## Usage
The pipeline below displays a sample raw video from file using Membrane raw video parser plugin and 
Membrane SDL plugin.

```elixir
defmodule Membrane.RawVideo.Parser.Pipeline do

  use Membrane.Pipeline

  @doc """
  handle_init(_context, %{
    video_path: String.t(),
    caps: Membrane.RawVideo
  })
  """
  @impl true
  def handle_init(_ctx, options) do
    parser = %Membrane.RawVideo.Parser{
      framerate: options.caps.framerate,
      width: options.caps.width,
      height: options.caps.height,
      pixel_format: options.caps.pixel_format
    }

    structure = [
      child(:file_src, %Membrane.File.Source{location: options.video_path})
      |> child(:parser, parser)
      |> child(:sdl, Membrane.SDL.Player)
    ]

    {[spec: structure, playback: :playing}], %{}}
  end

  @impl true
  def handle_element_end_of_stream(:sdl, _pad_ref, _ctx, state) do
    {[playback: :terminating], state}
  end

  @impl true
  def handle_element_end_of_stream(_src, _pad_ref, _ctx, state) do
    {[], state}
