Android ijkplayer的使用方法解析

ijkplayer是Bilibili基于ffmpeg开发并开源的轻量级视频播放器，支持播放本地网络视频，也支持流媒体播放。支持Android&iOS。

ijkplayer的编译这里不多阐述，我也是直接获取别人编译完成的so库文件，直接使用的。如果你对ijkplayer的编译感兴趣，可以百度一下，有很多文章。

使用ijkplayer

导包

ijkplayer源码官方下载地址：https://github.com/Bilibili/ijkplayer

上面是官方提供的ijkplayer的源码地址，但是它是没有编译过的。下面我给大家分享一份编译好的ijkplayer源码，由于比较大，分了三个包才上传完成，需要三个包都下载后才能一起解压： ijkplayer_jb51.rar

我们下载完成，进入android/ijkplayer目录：

Android ijkplayer的使用方法解析

ijkplayer-java：ijkplayer的一些操作封装及定义。这里面是通用的API接口，里面最主要的是IMediaPlayer，它是用来渲染显示多媒体的。
ijkplayer-exo：google开源的一个新的播放器ExoPlayer，在Demo中和ijkplayer对比用的。通过安装ijkplayer可以发现setting里面可以选择不同player来渲染多媒体显示，该模块下面就是一个MediaPlayer。
ijkplayer-example：测试程序
ijkplayer-{arch}：编译出来的各个版本的.so文件。

官方提供的Demo的代码还是挺多的，甚至还用了otto,需要对官方的demo进行精简，去除一些用不到的代码。

首先需要的是ijkplayer-{arch}、ijkplayer-java两个库。exo是Google提供的新的播放器，这里不需要，直接砍掉。其次是ijkplayer-example里的，我们需要的只有tv.danmaku.ijk.media.example.widget.media包下的部分类。

注：

链接库ijkplayer-arm64，ijkplayer-armv5，ijkplayer-armv7a，ijkplayer-x86，ijkplayer-x86_64是不同体系架构的动态链接库，在当前工程结构里面作为一个模块，如果不想做兼容多平台问题，可以删除其他目录结构，单独保留自己需要的平台目录。

新建一个工程：

（1）把ijkplayer-armv7a/src/main/libs下的文件拷贝到新工程app目录的libs下。
（2）把ijkplayer-java/build/outputs/aar/ijkplayer-java-release.aar复制到新工程app目录的libs下。
（3）修改APP下的build.gradle, 主要设置.so及.aar的位置:

apply plugin: 'com.android.application'

android {
  compileSdkVersion 24
  buildToolsVersion "25.0.0"
  defaultConfig {
    applicationId "com.hx.ijkplayer_demo"
    minSdkVersion 14
    targetSdkVersion 24
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
  }
  buildTypes {
    release {
      minifyEnabled false
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
  }
  sourceSets {
    main {
      jniLibs.srcDirs = ['libs'] /**在libs文件夹下找so文件*/
    }
  }
}

repositories {
  mavenCentral()
  flatDir {
    dirs 'libs' /**在libs文件夹下找aar文件*/
  }
}

dependencies {
  compile fileTree(dir: 'libs', include: ['*.jar'])
  androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
  })
  compile 'com.android.support:appcompat-v7:24.2.1'
  testCompile 'junit:junit:4.12'
  compile(name: 'ijkplayer-java-release', ext: 'aar') /**编译ijkplayer-java-release.aar文件*/
}

（4）复制ijkplayer-example下面的tv.danmaku.ijk.media.example.widget.media到新的工程，删掉一些不需要类。

（5）IjkVideoView里面还是有很多如exo等没用的东西，删！具体可以参见我后面的Demo。

（6）Manifest

...
<activity android:name=".MainActivity"
     android:screenOrientation="sensorLandscape"
     android:configChanges="orientation|keyboardHidden">
...
</activity>
...
<uses-permission android:name="android.permission.INTERNET"/>

封装ijkplayer

上面只是ijkplayer的一个基本用法。我们可以对ijkplayer进行一次封装，让ijkplayer使用起来更加简单。

功能：

使用Vitamio的VideoView进行视频播放
视频左侧界面（左1/2以内）上下滑动调节亮度
视频右侧界面（右1/2以外）上下滑动调节声音
双击切换视频窗口布局
非直播状态，可以左右滑动调节当前播放进度

使用封装后的PlayerManager播放视频：

public class MainActivity extends AppCompatActivity implements PlayerManager.PlayerStateListener{

  private String url4 = "http://42.96.249.166/live/24035.m3u8";
  private PlayerManager player;

  @Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    initPlayer();
  }

  private void initPlayer() {
    player = new PlayerManager(this);
    player.setFullScreenOnly(true);
    player.setScaleType(PlayerManager.SCALETYPE_FILLPARENT);
    player.playInFullScreen(true);
    player.setPlayerStateListener(this);
    player.play(url1);

  @Override

  @Override
