MPMoviePlayerController switching videos - ios

Question

I'm playing a video:
let path = NSBundle.mainBundle().pathForResource("Video", ofType:"mp4")
let url = NSURL.fileURLWithPath(path!)
moviePlayer = MPMoviePlayerController(contentURL: url)
if let player = moviePlayer {
player.view.frame = self.view.bounds
player.prepareToPlay()
player.scalingMode = .AspectFill
player.controlStyle = .None
self.view.addSubview(player.view)
}
and I want to replace this with another video when a button is pressed:
#IBAction func aButtonIsPressed(sender: AnyObject) {
let path = NSBundle.mainBundle().pathForResource("Another Video", ofType:"mp4")
let url = NSURL.fileURLWithPath(path!)
moviePlayer = MPMoviePlayerController(contentURL: url)
if let player = moviePlayer {
player.view.frame = self.view.bounds
player.prepareToPlay()
player.scalingMode = .AspectFill
player.controlStyle = .None
self.view.addSubview(player.view)
}
}
When I tap the button the video plays, but there seems to be a delay adding the new video, which gives it a choppy transition. Is there any way to minimize this delay? I could try adding another MPMoviePlayerController to preload the second video maybe but from some testing I found the line causing the chop is here.
self.view.addSubview(player.view)
Can I keep the first video playing until the line above 'didFinish'? That would be great.

Answer 1

You are creating new MPMoviePlayerController object that's why you are getting this issue, you should use same object and which is already playing an object and just set contentURL property to new resource's URL,
If you set this property while a movie is playing, that movie pauses
and the new movie begins loading. The new movie starts playing at the
beginning
