Question

I would like to know if it’s possible to play a video from an NSData object… with the MPMoviePlayerController.

Ben’s answer works perfectly on simulator but wont work on the device, You cannot write anywhere on the device. Check code below

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *path = [documentsDirectory stringByAppendingPathComponent:@"myMove.mp4"];

    [videoData writeToFile:path atomically:YES];
    NSURL *moveUrl = [NSURL fileURLWithPath:path];
    player = [[MPMoviePlayerController alloc]init];
    [player setContentURL:moveUrl];
    player.view.frame = viewPlayer.bounds;
    [viewPlayer addSubview:player.view];
    [player play];
