Membrane Rpicam Plugin allows capturing video from official RaspberryPi camera module using [rpicam-apps](https://github.com/raspberry-pi/rpicam-apps) (formerly libcamera-apps). This plugin can also be used on devices running [Nerves](https://nerves-project.org).

## Installation

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

```elixir

def deps do

  [

    {:membrane_rpicam_plugin, "~> 0.1.5"}

  ]

end

```

The package depends on rpicam-apps that need to be present on the target system.

## Usage

The following script creates and starts a pipeline capturing 5 seconds from the RaspberryPi camera module and saving it to `/data/output.h264`:

```elixir

defmodule Rpicam.Pipeline do

  use Membrane.Pipeline

  

  @impl true

  def handle_init(_ctx, _opts) do

    spec =   

      child(:source, %Membrane.Rpicam.Source{timeout: 5000})

      |> child(:sink, %Membrane.File.Sink{location: "/data/output.h264"})

    {[spec: spec], %{}}

  end

  @impl true

  def handle_element_end_of_stream(:sink, _pad, _ctx, state) do

    {[terminate: :normal], state}

  end

  @impl true

  def handle_element_end_of_stream(_child, _pad, _ctx, state) do

    {[], state}

  end

end

# Start and monitor the pipeline

{:ok, _supervisor_pid, pipeline_pid} = Membrane.Pipeline.start_link(Rpicam.Pipeline)

ref = Process.monitor(pipeline_pid)

# Wait for the pipeline to finish

receive do

  {:DOWN, ^ref, :process, _pipeline_pid, _reason} ->

    :ok

end

```
