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][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：

**我们下载完成，进入android/ijkplayer目录：**

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。** .

![这里写图片描述][SouthEast 1]

**（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：

1.  使用Vitamio的VideoView进行视频播放
2.  视频左侧界面（左1/2以内）上下滑动调节亮度
3.  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
4.  非直播状态，可以左右滑动调节当前播放进度
