下面简单实现Cocos2d-x一个视频播放的模块，需要播放视频时,不用到处乱改了，一句代码搞定！

一. IOS播放本地视频

对于IOS平台的视频播放，这里直接使用MediaPlayer.framework来播放视频

注意：MediaPlayer.framework播放视频格式有限，可能需要转换为指定的视频格式才能播放！

1.添加MediaPalyer框架到项目中

2.简单写三个类

VideoPlatform,IOSPlayVideo,IOSVideoController

1）VideoPlatform 这个类用来判断播放视频的平台，从而调用各自平台的视频播放接口

VideoPlatform.h 

  1. #ifndef __Platform_H_H__  
  2. #define __Platform_H_H__  
  3. #include "cocos2d.h"  
  4. using namespace cocos2d;  
  5. class VideoPlatform   
  6. {  
  7.  public:  
  8.     //在当前的layer上播放视频，视频完毕或者点击跳过视频会跳转到指定的layer上(默认为空，也就是停留在当前layer上)  
  9.     static void playVideo(const char * filename,CCLayer *layer =NULL);  
  10. };  
  11.   
  12. #endif // __Platform_H_H__


VideoPlatform.cpp

  1. #include "VideoPlatform.h"  
  2. #include "../../cocos2dx/platform/CCPlatformConfig.h"  
  3. #if (CC_TARGET_PLATFORM==CC_PLATFORM_ANDROID)  
  4. #include <jni.h>  
  5. #include "../../cocos2dx/platform/android/jni/JniHelper.h"  
  6. #include <android/log.h>  
  7. #elif(CC_TARGET_PLATFORM==CC_PLATFORM_IOS)  
  8. #include "IOSPlayVideo.h"  
  9. #endif  
  10.   
  11. void VideoPlatform::playVideo(const char * filename,CCLayer *layer)  
  12. {  
  13. #if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)  
  14.     //Android视频播放代码  
  15.     JniMethodInfo minfo;  
  16.     bool isHave = JniHelper::getMethodInfo(minfo,"org/cocos2dx/video/video","playVideo","()V");  
  17.     if (isHave) {  
  18.         minfo.env->CallStaticVoidMethod(minfo.classID,minfo.methodID);  
  19.     }  
  20. #elif(CC_TARGET_PLATFORM==CC_PLATFORM_IOS)  
  21.     //iOS视频播放代码  
  22.     IOSPlayVideo::playVideoForIOS(filename,layer);  
  23. #endif  
  24. }


2) IOSPlayVideo是IOS平台播放视频的接口

IOSPlayVideo.h

[cpp] view plain copy
  1. #ifndef__IOSPlayVideo_H_H__
  2. #define__IOSPlayVideo_H_H__
  4. #include"cocos2d.h"
  5. usingnamespacecocos2d;
  6. classIOSPlayVideo
  7. {
  8. public:
  9. staticvoidplayVideoForIOS(constchar*filename,CCLayer*layer);
  11. };
  12. #endif//__IOSPlayVideo_H_H__

IOSPlayVideo.mm

    #include"IOSPlayVideo.h"
  1. #include"IOSVideoController.h"
  2. voidIOSPlayVideo::playVideoForIOS( //char*转化为NSString
  3. NSString*audioname=[NSStringstringWithUTF8String:filename];
  4. IOSVideoController*app=[[IOSVideoControlleralloc]init];
  5. [appplayVideo:audioname:layer];
  6. }

3)最后IOSVideoController这个类就是ios播放视频的具体实现了

IOSVideoController.h

    #import"MediaPlayer/MediaPlayer.h"
  1. #import"cocos2d.h"
  2. #include"SimpleAudioEngine.h"
  3. namespacecocos2d;
  4. namespaceCocosDenshion;
  5. @interfaceIOSVideoController:MPMoviePlayerViewController
  6. {
  7. MPMoviePlayerController*movePlayer;
  8. UIWindow*window;
  9. CCLayer*TargetLayer;
  10. }
  11. //播放网络视频
  12. -(void)playUrlVideo;
  13. //在当前场景上播放视频，播完或者点击跳过视频到指定的场景
  14. -(void)playVideo:(NSString*)filename:(CCLayer*)targetLayer;
  15. @end

