defmodule Membrane.RTC.Engine.Event.RequestTrackVariant do
@moduledoc """
Event for changing track variant that is currently being received.
Sending this event will cause the engine to send a keyframe request
event to the track origin. Once the engine receives a keyframe
for the requested track variant, it will start forwarding it to
the requester.
If the requested track variant becomes inactive before being delivered
it has to be re-requested when it becomes active again.
See also `Membrane.RTC.Engine.Event.TrackVariantSwitched`.
