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

[cpp]view plaincopy 
   
 #ifndef__IOSPlayVideo_H_H__
 #define__IOSPlayVideo_H_H__
 
 #include"cocos2d.h"
 usingnamespacecocos2d;
 classIOSPlayVideo
 {
public:
staticvoidplayVideoForIOS(constchar*filename,CCLayer*layer);
 
 };
 #endif//__IOSPlayVideo_H_H__

IOSPlayVideo.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

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(); } }); } }