IOSVideoController.mm

  1. #import "IOSVideoController.h"  
  2. #import "AppController.h"  
  3. @implementation IOSVideoController  
  4.   
  5. //播放网络视频  
  6. -(void)playUrlVideo  
  7. {  
  8. }  
  9. -(void)playVideo:(NSString *)filename :(CCLayer *)targetLayer  
  10. {  
  11.     TargetLayer =targetLayer;  
  12.     //跳转Layer非空  
  13.     if (targetLayer) {  
  14.         TargetLayer->retain();  
  15.     }  
  16.   
  17.     SimpleAudioEngine::sharedEngine()->pauseBackgroundMusic();  
  18.     SimpleAudioEngine::sharedEngine()->pauseAllEffects();  
  19.   
  20.     NSString *myFilePath = [[NSBundle mainBundle] pathForResource:filename ofType:nil inDirectory:nil];  
  21.     NSURL *url = [NSURL fileURLWithPath:myFilePath];  
  22.       
  23.     movePlayer=[[MPMoviePlayerController alloc] initWithContentURL:url];  
  24.     [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(movieFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:movePlayer];  
  25.       
  26.     if([movePlayer respondsToSelector:@selector(setFullscreen:animated:)])  
  27.     {  
  28.         movePlayer.shouldAutoplay=YES;  
  29.           
  30.         CCSize winSize=CCDirector::sharedDirector()->getWinSize();  
  31.         CCLog("winSize.width====%f    winSize.height====%f",winSize.width,winSize.height);  
  32.         //         这里iPad2和ipad3 视频位置调整是正确的，Iphone 可能需要细微调整  
  33.           
  34.         if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)  
  35.         {  
  36.             movePlayer.view.frame=CGRectMake(-80,80,480,320);  
  37.         }  
  38.         else if([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)  
  39.         {  
  40.             movePlayer.view.frame=CGRectMake(-128,128,winSize.height);  
  41.         }  
  42.         else  
  43.         {  
  44.             movePlayer.view.frame=CGRectMake(-80,320);  
  45.               
  46.         }  
  47.           
  48.         //        强制横屏  
  49.         CGAffineTransform landscapeTransform;  
  50.         UIDevice *device = [UIDevice currentDevice] ;  
  51.         if (device.orientation==UIDeviceOrientationLandscapeLeft)  
  52.         {  
  53.             landscapeTransform = CGAffineTransformMakeRotation(M_PI / 2);  
  54.         }  
  55.         else  
  56.         {  
  57.             landscapeTransform = CGAffineTransformMakeRotation(-M_PI / 2);  
  58.         }  
  59.         movePlayer.view.transform = landscapeTransform;  
  60.           
  61.         // 新建一个window，添加视频这个UIView  
  62.         window = [[UIWindow alloc] initWithFrame: [[UIScreen mainScreen] bounds]];  
  63.           
  64.         [window addSubview:movePlayer.view];  
  65.         [window makeKeyAndVisible];  
  66. //  在视频上方添加“跳过”按钮        
  67.         CGRect frame = CGRectMake(768-100,100,50);  
  68.         UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];  
  69.         button.frame = frame;  
  70.         [button setTitle:@"跳过" forState: UIControlStateNormal];  
  71.           
  72.         button.transform =landscapeTransform;  
  73.         button.backgroundColor = [UIColor clearColor];  
  74.         button.tag = 2000;  
  75.         [button addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];  
  76.         [window addSubview:button];  
  77.           
  78.   
  79.         //  设置是否带控制条  
  80.         movePlayer.controlStyle = MPMovieControlStyleNone;  
  81.         [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(exitFullScreen:) name:MPMoviePlayerDidExitFullscreenNotification object:nil];  
  82.           
  83.     }  
  84.     else  
  85.     {  
  86.         movePlayer.controlStyle=MPMovieControlModeHidden;  
  87.     }  
  88.       
  89.     [self playMovie];  
  90.   
  91.   
  92. }  
  93. //跳过视频  
  94. -(IBAction) buttonClicked:(id)sender {  
  95.     [movePlayer stop];  
  96.   
  97.     [movePlayer.view removeFromSuperview];  
  98.     [movePlayer release];  
  99.     [window release];  
  100.     SimpleAudioEngine::sharedEngine()->resumeBackgroundMusic();  
  101.     SimpleAudioEngine::sharedEngine()->resumeAllEffects();  
  102.

