17.音乐播放器相关的开源介绍

1.频谱波形图，频谱柱状图，通知栏控制音乐，频谱效果................

 

18.网络音乐播放器,网络收音机

 1.网络音乐播放器

public class MainActivity extends Activity implements OnPreparedListener {private MediaPlayer mMediaPlayer;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);}public void click(View v) {try {if (mMediaPlayer == null) {mMediaPlayer = new MediaPlayer();}mMediaPlayer.reset();//mMediaPlayer.setDataSource("http://192.168.1.100:8080/xpg.mp3");mMediaPlayer.setDataSource("mms://mediasrv2.iptv.xmg.com.cn/yinyue");mMediaPlayer.prepareAsync();//网络音乐.应该异步准备mMediaPlayer.setOnPreparedListener(this);} catch (IllegalArgumentException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();}}@Overridepublic void onPrepared(MediaPlayer mp) {//如果使用prepareAsync,应该把start()方法放到这个地方Toast.makeText(getApplicationContext(), "准备好了", 0).show();mMediaPlayer.start();}@Overrideprotected void onDestroy() {if (mMediaPlayer != null) {mMediaPlayer.release();mMediaPlayer = null;}super.onDestroy();}}

2.收音机

(1)FM:调频收音机-->频道-->频段
(2)网络收音机-->频道-->url
(3)使用的是mms串流媒体协议,android sdk不支持
(4)开源->FFMpeg支持-->开发周期长,开发难度大
(5)开放平台(第三方)-->api-->开发者

 

 

19.vitamio介绍

1.博客介绍：http://www.cnblogs.com/over140/archive/2012/04/26/2471060.html

   官网：http://www.yixia.com/

2.支持主流的视音频格式：mp3/mp4/mkv/avi/3gp/rmvb/mov/flv等

3. 支持功能

　(1)当然最重要的是播放功能，含播放控制（播放、暂停，声音、亮度调整等）

　(2)可以扫描SDcard，用列表展现出来，可以搜索

　(3)可以播放网络视音频（http、rtsp、mms）

4.Vitamio是一个支持所有Android设备的多媒体框架。Vitamio与Android默认的MediaPlayer工作方式相似，但包含更加强大的功能！（注意：Vitamio商业化后个人免费、公司收费）

21.vitamio的videoView集成

1.下载lib包.demo:` https://github.com/yixia/VitamioBundle

2.新建工程,引入lib包

3. 是否修改androidmanifest.xml 
 (1). 权限

   <uses-permission android:name="android.permission.INTERNET" />
   
 (2). 添加activity

   <!-- vitamio add -->
          <activity
            android:name="io.vov.vitamio.activity.InitActivity"
            android:configChanges="orientation|screenSize|smallestScreenSize|keyboard|keyboardHidden|navigation"
            android:launchMode="singleTop"
            android:theme="@android:style/Theme.NoTitleBar"
            android:windowSoftInputMode="stateAlwaysHidden" />

4.代码的集成

(1)布局

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context=".MainActivity" >    <io.vov.vitamio.widget.VideoView        android:id="@+id/vitamio_vv"        android:layout_width="match_parent"        android:layout_height="match_parent" /></RelativeLayout>

(2)MainActivity.java

public class MainActivity extends Activity implements OnPreparedListener, OnErrorListener, OnCompletionListener {private VideoView mVitamio_vv;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);//使用vitamio需要初始化引擎,引擎的检查/**---------------需要注意 begin---------------**/if (!LibsChecker.checkVitamioLibs(this))return;/**---------------需要注意 end---------------**/mVitamio_vv = (VideoView) findViewById(R.id.vitamio_vv);/**---------------设置监听---------------**/mVitamio_vv.setOnPreparedListener(this);mVitamio_vv.setOnErrorListener(this);mVitamio_vv.setOnCompletionListener(this);//设置路径//本地视频//网络视频//流媒体mVitamio_vv.setVideoPath("storage/emulated/0/Download/5.mkv");//设置控制条mVitamio_vv.setMediaController(new MediaController(this));//开始播放mVitamio_vv.start();}@Overridepublic void onCompletion(MediaPlayer mp) {// TODOToast.makeText(getApplicationContext(), "播放完了", 0).show();}@Overridepublic boolean onError(MediaPlayer mp, int what, int extra) {Toast.makeText(getApplicationContext(), "资源有问题", 0).show();// TODOreturn false;}@Overridepublic void onPrepared(MediaPlayer mp) {Toast.makeText(getApplicationContext(), "准备好了", 0).show();// TODO}}

 

22. vitamio的mediaplay的集成

1.相关配置见21.

