一. 播放本地视频
对于IOS平台的视频播放，我们可以借助Cocos2d-iphone 的Extensions：CCVideoPlayer来实现
1.导入支持cocos2d-x的扩展库到项目中（这里可以参考Himi的第六章视频播放小节内容，这里的扩展库是Himi修改好的，我就直接拿来用了！希望没有侵权！）
2.添加MediaPalyer框架到项目中
3.修改ios里AppController.h 和AppController.mm文件
AppController.h
[plain] view
plaincopy
#import "../Classes/CCVideoPlayeriOS/CCVideoPlayer.h"
@class RootViewController;
@interface AppController : NSObject <UIAccelerometerDelegate, UIAlertViewDelegate,
UITextFieldDelegate,UIApplicationDelegate,CCVideoPlayerDelegate>
{
UIWindow *window;
RootViewController *viewController;
}
@property (nonatomic, retain) UIWindow *window;
@property (nonatomic, retain) RootViewController *viewController;
-(void)playVideo;
@end
AppController.mm
添加using namespace cocos2d;
因为playVideo用到了cocos2d-x里的api
CCSizesize = CCDirector::sharedDirector()->getWinSize();
在application函数里添加视频播放监听
[CCVideoPlayer setDelegate :self];
playVideo实现如下：
[plain] view
plaincopy
-(void)playVideo
{
CCSize size = CCDirector::sharedDirector()->getWinSize();
[CCVideoPlayer setScrrenSize:CGSizeMake(size.width-400, size.height-300)];
[CCVideoPlayer setNoSkip:true];
[CCVideoPlayer playMovieWithFile:@"xcm.mp4"];
// 播放网络视频
// [viewController playURLVideo];
}
4.添加混编类IOSPlayVideo
IOSPlayVideo.h
[plain] view
plaincopy
#ifndef __IOSPlayVideo_SCENE_H__
#define __IOSPlayVideo_SCENE_H__
class IOSPlayVideo
{
public:
static void playVideoForIOS();
};
#endif // __IOSPlayVideo_SCENE_H__
IOSPlayVideo.mm
[plain] view
plaincopy
#include "IOSPlayVideo.h"
#include "AppController.h"
void IOSPlayVideo::playVideoForIOS()
{
AppController *app = (AppController*) [[UIApplication sharedApplication] delegate];
[app playVideo];
}
5.添加一个cocos2d-x类 ：Platform
Platform.h
[plain] view
plaincopy
#ifndef __Platform_SCENE_H__
#define __Platform_SCENE_H__
#include "cocos2d.h"
using namespace cocos2d;
class Platform
{
public:
static void playVideo();//用于播放本地视频
static void playURLVideo();//用于播放网络视频
};
#endif // __Platform_SCENE_H__
Platform.mm
[plain] view
plaincopy
#include "Platform.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 Platform::playVideo()
{
#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
//Android播放本地视频
JniMethodInfo minfo;
bool isHave = JniHelper::getMethodInfo(minfo,"org/cocos2dx/playvideo/playvideo","playVedio", "()V");
if (isHave)
{
minfo.env->CallStaticVoidMethod(minfo.classID, minfo.methodID);
}
#elif(CC_TARGET_PLATFORM==CC_PLATFORM_IOS)
//IOS播放本地视频
IOSPlayVideo::playVideoForIOS();
#endif
}
void Platform::playURLVideo()
{
#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
//Android播放网络视频
JniMethodInfo minfo;
bool isHave = JniHelper::getMethodInfo(minfo,"org/cocos2dx/playvideo/playvideo","playURLVideo", "()V");
if (isHave)
{
minfo.env->CallStaticVoidMethod(minfo.classID, minfo.methodID);
}
#elif(CC_TARGET_PLATFORM==CC_PLATFORM_IOS)
//IOS播放网络视频
IOSPlayVideo::playVideoForIOS();
#endif
}
IOS项目里只需在需要的地方调用函数就可以播放视频了！
至于Android就稍微麻烦一点，需要用到Jni 技术, C++调用java
A.修改playvideo.java
修改后如下：
[java] view
plaincopy
package org.cocos2dx.playvideo;
import org.cocos2dx.lib.Cocos2dxActivity;
import org.cocos2dx.lib.Cocos2dxEditText;
import org.cocos2dx.lib.Cocos2dxGLSurfaceView;
import org.cocos2dx.lib.Cocos2dxRenderer;
import android.app.ActivityManager;

