Cocos2d-x v2.2.3 IOS，Android “一键式”播放视频

参考文献：http://blog.csdn.net/candyforever/article/details/8905852

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

#ifndef __Platform_H_H__  
#define __Platform_H_H__  
#include "cocos2d.h"  
using namespace cocos2d;  
class VideoPlatform   
{  
 public:  
    //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)  
    static void playVideo(const char * filename,CCLayer *layer =NULL);  
};  
  
#endif // __Platform_H_H__  

VideoPlatform.cpp

#include "VideoPlatform.h"  
#include "../../cocos2dx/platform/CCPlatformConfig.h"  
#if (CC_TARGET_PLATFORM==CC_PLATFORM_ANDROID)  
#include <jni.h>  
#include "../../cocos2dx/platform/android/jni/JniHelper.h"  
#include <android/log.h>  
#elif(CC_TARGET_PLATFORM==CC_PLATFORM_IOS)  
#include "IOSPlayVideo.h"  
#endif  
  
void VideoPlatform::playVideo(const char * filename,CCLayer *layer)  
{  
#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)  
    //Android视频播放代码  
    JniMethodInfo minfo;  
    bool isHave = JniHelper::getMethodInfo(minfo,"org/cocos2dx/video/video","playVideo","()V");  
    if (isHave) {  
        minfo.env->CallStaticVoidMethod(minfo.classID,minfo.methodID);  
    }  
#elif(CC_TARGET_PLATFORM==CC_PLATFORM_IOS)  
    //iOS视频播放代码  
    IOSPlayVideo::playVideoForIOS(filename,layer);  
#endif  
}  

2) IOSPlayVideo是IOS平台播放视频的接口

IOSPlayVideo.h

#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

#import "IOSVideoController.h"  
#import "AppController.h"  
@implementation IOSVideoController  
  
//播放网络视频  
-(void)playUrlVideo  
{  
}  
-(void)playVideo:(NSString *)filename :(CCLayer *)targetLayer  
{  
    TargetLayer =targetLayer;  
    //跳转Layer非空  
    if (targetLayer) {  
        TargetLayer->retain();  
    }  
  
    SimpleAudioEngine::sharedEngine()->pauseBackgroundMusic();  
    SimpleAudioEngine::sharedEngine()->pauseAllEffects();  
  
    NSString *myFilePath = [[NSBundle mainBundle] pathForResource:filename ofType:nil inDirectory:nil];  
    NSURL *url = [NSURL fileURLWithPath:myFilePath];  
      
    movePlayer=[[MPMoviePlayerController alloc] initWithContentURL:url];  
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(movieFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:movePlayer];  
      
    if([movePlayer respondsToSelector:@selector(setFullscreen:animated:)])  
    {  
        movePlayer.shouldAutoplay=YES;  
          
        CCSize winSize=CCDirector::sharedDirector()->getWinSize();  
        CCLog("winSize.width====%f    winSize.height====%f",winSize.width,winSize.height);  
        //         这里iPad2和ipad3 视频位置调整是正确的，Iphone 可能需要细微调整  
          
        if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)  
        {  
            movePlayer.view.frame=CGRectMake(-80,80,480,320);  
        }  
        else if([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)  
        {  
            movePlayer.view.frame=CGRectMake(-128,128,winSize.height);  
        }  
        else  
        {  
            movePlayer.view.frame=CGRectMake(-80,320);  
              
        }  
          
        //        强制横屏  
        CGAffineTransform landscapeTransform;  
        UIDevice *device = [UIDevice currentDevice] ;  
        if (device.orientation==UIDeviceOrientationLandscapeLeft)  
        {  
            landscapeTransform = CGAffineTransformMakeRotation(M_PI / 2);  
        }  
        else  
        {  
            landscapeTransform = CGAffineTransformMakeRotation(-M_PI / 2);  
        }  
        movePlayer.view.transform = landscapeTransform;  
          
        // 新建一个window，添加视频这个UIView  
        window = [[UIWindow alloc] initWithFrame: [[UIScreen mainScreen] bounds]];  
          
        [window addSubview:movePlayer.view];  
        [window makeKeyAndVisible];  
//  在视频上方添加“跳过”按钮        
        CGRect frame = CGRectMake(768-100,100,50);  
        UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];  
        button.frame = frame;  
        [button setTitle:@"跳过" forState: UIControlStateNormal];  
          
        button.transform =landscapeTransform;  
        button.backgroundColor = [UIColor clearColor];  
        button.tag = 2000;  
        [button addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];  
        [window addSubview:button];  
          
