how to add video to app - iphone

Question

I'm trying to make an app that plays a video, and I'm having problems. I hear the sound but see no video. I have sincerely tried looking around for a solution, but all the tips don't seem to work. Here's the code:
VideoTestViewController.m
#import "VideoTestViewController.h"
#implementation VideoTestViewController
// Implement loadView to create a view hierarchy programmatically, without using a nib.
- (void)loadView {
NSString *moviePath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"spitfiregrill_iPhone.m4v"];
MPMoviePlayerController *theMovie = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:moviePath]];
theMovie.controlStyle = MPMovieControlStyleDefault;
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(movieFinishedCallback:) name:MPMoviePlayerPlaybackDidFinishNotification object:theMovie];
[theMovie play];
}
/*
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
}
*/
/*
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
*/
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
- (void)viewDidUnload {
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)dealloc {
[super dealloc];
}
#end
VideoTestViewController.h
#import <UIKit/UIKit.h>
#import <MediaPlayer/MediaPlayer.h>
#interface VideoTestViewController : UIViewController {
}
#end

- (void)viewDidLoad {
NSString *url = [[NSBundle mainBundle]
pathForResource:#"Stock_Footage_Demobroadband"
ofType:#"mp4"];
MPMoviePlayerController *player =
[[MPMoviePlayerController alloc]
initWithContentURL:[NSURL fileURLWithPath:url]];
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:#selector(movieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:player];
//---play partial screen---
player.view.frame = CGRectMake(184, 200, 400, 300);
[self.view addSubview:player.view];
//---play movie---
[player play];
[super viewDidLoad];
}
- (void) movieFinishedCallback:(NSNotification*) aNotification {
MPMoviePlayerController *player = [aNotification object];
[[NSNotificationCenter defaultCenter]
removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:player];
[player stop];
[self.view removeFromSuperView];
[player autorelease];
}
Video in full screen mode -
- (void)viewDidLoad {
NSString *url = [[NSBundle mainBundle]
pathForResource:#"Stock_Footage_Demobroadband"
ofType:#"mp4"];
MPMoviePlayerViewController *playerViewController =
[[MPMoviePlayerViewController alloc]
initWithContentURL:[NSURL fileURLWithPath:url]];
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:#selector(movieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:[playerViewController moviePlayer]];
[self.view addSubview:playerViewController.view];
//---play movie---
MPMoviePlayerController *player = [playerViewController moviePlayer];
[player play];
[super viewDidLoad];
}
- (void) movieFinishedCallback:(NSNotification*) aNotification {
MPMoviePlayerController *player = [aNotification object];
[[NSNotificationCenter defaultCenter]
removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:player];
[player stop];
[self.view removeFromSuperView];
[player autorelease];
}

A bit of guesswork - but this is what I'd do:
VideoTestViewController.h
#import <UIKit/UIKit.h>
#import <MediaPlayer/MediaPlayer.h>
#interface VideoTestViewController : UIViewController
{
MPMoviePlayerController* m_player;
}
- (void) play;
#end
VideoTestViewController.m
#implementation VideoTestViewController
- (void) viewDidAppear:(BOOL)animated
{
[self play];
}
- (void) play
{
NSURL* url = [[NSBundle mainBundle] URLForResource:#"spitfiregrill_iPhone" withExtension:#"m4v"];
m_player = [[MPMoviePlayerController alloc] initWithContentURL:url];
[m_player.backgroundView setBackgroundColor:[UIColor blackColor]];
[m_player.view setBackgroundColor:[UIColor blackColor]];
[m_player setControlStyle:MPMovieControlStyleNone];
[[m_player view] setFrame:[self.view bounds]];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
[m_player play];
[self.view addSubview:[m_player view]];
}
- (void) moviePlayBackDidFinish:(NSNotification*)_notification
{
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:nil];
[m_player.view removeFromSuperview];
[m_player stop];
[m_player release];
m_player = nil;
}
#end
