A bin responsible for doing framerate conversion on all input videos and piping them into the compositor element.

Bin options

Passed via struct Membrane.VideoCompositor.t/0

• output_stream_format

  Membrane.RawVideo.t()

  Required
  Stream format for the output video of the compositor

• handler

  Handler.t()

  Required
  Module implementing callbacks reacting to VC events. Specifies how Membrane.VideoCompositor.Scene should look like. Describes what VC should compose.

• queuing_strategy

  QueueingStrategy.t()

  Default value: Membrane.VideoCompositor.QueueingStrategy.Offline
  Specifies used frames queueing strategy

• metadata

  init_metadata()

  Default value: nil
  User-specified init metadata passed to handler callbacks. Passing init metadata into Membrane.VideoCompositor.Handler.handle_init/1 callback allows the user to alternate custom-implemented init callback logic.

Pads

:input

Accepted formats:

%RawVideo{pixel_format: :I420}

Pad options:

• timestamp_offset

  Membrane.Time.non_neg()

  Default value: 0
  Input stream PTS offset in nanoseconds. Must be non-negative.

• metadata

  input_pad_metadata()

  Default value: nil
  User-specified input stream metadata passed to handler callbacks. Passing pad metadata into Membrane.VideoCompositor.Handler.handle_inputs_change/3 callback, allows the user to alternate custom-implemented callbacks logic, e.g. prioritizing input stream in the Membrane.VideoCompositor.Scene structs returned from callback.

:output

Accepted formats:

%RawVideo{pixel_format: :I420}
