An Endpoint responsible for converting incoming tracks to HLS playlist. This module requires the following plugins to be present in your mix.exs for H264 & OPUS input:

[
  :membrane_h264_ffmpeg_plugin,
  :membrane_h264_plugin,
  :membrane_http_adaptive_stream_plugin,
  :membrane_opus_plugin,
  :membrane_aac_plugin,
  :membrane_aac_fdk_plugin
]

It can perform mixing audio and composing video (see Membrane.RTC.Engine.Endpoint.HLS.MixerConfig), in such case these plugins are also needed:

[
  :membrane_video_compositor_plugin,
  :membrane_audio_mix_plugin,
  :membrane_generator_plugin,
  :membrane_realtimer_plugin.
  :membrane_audio_filler_plugin
]

• rtc_engine

  pid()

  Required
  Pid of parent Engine

• owner

  pid()

  Required
  Pid of parent all notifications will be send to. These notifications are:

  • {:playlist_playable, content_type}
  • {:cleanup, clean_function}

• output_directory

  Path.t()

  Default value: "hls_output"
  Path to directory under which HLS output will be saved

• synchronize_tracks?

  boolean()

  Default value: true
  Set to false if source is different than webrtc. If set to true HLS Endpoint will calculate track offset based on handle_pad_added call.

• mixer_config

  MixerConfig.t() | nil

  Default value: nil
  Audio and video mixer configuration. If you don't want to use compositor pass nil.

• hls_config

  HLSConfig.t()

  Default value: %Membrane.RTC.Engine.Endpoint.HLS.HLSConfig{manifest_name: "index", manifest_module: Membrane.HTTPAdaptiveStream.HLS, storage: &Membrane.RTC.Engine.Endpoint.HLS.HLSConfig.default_storage/1, target_window_duration: 40000000000, persist?: false, mode: :live, hls_mode: :separate_av, header_naming_fun: &Membrane.HTTPAdaptiveStream.Manifest.Track.default_header_naming_fun/2, segment_naming_fun: &Membrane.HTTPAdaptiveStream.Manifest.Track.default_segment_naming_fun/1, segment_duration: 5000000000, partial_segment_duration: nil}
