Cocos2d：如何在CCLayer的背景下播放视频 [英] Cocos2d: How to play a video in the background of a CCLayer

问题描述

我想在背景播放视频，并在正文的文本标签中运行以下代码，正在播放视频，但文字标签不显示！

   - （id）init {
 if（！（self = [super init]））{
 return nil; 
} 
 
 CGSize size = [[CCDirector sharedDirector] winSize]; 
 
 // MP4 
 NSURL * url = [NSURL fileURLWithPath：[[NSBundle mainBundle] pathForResource：@testofType：@m4v]]; 
 moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL：url]; 
 [moviePlayer respondingToSelector：@selector（setFullscreen：animated :)]; 
 moviePlayer.controlStyle = MPMovieControlStyleNone; 
 moviePlayer.shouldAutoplay = YES; 
 moviePlayer.repeatMode = MPMovieRepeatModeOne; 
 moviePlayer.view.frame = CGRectMake（0，0，size.height，size.width）; 
 [viewController.view addSubview：moviePlayer.view]; 
 [viewController.view sendSubviewToBack：moviePlayer.view]; 
 
 //创建和初始化标签
 CCLabelTTF * label = [CCLabelTTF labelWithString：@Hello WorldfontName：@Marker FeltfontSize：64]; 
 label.position = ccp（size.width / 2，size.height / 2）; 
 [self addChild：label]; 
 
 return self; 
} 
  

解决方案

/ p>

首先在AppDelegate.m中用kEAGLColorFormatRGBA8替换kEAGLColorFormatRGB565，其次，如下面的代码，最后4行很重要：

  NSURL * url = [NSURL fileURLWithPath：[[NSBundle mainBundle] pathForResource：@videoofType：@mp4]]; 
 _moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL：url]; 
 [[NSNotificationCenter defaultCenter] addObserver：self 
 selector：@selector（moviePlayBackDidFinish）
 name：MPMoviePlayerPlaybackDidFinishNotification 
 object：_moviePlayer]; 
 
 [_moviePlayer respondingToSelector：@selector（setFullscreen：animated :)]; 
 _moviePlayer.controlStyle = MPMovieControlStyleNone; 
 _moviePlayer.shouldAutoplay = YES; 
 _moviePlayer.repeatMode = MPMovieRepeatModeOne; 
 _moviePlayer.view.frame = CGRectMake（0，0，300，300）; 
 
 UIView * glView = [CCDirector sharedDirector] .openGLView; // attention 
 [glView.superview insertSubview：_moviePlayer.view atIndex：0]; // attention 
 glView.opaque = NO; // attention 
 glClearColor（0.0f，0.0f，0.0f，0.0f）; // attention 
  

I want the video play in the background, and the text label in the front, run the following code, video is playing, but text label does not show!

-(id) init {
    if(!(self=[super init])) {
        return nil;
    }

    CGSize size = [[CCDirector sharedDirector] winSize];

    // MP4
    NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"test" ofType:@"m4v"]];
    moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
    [moviePlayer respondsToSelector:@selector(setFullscreen:animated:)];
    moviePlayer.controlStyle = MPMovieControlStyleNone;
    moviePlayer.shouldAutoplay = YES;
    moviePlayer.repeatMode = MPMovieRepeatModeOne;
    moviePlayer.view.frame = CGRectMake(0, 0, size.height, size.width);
    [viewController.view  addSubview:moviePlayer.view];
    [viewController.view  sendSubviewToBack:moviePlayer.view];

    // create and initialize a Label
    CCLabelTTF *label = [CCLabelTTF labelWithString:@"Hello World" fontName:@"Marker Felt" fontSize:64];
    label.position =  ccp( size.width /2 , size.height/2 );
    [self addChild: label];

    return self;
}

解决方案

I found the answer:

First in AppDelegate.m replace kEAGLColorFormatRGB565 with kEAGLColorFormatRGBA8, Second, as the following code, the last 4 lines is important:

NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"video" ofType:@"mp4"]];
_moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlayBackDidFinish)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:_moviePlayer];

[_moviePlayer respondsToSelector:@selector(setFullscreen:animated:)];
_moviePlayer.controlStyle = MPMovieControlStyleNone;
_moviePlayer.shouldAutoplay = YES;
_moviePlayer.repeatMode = MPMovieRepeatModeOne;
_moviePlayer.view.frame = CGRectMake(0, 0, 300, 300);

UIView* glView = [CCDirector sharedDirector].openGLView; // attention
[glView.superview insertSubview:_moviePlayer.view atIndex:0]; // attention
glView.opaque = NO; // attention
glClearColor(0.0f, 0.0f, 0.0f, 0.0f); // attention
