Issue

I am mainly opening this issue to track the state of this. I am planning on fixing this myself.

Description

When setting the playback speed before initializing or when seeking, the playback speed is reset on the actual video (the video player value on the Flutter side has the set speed but the underlying player does not):

VideoPlayerController(..)
  ..setPlaybackSpeed(2) // This is ignored by the underlying player on iOS.
  ..initialize();

controller.seekTo(..); // This will also reset the playback speed on iOS.

Doctor

video_player: 1.0.1