  104.         return;  
  105.     }  
  106.     TargetLayer->removeAllChildrenWithCleanup(true);  
  107.     TargetLayer->removeFromParent();  
  108.   
  109.     CCScene * scene =CCScene::create();  
  110.     scene->addChild(TargetLayer,10);  
  111.     CCDirector::sharedDirector()->replaceScene(scene);  
  112.       
  113.       
  114. }  
  115. //播放开始  
  116. -(void) playMovie  
  117. {  
  118.     MPMoviePlaybackState state=movePlayer.playbackState;  
  119.     if(state==MPMoviePlaybackStatePlaying)  
  120.     {  
  121.         NSLog(@"Movie is already playing.");  
  122.         return;  
  123.     }  
  124.     [movePlayer play];  
  125. }  
  126. //退出全屏  
  127. -(void)exitFullScreen:(NSNotification *)notification{  
  128.     CCLOG("exitFullScreen");  
  129.     movePlayer.controlStyle=MPMovieControlStyleDefault;  
  130.     [movePlayer.view removeFromSuperview];  
  131. }  
  132. //视频播放结束  
  133. - (void) movieFinished:(NSNotificationCenter *)notification{  
  134. //    CCLOG("moviePlaybackFinished");  
  135.     //视频播放完毕  
  136.     
  137.     movePlayer.controlStyle=MPMovieControlStyleDefault;  
  138.     MPMoviePlaybackState state=movePlayer.playbackState;  
  139.     if(state==MPMoviePlaybackStateStopped){  
  140.         NSLog(@"Movie is already stopped.");  
  141.         return;  
  142.     }  
  143.     [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:movePlayer];  
  144.     if([movePlayer respondsToSelector:@selector(setFullscreen:animated:)])  
  145.     {  
  146.   
  147.         [movePlayer.view removeFromSuperview];  
  148.         [window release];

  161.   
  162.     }  
  163.       
  164. }  
  165.   
  166. - (void)dealloc {  
  167.     [super dealloc];  
  168.     if (TargetLayer) {  
  169.             TargetLayer->release();  
  170.     }  
  171.   
  172. }

IOS项目里只需在需要的地方调用接口

//只在当前layer上播放视频，播完不跳转就调这个

VideoPlatform::playVideo("test.mp4");

//当前layer上播放视频，播完跳转到指定layer就调这个

VideoPlatform::playVideo("test.mp4",TestLayer::create());

就可以播放视频了！有没有发觉世界瞬间变得美好了一点呢？

二.IOS播放网络视频

只需将

    NSURL*url=[NSURLfileURLWithPath:myFilePath];
类似改为：

    NSURL*url=[NSURLURLWithString:@"http://127.0.0.1/test.mp4"];

