Membrane H.264 and H.265 parsers.

It is a pair of Membrane elements responsible for parsing the incoming H.264 and H.265 streams. The parsing is done as a sequence of the following steps:

* splitting the stream into stream NAL units

* Parsing the NAL unit headers, so that to read the type of the NAL unit

* Parsing the NAL unit body with the appropriate scheme, based on the NAL unit type read in the step before

* Aggregating the NAL units into a stream of *access units*

The output of the element is the incoming binary payload, enriched with the metadata describing the division of the payload into *access units*.

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

## Installation

The package can be installed by adding `membrane_h26x_plugin` to your list of dependencies in `mix.exs`:

```elixir

def deps do

  [

    {:membrane_h26x_plugin, "~> 0.10.2"}

  ]

end

```

## Usage

The following pipeline takes H264 file, parses it, and then decodes it to the raw video.

```elixir

defmodule Decoding.Pipeline do

  use Membrane.Pipeline

  alias Membrane.{File, H264}

  @impl true

  def handle_init(_ctx, _opts) do

    spec =

      child(:source, %File.Source{location: "test/fixtures/input-10-720p-main.h264"})

      |> child(:parser, H264.Parser)

      |> child(:decoder, H264.FFmpeg.Decoder)

      |> child(:sink, %File.Sink{location: "output.raw"})

    {[spec: spec], nil}

  end

  @impl true

  def handle_element_end_of_stream(:sink, _ctx_, state) do

    {[terminate: :normal], state}

  end

end

```
