Question

I built my own custom video player (edit: find example code here) with

AVMoviePlayerView.h

#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>

@class AVPlayer;

@interface AVMoviePlayerView : UIView

@property (nonatomic) AVPlayer *player;

- (void)setPlayer:(AVPlayer*)player;
- (void)setVideoFillMode:(NSString *)fillMode;

@end

and

AVMoviePlayerView.m

#import "AVMoviePlayerView.h"
#import <CoreMedia/CoreMedia.h>

@implementation AVMoviePlayerView


+ (Class)layerClass {

    return [AVPlayerLayer class];

}

- (AVPlayer*)player
{
    return [(AVPlayerLayer*)[self layer] player];
}

- (void)setPlayer:(AVPlayer*)player
{
    [(AVPlayerLayer*)[self layer] setPlayer:player];
}

- (void)setVideoFillMode:(NSString *)fillMode
{
    AVPlayerLayer *playerLayer = (AVPlayerLayer*)[self layer];
    playerLayer.videoGravity = fillMode;
}


@end

calling it from inside my MainViewController.m within -(void)viewDidLoad

    NSURL* url = [[NSBundle mainBundle] URLForResource:@"myVideo.264" withExtension:@"mp4"]; 
    self.avPlayer = [AVPlayer playerWithURL:url];
    [avPlayer addObserver:self forKeyPath:@"status" options:0 context:AVMoviePlayerViewControllerStatusObservationContext];
    [[NSNotificationCenter defaultCenter]   addObserver:self
                                               selector:@selector(playerItemDidReachEnd:)
                                                   name:AVPlayerItemDidPlayToEndTimeNotification
                                                 object:[self.avPlayer currentItem]];

with methods

- (void)observeValueForKeyPath:(NSString*) path ofObject:(id)object change:(NSDictionary*)change context:(void*)context
{
    if (avPlayer.status == AVPlayerStatusReadyToPlay) {
        [self.VideoLoop setPlayer:self.avPlayer];
        [self.avPlayer play];
    }
}
- (void)playerItemDidReachEnd:(NSNotification *)notification {
    AVPlayerItem *p = [notification object];
    [p seekToTime:kCMTimeZero];
}

and of course defined in MainViewController.h

...
#import <CoreGraphics/CoreGraphics.h>
#import "AVMoviePlayerView.h"
@class AVMoviePlayerView;
@class AVPlayer;
...
IBOutlet AVMoviePlayerView *VideoLoop;
AVPlayer* avPlayer;

It works fine in Simulator (except the loop, but thats a different problem) but on the device (iPad3) no video shows up.

Did I miss anything?
Thanx!!!

EDIT: TO make it easier toshow me how stupid I am please find here some esample code. this does work in the simulator but not on device.

Reason found – costs me only 50 points…
iOS supports MPEG-4 video up to 2.5 Mbps, and H.264 1080p. My video frame size was too big!