import android.content.Intent;
import android.content.pm.ConfigurationInfo;
import android.os.Bundle;
import android.util.Log;
import android.view.ViewGroup;
import android.widget.FrameLayout;
public class playvideo extends Cocos2dxActivity {
//当前类实例
public static playvideo instance;
//用于切换Activity
public static Intent intent;
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
instance =this;
if (detectOpenGLES20()) {
// get the packageName,it's used to set the resource path
String packageName = getApplication().getPackageName();
super.setPackageName(packageName);
// FrameLayout
ViewGroup.LayoutParams framelayout_params =
new ViewGroup.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT,
ViewGroup.LayoutParams.FILL_PARENT);
FrameLayout framelayout = new FrameLayout(this);
framelayout.setLayoutParams(framelayout_params);
// Cocos2dxEditText layout
ViewGroup.LayoutParams edittext_layout_params =
new ViewGroup.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
Cocos2dxEditText edittext = new Cocos2dxEditText(this);
edittext.setLayoutParams(edittext_layout_params);
// ...add to FrameLayout
framelayout.addView(edittext);
// Cocos2dxGLSurfaceView
mGLView = new Cocos2dxGLSurfaceView(this);
// ...add to FrameLayout
framelayout.addView(mGLView);
mGLView.setEGLContextClientVersion(2);
mGLView.setCocos2dxRenderer(new Cocos2dxRenderer());
mGLView.setTextField(edittext);
// Set framelayout as the content view
setContentView(framelayout);
intent = new Intent(playvideo.this, VedioActivity.class);
}
else {
Log.d("activity", "don't support gles2.0");
finish();
}
}
void playVideo()
{
instance.startActivity(intent);
}
@Override
protected void onPause() {
super.onPause();
mGLView.onPause();
}
@Override
protected void onResume() {
super.onResume();
mGLView.onResume();
}
private boolean detectOpenGLES20()
{
ActivityManager am =
(ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
ConfigurationInfo info = am.getDeviceConfigurationInfo();
return (info.reqGlEsVersion >= 0x20000);
}
static {
System.loadLibrary("game");
}
}
添加两个.java文件：VideoView.java和VedioActivity.java

