Membrane plugin for limiting playback speed to realtime, according to buffers' timestamps.

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

## Installation

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

```elixir

def deps do

  [

    {:membrane_realtimer_plugin, "~> 0.10.0"}

  ]

end

```

## Usage

The following pipeline downloads a sample h264 video via HTTP and sends it in realtime via RTP.

It requires [RTP plugin](https://github.com/membraneframework/membrane_rtp_plugin), [RTP H264 plugin](https://github.com/membraneframework/membrane_rtp_h264_plugin) and [UDP plugin](https://github.com/membraneframework/membrane_udp_plugin) to work.

```elixir

defmodule Example.Pipeline do

  use Membrane.Pipeline

  @ssrc 1234

  @impl true

  def handle_init(_ctx, _opts) do

    structure = [

      child(:source, %Membrane.Hackney.Source{

        location: "https://membraneframework.github.io/static/samples/ffmpeg-testsrc.h264",

        hackney_opts: [follow_redirect: true]

      })

      |> child(:parser, %Membrane.H264.FFmpeg.Parser{framerate: {30, 1}, alignment: :nal})

      |> via_in(Pad.ref(:input, @ssrc), options: [payloader: Membrane.RTP.H264.Payloader])

      |> child(:rtp, Membrane.RTP.SessionBin)

      |> via_out(Pad.ref(:rtp_output, @ssrc), options: [encoding: :H264])

      |> child(:realtimer, Membrane.Realtimer)

      |> child(:sink, %Membrane.UDP.Sink{

        destination_port_no: 5000,

        destination_address: {127, 0, 0, 1}

      })

    ]

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

  end

end

```
