MPMoviePlayerController shows blank screen or crashes app - ios

Question

I have a UIViewController subclass called videoPlayerViewController.
In storyboard I dragged out a UIViewController. I set the class correctly in Storyboard.
I put a button on the screen. When I click the button, it executes the method playVideo:.
- (IBAction)playVideo:(id)sender
{
NSURL *movieURL = [NSURL URLWithString:#"http://www.ebookfrenzy.com/ios_book/movie/movie.mov"];
MPMoviePlayerController *player =
[[MPMoviePlayerController alloc] initWithContentURL: movieURL];
[player prepareToPlay];
[player.view setFrame: self.view.bounds]; // player's frame must match parent's
[self.view addSubview: player.view];
[player play];
}
I get a black screen that does nothing.
This is the simplest version of the code I've had in this method over the last 6 hours.
I've tried every StackOverflow answer out there.
I just want to play a video that I stream from the internet.
If I set:
player.movieSourceType = MPMovieSourceTypeStreaming;
the screen reads "loading" for a second, and then crashes.
What exactly am I doing wrong?
I understand there are so many MPMoviePlayerController questions out there, and to just ask a general "How does it work" question seems ludicrous. I've been at this almost 6 hours now and no Google/Stack Overflow/Apple Documentation search has made this work.

Answer 1

I used your provided code but created a MoviePlayerController property named mcp in the header file that I assigned to player to after creating it. That worked for me. The movie loaded and played just fine.
In the .h file:
#property (strong, nonatomic) MPMoviePlayerController *mcp;
In the .m file:
- (IBAction)playVideo:(id)sender
{
NSURL *movieURL = [NSURL URLWithString:#"http://www.ebookfrenzy.com/ios_book/movie/movie.mov"];
MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL: movieURL];
[player prepareToPlay];
[player.view setFrame: self.view.bounds]; // player's frame must match parent's
_mcp = player;
[self.view addSubview: _mcp.view];
[_mcp play];
}
