

## 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:

$ mix deps.get

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

$ mix test --include manual

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

_You might be asked to grant access to your camera, as some operating systems require that_

_In case of the absence of a physical camera, it is necessary to use a virtual camera (e.g. OBS, [see how to set up the virtual camera in OBS](