2.MainActivity.java

public class MainActivity extends Activity implements OnErrorListener, OnPreparedListener, OnCompletionListener {private MediaPlayer mMediaPlayer;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);//使用vitamio需要初始化引擎,引擎的检查/**---------------需要注意 begin---------------**/if (!LibsChecker.checkVitamioLibs(this))return;/**---------------需要注意 end---------------**/}public void click(View v) {try {mMediaPlayer = new MediaPlayer(this);mMediaPlayer.setOnErrorListener(this);mMediaPlayer.setOnPreparedListener(this);mMediaPlayer.setOnCompletionListener(this);mMediaPlayer.reset();mMediaPlayer.setDataSource("mms://mediasrv2.iptv.xmg.com.cn/yinyue");mMediaPlayer.prepareAsync();} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();}}@Overridepublic void onCompletion(MediaPlayer mp) {Toast.makeText(getApplicationContext(), "播放完了", 0).show();}@Overridepublic void onPrepared(MediaPlayer mp) {Toast.makeText(getApplicationContext(), "准备好了", 0).show();mMediaPlayer.start();}@Overridepublic boolean onError(MediaPlayer mp, int what, int extra) {Toast.makeText(getApplicationContext(), "资源有问题", 0).show();// TODOreturn true;}@Overrideprotected void onDestroy() {if (mMediaPlayer != null) {mMediaPlayer.release();mMediaPlayer = null;}super.onDestroy();}}

 

22.百度媒体云介绍

1.百度媒体云

 

2.也可以单独作为播放器使用

 

23.百度媒体云运行demo总结

1.介绍:http://developer.baidu.com/cloud/media,或者直接百度`百度媒体云`
2. 下载: http://developer.baidu.com/wiki/index.php?title=docs/cplat/media/video/sdk

3.集成方式

(1) 共享播放引擎方案:如果你的手机里面有了播放引擎就直接相互使用.如果没有,对其进行下载
     1. 优点:工程大小比较下;
     2. 缺点:如果用户手机之前没有安装播放引擎.然用户去安装引擎,用户体验差,很多用户都不接受
(2). Jar+so动态库方案:在工程里面直接集成jar+so动态库
     1. 优点:不用管手机里面是否有播放引擎
     2. 缺点:那么工程会大6m左右;

4.百度媒体云运行demo总结
(1)本地:支持所有格式
(2)网络:支持所有格式
(3)流媒体:支持mms rtsp支持   m3u8支持

 

24.媒体云的集成_共享播放引擎的方式

1. 修改AndroidManifest.xml文件-->添加activity或者添加权限

    包名需要自己修改

<!-- 百度媒体云.播放视频需要的activity -->        <activityandroid:name="com.baidu.cyberplayersdksample1.VideoViewPlayingActivity"            android:configChanges="keyboardHidden|orientation"            android:exported="true"            android:label="PlayingActivity"            android:screenOrientation="landscape"            android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >            <intent-filter>                <action android:name="android.intent.action.VIEW" />                <category android:name="android.intent.category.DEFAULT" />                <category android:name="android.intent.category.BROWSABLE" />            </intent-filter>        </activity> <uses-permission android:name="android.permission.INTERNET" />    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />    <uses-permission android:name="android.permission.WRITE_SETTINGS" />    <uses-permission android:name="android.permission.READ_PHONE_STATE" />    <uses-permission android:name="android.permission.WAKE_LOCK" />

2. 添加`Baidu_CyberPlayer_SDK_Android.jar`
3. 写代码-->参考demo
