This package provides an element parsing a data stream into raw (uncompressed) video frames.

Documentation is available at [HexDocs](https://hexdocs.pm/membrane_raw_video_parser_plugin/)

It is part of [Membrane Multimedia Framework](https://membrane.stream/).

## Installation

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

```elixir

	{:membrane_raw_video_parser_plugin, "~> 0.12.2"}

```

## 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}

  end

end

```