（后面填写视频地址就OK！）

三.Android 播放本地视频

至于Android就稍微麻烦一点，需要用到Jni 技术,C++调用java

1) 添加一个VideoActivity

  1. package com.hj.test;
  2. import android.app.Activity;  
  3. import android.content.pm.ActivityInfo;  
  4. import android.media.MediaPlayer;  
  5. import android.net.Uri;  
  6. import android.os.Bundle;  
  7. import android.view.Window;  
  8. import android.view.WindowManager;  
  9. import android.widget.MediaController;  
  10. import android.widget.VideoView;  
  11.  
  12. public class VideoActivity extends Activity {    
  13.     @Override    
  14.     protected void onCreate(Bundle savedInstanceState) {     
  15.         super.onCreate(savedInstanceState);    
  16.         requestWindowFeature(Window.FEATURE_NO_TITLE);  
  17.         getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);   
  18.         getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);  
  19.         setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);//强制为横屏  
  20.         setContentView(R.layout.videoview);  
  21.        
  22.        final VideoView videoView = (VideoView)findViewById(R.id.VideoView01);   
  23.         videoView.setVideoURI(Uri.parse("android.resource://" + getPackageName() + "/" +R.raw.cocosvideo));   
  24.         videoView.start();   
  25. //        视频播控制条设置  
  26.           MediaController controller = new MediaController(VideoActivity.this);  
  27.           videoView.setMediaController(controller);  
  28. //        播放完成监听  
  29.           videoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener()  
  30.            {  
  31.              @Override  
  32.              public void onCompletion(MediaPlayer mp)  
  33.              {  
  34.                //播放结束后的动作,返回点击播放视频的那个页面  
  35.                 finish();  
  36.              }  
  37.             });         
  38.     }    
  39. }

2) 修改AndroidManifest.xml，添加一个Activity

[html]
    <activityandroid:name="VideoActivity"
  1. android:label="@string/app_name"
  2. android:screenOrientation="landscape"
  3. android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
  4. android:configChanges="orientation">
  5. intent-filter>
  6. actionandroid:name="android.intent.action.MAIN"/>
  7. categoryandroid:name="android.intent.category.DEFAULT"/>
  8. </activity>


3) 在res /layout添加一个 videoview.xml

    <?xmlversion="1.0"encoding="utf-8"?>
  1. RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"
  2. xmlns:tools="http://schemas.android.com/tools"
  3. android:layout_width="match_parent"
  4. android:layout_height="match_parent"
  5. android:gravity="center"
  6. tools:context=".VideoActivity"VideoView
  7. android:id="@+id/VideoView01"
  8. android:layout_width="fill_parent"
  9. android:layout_height="fill_parent"
  10. android:layout_alignParentLeft="true"
  11. android:layout_alignParentRight="true"
  12. android:layout_alignParentTop="true"
  13. android:orientation="horizontal"
  14. android:theme="@android:style/Theme.NoTitleBar.Fullscreen"RelativeLayout>


4)在res 下添加一个raw文件夹，里面放你要播放的视频，例如：theme.mp4，这里我的视频文件名为theme


5)修改video.java (我的Android 项目包名为 org.cocos2dx.video)

[java]
    packageorg.cocos2dx.video;
  1. importorg.cocos2dx.lib.Cocos2dxActivity;
  2. importorg.cocos2dx.lib.Cocos2dxGLSurfaceView;
  3. importandroid.content.Intent;
  4. importandroid.os.Bundle;
  5. publicclassvideoextendsCocos2dxActivity{
  6. staticvideoinstance;
  7. staticIntentintent;
  8. protectedvoidonCreate(BundlesavedInstanceState){
  9. super.onCreate(savedInstanceState);
  10. instance=this;
  11. intent=newIntent(video.this,VideoActivity.class);
  12. }
  13. voidplayVideo()
  14. instance.startActivity(intent);
  15. publicCocos2dxGLSurfaceViewonCreateView(){
  16. Cocos2dxGLSurfaceViewglSurfaceView=newCocos2dxGLSurfaceView(this);
  17. //videoshouldcreatestencilbuffer
  18. glSurfaceView.setEGLConfigChooser(5,6,0); background-color:inherit">0,0); background-color:inherit">16,0); background-color:inherit">8);
  19. returnglSurfaceView;
  20. static{
  21. System.loadLibrary("cocos2dcpp");
  22. }


至此 Android播放本地视频就OK了！

四.Android 播放网络视频


新添加一个如下方法即可(同样也可以使用JNI C++调Java)

    voidplayURLVideo()
  1. Intentintent=newIntent(Intent.ACTION_VIEW);
  2. Stringtype="video/*";
  3. Uriuri=Uri.parse("http://forum.ea3w.com/coll_ea3w/attach/2008_10/12237832415.3gp");
  4. intent.setDataAndType(uri,type);
  5. instance.startActivity(intent);
  6. }