  
        //  设置是否带控制条  
        movePlayer.controlStyle = MPMovieControlStyleNone;  
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(exitFullScreen:) name:MPMoviePlayerDidExitFullscreenNotification object:nil];  
          
    }  
    else  
    {  
        movePlayer.controlStyle=MPMovieControlModeHidden;  
    }  
      
    [self playMovie];  
  
  
}  
//跳过视频  
-(IBAction) buttonClicked:(id)sender {  
    [movePlayer stop];  
  
    [movePlayer.view removeFromSuperview];  
    [movePlayer release];  
    [window release];  
    SimpleAudioEngine::sharedEngine()->resumeBackgroundMusic();  
    SimpleAudioEngine::sharedEngine()->resumeAllEffects();  
      
    if (!TargetLayer) {  
        return;  
    }  
    TargetLayer->removeAllChildrenWithCleanup(true);  
    TargetLayer->removeFromParent();  
  
    CCScene * scene =CCScene::create();  
    scene->addChild(TargetLayer,10);  
    CCDirector::sharedDirector()->replaceScene(scene);  
      
      
}  
//播放开始  
-(void) playMovie  
{  
    MPMoviePlaybackState state=movePlayer.playbackState;  
    if(state==MPMoviePlaybackStatePlaying)  
    {  
        NSLog(@"Movie is already playing.");  
        return;  
    }  
    [movePlayer play];  
}  
//退出全屏  
-(void)exitFullScreen:(NSNotification *)notification{  
    CCLOG("exitFullScreen");  
    movePlayer.controlStyle=MPMovieControlStyleDefault;  
    [movePlayer.view removeFromSuperview];  
}  
//视频播放结束  
- (void) movieFinished:(NSNotificationCenter *)notification{  
//    CCLOG("moviePlaybackFinished");  
    //视频播放完毕  
    
    movePlayer.controlStyle=MPMovieControlStyleDefault;  
    MPMoviePlaybackState state=movePlayer.playbackState;  
    if(state==MPMoviePlaybackStateStopped){  
        NSLog(@"Movie is already stopped.");  
        return;  
    }  
    [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:movePlayer];  
    if([movePlayer respondsToSelector:@selector(setFullscreen:animated:)])  
    {  
  
        [movePlayer.view removeFromSuperview];  
        [window release];  
          
        SimpleAudioEngine::sharedEngine()->resumeBackgroundMusic();  
        SimpleAudioEngine::sharedEngine()->resumeAllEffects();  
          
        if (!TargetLayer) {  
            return;  
        }  
        TargetLayer->removeAllChildrenWithCleanup(true);  
        TargetLayer->removeFromParent();  
        CCScene * scene =CCScene::create();  
        scene->addChild(TargetLayer,10);  
        CCDirector::sharedDirector()->replaceScene(scene);  
  
    }  
      
}  
  
- (void)dealloc {  
    [super dealloc];  
    if (TargetLayer) {  
            TargetLayer->release();  
    }  
  
}  
@end  

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];

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

package com.hj.test;
import android.app.Activity;  
import android.content.pm.ActivityInfo;  
import android.media.MediaPlayer;  
import android.net.Uri;  
import android.os.Bundle;  
import android.view.Window;  
import android.view.WindowManager;  
import android.widget.MediaController;  
import android.widget.VideoView;  

public class VideoActivity extends Activity {    
    @Override    
    protected void onCreate(Bundle savedInstanceState) {     
        super.onCreate(savedInstanceState);    
        requestWindowFeature(Window.FEATURE_NO_TITLE);  
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);   
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);  
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);//强制为横屏  
        setContentView(R.layout.videoview);  
       
       final VideoView videoView = (VideoView)findViewById(R.id.VideoView01);   
        videoView.setVideoURI(Uri.parse("android.resource://" + getPackageName() + "/" +R.raw.cocosvideo));   
        videoView.start();   
//        视频播控制条设置  
          MediaController controller = new MediaController(VideoActivity.this);  
          videoView.setMediaController(controller);  
//        播放完成监听  
          videoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener()  
           {  
             @Override  
             public void onCompletion(MediaPlayer mp)  
             {  
               //播放结束后的动作,返回点击播放视频的那个页面  
                finish();  
             }  
            });         
    }    
}   

2) 修改AndroidManifest.xml，添加一个Activity

<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>

<?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>

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

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. }

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. }