VedioActivity.java
[java] view
plaincopy
package org.cocos2dx.playvideo;
import android.app.Activity;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;
public class VedioActivity extends Activity implements MediaPlayer.OnCompletionListener{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//隐藏标题栏
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
//隐藏状态栏
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
//初始化视频View
VideoView view =new VideoView(this);
//设置显示视频View
setContentView(view);
//注册监听视频
view.setOnCompletionListener(this);
//设置视频文件路径
view.setVideoURI(Uri.parse("android.resource://org.cocos2dx.playvideo/" + R.raw.xcm));
//播放视频
view.start();
}
//当视频播放完后回调此函数
@Override
public void onCompletion(MediaPlayer mp) {
//结束当前Activity
this.finish();
}
}
注：在 res下新建一个名为raw的文件夹，将assets下xcm.mp4拷贝到raw文件夹下，否则 ：raw 和xcm无法识别！！！
二.播放网络视频
IOS项目：
在RootViewController.h里添加playURLVideo函数
并导入头文件#import"MediaPlayer/MediaPlayer.h"
RootViewController.mm实现playURLVideo函数如下：
[plain] view
plaincopy
-(void)playURLVideo
{
NSURL *movieUrl = [NSURL URLWithString:@"http://v.youku.com/player/getRealM3U8/vid/XMzU5NDE3NTYw/type//video.m3u8"];
MPMoviePlayerViewController *player = [[MPMoviePlayerViewController alloc] initWithContentURL:movieUrl];
[self presentMoviePlayerViewControllerAnimated:player];
}
然后修改AppController.mm里的函数
[plain] view
plaincopy
-(void)playVideo
{
// CCSize size = CCDirector::sharedDirector()->getWinSize();
// [CCVideoPlayer setScrrenSize:CGSizeMake(size.width-400, size.height-300)];
// [CCVideoPlayer setNoSkip:true];
// [CCVideoPlayer playMovieWithFile:@"xcm.mp4"];
//播放网络视频
[viewController playURLVideo];
}
Android项目：修改playvideo.java
修改后如下：
[java] view
plaincopy
package org.cocos2dx.playvideo;
import org.cocos2dx.lib.Cocos2dxActivity;
import android.net.Uri;
import android.os.Bundle;
import android.content.Intent;
public class playvideo extends Cocos2dxActivity{
//当前类实例
public static playvideo instance;
//用于切换Activity
public static Intent intent;
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
instance =this;
}
void playURLVideo()
{
Intent intent = new Intent(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);
}
static {
System.loadLibrary("game");
}
}
对于IOS平台的视频播放，我们可以借助Cocos2d-iphone 的Extensions：CCVideoPlayer来实现
1.导入支持cocos2d-x的扩展库到项目中（这里可以参考Himi的第六章视频播放小节内容，这里的扩展库是Himi修改好的，我就直接拿来用了！希望没有侵权！）
2.添加MediaPalyer框架到项目中
3.修改ios里AppController.h 和AppController.mm文件
AppController.h
[plain] view
plaincopy
#import "../Classes/CCVideoPlayeriOS/CCVideoPlayer.h"
@class RootViewController;
@interface AppController : NSObject <UIAccelerometerDelegate, UIAlertViewDelegate,
UITextFieldDelegate,UIApplicationDelegate,CCVideoPlayerDelegate>
{
UIWindow *window;
RootViewController *viewController;
}
@property (nonatomic, retain) UIWindow *window;
@property (nonatomic, retain) RootViewController *viewController;
-(void)playVideo;
@end
AppController.mm
添加using namespace cocos2d;
因为playVideo用到了cocos2d-x里的api
CCSizesize = CCDirector::sharedDirector()->getWinSize();
在application函数里添加视频播放监听
[CCVideoPlayer setDelegate :self];
playVideo实现如下：
[plain] view
plaincopy
-(void)playVideo
{
CCSize size = CCDirector::sharedDirector()->getWinSize();
[CCVideoPlayer setScrrenSize:CGSizeMake(size.width-400, size.height-300)];
[CCVideoPlayer setNoSkip:true];
[CCVideoPlayer playMovieWithFile:@"xcm.mp4"];
// 播放网络视频
// [viewController playURLVideo];
}
4.添加混编类IOSPlayVideo
IOSPlayVideo.h
[plain] view
plaincopy
#ifndef __IOSPlayVideo_SCENE_H__
#define __IOSPlayVideo_SCENE_H__
class IOSPlayVideo
{
public:
static void playVideoForIOS();
};
#endif // __IOSPlayVideo_SCENE_H__
IOSPlayVideo.mm
[plain] view
plaincopy
#include "IOSPlayVideo.h"
#include "AppController.h"
void IOSPlayVideo::playVideoForIOS()
{
AppController *app = (AppController*) [[UIApplication sharedApplication] delegate];
[app playVideo];
}
5.添加一个cocos2d-x类 ：Platform
Platform.h
[plain] view
plaincopy
#ifndef __Platform_SCENE_H__
#define __Platform_SCENE_H__
#include "cocos2d.h"
using namespace cocos2d;
class Platform
{
public:
static void playVideo();//用于播放本地视频
static void playURLVideo();//用于播放网络视频
};
#endif // __Platform_SCENE_H__
Platform.mm
[plain] view
plaincopy
#include "Platform.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 Platform::playVideo()
{
#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
//Android播放本地视频
JniMethodInfo minfo;
bool isHave = JniHelper::getMethodInfo(minfo,"org/cocos2dx/playvideo/playvideo","playVedio", "()V");
if (isHave)
{
minfo.env->CallStaticVoidMethod(minfo.classID, minfo.methodID);
}
#elif(CC_TARGET_PLATFORM==CC_PLATFORM_IOS)
//IOS播放本地视频
IOSPlayVideo::playVideoForIOS();
#endif
}
void Platform::playURLVideo()
{
#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
//Android播放网络视频
JniMethodInfo minfo;
bool isHave = JniHelper::getMethodInfo(minfo,"org/cocos2dx/playvideo/playvideo","playURLVideo", "()V");
if (isHave)
{
minfo.env->CallStaticVoidMethod(minfo.classID, minfo.methodID);
}
#elif(CC_TARGET_PLATFORM==CC_PLATFORM_IOS)
//IOS播放网络视频
IOSPlayVideo::playVideoForIOS();
#endif
}
IOS项目里只需在需要的地方调用函数就可以播放视频了！
至于Android就稍微麻烦一点，需要用到Jni 技术, C++调用java
A.修改playvideo.java
修改后如下：

