本篇文章会给大家介绍在对IOS 和Android开发时，是如何实现播放视频这个功能的，下面就分别给大家介绍下。

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  copy

#ifndef __Platform_H_H__

#define __Platform_H_H__

#include "cocos2d.h"

usingnamespacecocos2d;

classVideoPlatform

{

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)

staticvoidplayVideo(constchar* filename,CCLayer *layer =NULL);

};

#endif // __Platform_H_H__

VideoPlatform.cppcopy

#include "VideoPlatform.h"

#include "../../cocos2dx/platform/CCPlatformConfig.h"

#if (CC_TARGET_PLATFORM==CC_PLATFORM_ANDROID)

#include

#include "../../cocos2dx/platform/android/jni/JniHelper.h"

#include

#elif(CC_TARGET_PLATFORM==CC_PLATFORM_IOS)

#include "IOSPlayVideo.h"

#endif

voidVideoPlatform::playVideo(constchar* filename,CCLayer *layer)

{

#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)

//Android视频播放代码

JniMethodInfo minfo;

boolisHave = 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.hcopy

#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

#include "IOSPlayVideo.h"

#include "IOSVideoController.h"

voidIOSPlayVideo::playVideoForIOS(constchar* filename,CCLayer *layer)

{

//   char * 转化为 NSString

NSString *audioname=[NSString stringWithUTF8String:filename];

IOSVideoController *app = [[IOSVideoController alloc] init];

[app playVideo:audioname :layer];

}

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

IOSVideoController.hcopy

#import "MediaPlayer/MediaPlayer.h"

#import "cocos2d.h"

#include "SimpleAudioEngine.h"

usingnamespacecocos2d;

usingnamespaceCocosDenshion;

@interface IOSVideoController :MPMoviePlayerViewController

{

MPMoviePlayerController *movePlayer;

UIWindow *window;

CCLayer *TargetLayer;

}

//播放网络视频

-(void)playUrlVideo;

//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

-(void)playVideo:(NSString *)filename :(CCLayer *)targetLayer;

@end

IOSVideoController.mmcopy

#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);

}

elseif([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)

{

movePlayer.view.frame=CGRectMake(-128, 128, winSize.width, winSize.height);

}

else

{

movePlayer.view.frame=CGRectMake(-80,80, 480, 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, 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

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

NSURL *url = [NSURL URLWithString:@"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

packageorg.cocos2dx.video;

importandroid.app.Activity;

importandroid.content.pm.ActivityInfo;

importandroid.media.MediaPlayer;

importandroid.net.Uri;

importandroid.os.Bundle;

importandroid.view.Window;

importandroid.view.WindowManager;

importandroid.widget.MediaController;

importandroid.widget.VideoView;

publicclassVideoActivityextendsActivity {

@Override

protectedvoidonCreate(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);

finalVideoView videoView = (VideoView)findViewById(R.id.VideoView01);

videoView.setVideoURI(Uri.parse("android.resource://"getPackageName()"/"R.raw.theme));

videoView.start();

//        视频播控制条设置

MediaController controller = newMediaController(VideoActivity.this);

videoView.setMediaController(controller);

//        播放完成监听

videoView.setOnCompletionListener(newMediaPlayer.OnCompletionListener()

{

@Override

publicvoidonCompletion(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

android:label="@string/app_name"

android:screenOrientation="landscape"

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

android:configChanges="orientation">

3) 在res /layout添加一个 videoview.xmlcopy

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:gravity="center"

tools:context=".VideoActivity">

android:id="@ id/VideoView01"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:layout_alignParentLeft="true"

android:layout_alignParentRight="true"

android:layout_alignParentTop="true"

android:orientation="horizontal"

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"/>

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)copy

packageorg.cocos2dx.video;

importorg.cocos2dx.lib.Cocos2dxActivity;

importorg.cocos2dx.lib.Cocos2dxGLSurfaceView;

importandroid.content.Intent;

importandroid.os.Bundle;

publicclassvideoextendsCocos2dxActivity{

publicstaticvideo instance;

publicstaticIntent intent;

protectedvoidonCreate(Bundle savedInstanceState){

super.onCreate(savedInstanceState);

instance =this;

intent = newIntent(video.this, VideoActivity.class);

}

voidplayVideo()

{

instance.startActivity(intent);

}

publicCocos2dxGLSurfaceView onCreateView() {

Cocos2dxGLSurfaceView glSurfaceView = newCocos2dxGLSurfaceView(this);

// video should create stencil buffer

glSurfaceView.setEGLConfigChooser(5,6,5,0,16,8);

returnglSurfaceView;

}

static{

System.loadLibrary("cocos2dcpp");

}

}

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()

{

Intent intent = newIntent(Intent.ACTION_VIEW);

String type = "video/* ";

Uri uri = Uri.parse("http://forum.ea3w.com/coll_ea3w/attach/2008_10/12237832415.3gp");

intent.setDataAndType(uri, type);

instance.startActivity(intent);

}
