Plugin providing element for converting frame rate of raw video stream.

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

## Installation

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

```elixir

def deps do

  [

    {:membrane_framerate_converter_plugin, "~> 0.8.2"}

  ]

end

```

## Description

Element converts video to target constant frame rate, by dropping and duplicating frames as necessary

(input video may have constant or variable frame rate).

## Usage

Example converting h264 video from 10 to 2 fps.

```elixir

defmodule Pipeline do

  use Membrane.Pipeline

  alias Membrane.H264.FFmpeg.{Decoder, Encoder}

  alias Membrane.H264.Parser

  alias Membrane.File.{Sink, Source}

  @impl true

  def handle_init(_ctx, filename) do

    structure =

        child(file: %Source{chunk_size: 40_960, location: filename})

        |> child(parser: %Parser{generate_best_effort_timestamps: %{framerate: {10, 1}}})

        |> child(decoder: Decoder)

        |> child(converter: %Membrane.FramerateConverter{framerate: {2, 1}})

        |> child(encoder: Encoder)

        |> child(sink: %Sink{location: "output.h264"})

    {[spec: structure], %{}}

  end

end

```