// Set framelayout as the content view
setContentView(framelayout);
intent = new Intent(playvideo.this, VedioActivity.class);
}
else {
Log.d("activity", "don't support gles2.0");
finish();
}
}
void playVideo()
{
instance.startActivity(intent);
}
@Override
protected void onPause() {
super.onPause();
mGLView.onPause();
}
@Override

super.onResume();
mGLView.onResume();
}
private boolean detectOpenGLES20()
{

VedioActivity.java
[java] view

import android.view.Window;
import android.view.WindowManager;
public class VedioActivity extends Activity implements MediaPlayer.OnCompletionListener{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//隐藏标题栏
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
//隐藏状态栏
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
//初始化视频View

//设置视频文件路径

//播放视频
view.start();
}
//当视频播放完后回调此函数
@Override
public void onCompletion(MediaPlayer mp) {
//结束当前Activity
this.finish();
}
}
注：在 res下新建一个名为raw的文件夹，将assets下xcm.mp4拷贝到raw文件夹下，否则 ：raw 和xcm无法识别！！！
二.播放网络视频
IOS项目：
在RootViewController.h里添加playURLVideo函数
并导入头文件#import"MediaPlayer/MediaPlayer.h"
RootViewController.mm实现playURLVideo函数如下：
[plain] view
plaincopy
-(void)playURLVideo
{
NSURL *movieUrl = [NSURL URLWithString:@"http://v.youku.com/player/getRealM3U8/vid/XMzU5NDE3NTYw/type//video.m3u8"];
MPMoviePlayerViewController *player = [[MPMoviePlayerViewController alloc] initWithContentURL:movieUrl];
[self presentMoviePlayerViewControllerAnimated:player];
}
然后修改AppController.mm里的函数
[plain] view
plaincopy
-(void)playVideo
{
// CCSize size = CCDirector::sharedDirector()->getWinSize();
// [CCVideoPlayer setScrrenSize:CGSizeMake(size.width-400, size.height-300)];
// [CCVideoPlayer setNoSkip:true];
// [CCVideoPlayer playMovieWithFile:@"xcm.mp4"];
//播放网络视频
[viewController playURLVideo];
}
Android项目：修改playvideo.java
修改后如下：
[java] view
plaincopy
package org.cocos2dx.playvideo;
import org.cocos2dx.lib.Cocos2dxActivity;
import android.net.Uri;
import android.os.Bundle;
import android.content.Intent;
public class playvideo extends Cocos2dxActivity{
//当前类实例
public static playvideo instance;
//用于切换Activity
public static Intent intent;
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
instance =this;
}
void playURLVideo()
{
Intent intent = new Intent(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);
}
static {
System.loadLibrary("game");
}
}
