1.认识ijkplayer

最近公司准备开发一款视频播放及直播的应用，找了许多开源的框架，大部分都是基于ffmpeg开发的。最开始准备用Vitamio框架开发的，相关的文章也比较丰富，结果对于非个人移动应用均需购买Vitamio使用授权。不过B站开源的ijkplayer也不错，而且也不需要商业授权。

ijkplayer是一个基于FFmpeg的轻量级/视频播放器。FFmpeg的是全球领先的多媒体框架，能够解码，编码，转码，复用，解复用，流，过滤器和播放大部分的视频格式。它提供了录制、转换以及流化音视频的完整解决方案。它包含了非常先进的音频/视频编解码库libavcodec，为了保证高可移植性和编解码质量，libavcodec里很多code都是从头开发的。

2.环境配置

项目中引入ijkplayer环境有两种方式。

2.1在Gradle中引入

# requiredallprojects {    repositories {        jcenter()    }}dependencies {    # required, enough for most devices.    compile 'tv.danmaku.ijk.media:ijkplayer-java:0.6.1'    compile 'tv.danmaku.ijk.media:ijkplayer-armv7a:0.6.1'    # Other ABIs: optional    compile 'tv.danmaku.ijk.media:ijkplayer-armv5:0.6.1'    compile 'tv.danmaku.ijk.media:ijkplayer-arm64:0.6.1'    compile 'tv.danmaku.ijk.media:ijkplayer-x86:0.6.1'    compile 'tv.danmaku.ijk.media:ijkplayer-x86_64:0.6.1'    # ExoPlayer as IMediaPlayer: optional, experimental    compile 'tv.danmaku.ijk.media:ijkplayer-exo:0.6.1'}

2.2在Ubuntu下编译源码得到

Ubuntu需要安装homebrew, , yasm

# install homebrew, git, yasmruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"brew install gitbrew install yasm# add these lines to your ~/.bash_profile or ~/.profile# export ANDROID_SDK=
    
     # export ANDROID_NDK=
     
      # on Cygwin (unmaintained)# install git, make, yasm

开始编译

git clone https://github.com/Bilibili/ijkplayer.git ijkplayer-androidcd ijkplayer-androidgit checkout -B latest k0.6.1./init-android.shcd android/contrib./compile-ffmpeg.sh clean./compile-ffmpeg.sh allcd .../compile-ijk.sh all# Android Studio:#     Open an existing Android Studio project#     Select android/ijkplayer/ and import##     define ext block in your root build.gradle#     ext {
    #       compileSdkVersion = 23       // depending on your sdk version#       buildToolsVersion = "23.0.0" // depending on your build tools version##       targetSdkVersion = 23        // depending on your sdk version#     }## Eclipse: (obselete)#     File -> New -> Project -> Android Project from Existing Code#     Select android/ and import all project#     Import appcompat-v7#     Import preference-v7## Gradle#     cd ijkplayer#     gradle

3.播放器使用

可能是网络的问题，使用Gradle导入会花费很长时间，如果遇到超时，还得重头来一遍，太费时间了。后来我就直接在Ubuntu下编译后，在 Studio下导入该项目。我先介绍下Demo中利用ijkplayer播放视频的过程。

3.1初始化播放器

IjkMediaPlayer.loadLibrariesOnce(null);IjkMediaPlayer.native_profileBegin("libijkplayer.so");

3.2初始化IjkVideoView

//这里使用的是Demo中提供的AndroidMediaController类控制播放相关操作mMediaController = new AndroidMediaController(this, false);mMediaController.setSupportActionBar(actionBar);mVideoView = (IjkVideoView) findViewById(R.id.video_view);mVideoView.setMediaController(mMediaController);

3.3设置本地视频文件位置或服务器地址，然后播放

mVideoView.setVideoPath(mVideoPath);mVideoView.start();

3.4Activity销毁时，需要释放资源

@Overridepublic void onBackPressed() {    mBackPressed = true;    super.onBackPressed();}@Overrideprotected void onStop() {    super.onStop();    //点击返回或不允许后台播放时 释放资源    if (mBackPressed || !mVideoView.isBackgroundPlayEnabled()) {        mVideoView.stopPlayback();        mVideoView.release(true);        mVideoView.stopBackgroundPlay();    } else {        mVideoView.enterBackground();    }    IjkMediaPlayer.native_profileEnd();}

4.自定义播放器

当然官方提供的Demo只是演示视频播放的基本操作，对于视频播放的控制、全屏等操作，还要自己动手做。

4.1部分声明

private static final int SIZE_DEFAULT = 0;private static final int SIZE_4_3 = 1;private static final int SIZE_16_9 = 2;private int currentSize = SIZE_16_9;private IjkVideoView video;private SeekBar seekBar;

4.2视频播放比例

这里需要修改IjkVideoView部分代码后，才支持按比例播放

//修改相关代码private static final int[] s_allAspectRatio = {    IRenderView.AR_ASPECT_FIT_PARENT,    IRenderView.AR_ASPECT_FILL_PARENT,    IRenderView.AR_ASPECT_WRAP_CONTENT,    IRenderView.AR_MATCH_PARENT,    IRenderView.AR_16_9_FIT_PARENT,    IRenderView.AR_4_3_FIT_PARENT};private int mCurrentAspectRatioIndex = 3;//0private int mCurrentAspectRatio = s_allAspectRatio[3];//0private int mCurrentRender = RENDER_TEXTURE_VIEW;//增加下面方法public IRenderView getmRenderView() {    return mRenderView;}public int getmVideoWidth() {   return mVideoWidth;}public int getmVideoHeight() {   return mVideoHeight;}

设置视频播放比例

public void setScreenRate(int rate) {    int width = 0;    int height = 0;    if (getRequestedOrientation() == ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) {
   // 横屏        if (rate == SIZE_DEFAULT) {            width = video.getmVideoWidth();            height = video.getmVideoHeight();        } else if (rate == SIZE_4_3) {            width = screenHeight / 3 * 4;            height = screenHeight;        } else if (rate == SIZE_16_9) {            width = screenHeight / 9 * 16;            height = screenHeight;        }    } else { //竖屏        if (rate == SIZE_DEFAULT) {            width = video.getmVideoWidth();            height = video.getmVideoHeight();        } else if (rate == SIZE_4_3) {            width = screenWidth;            height = screenWidth * 3 / 4;        } else if (rate == SIZE_16_9) {            width = screenWidth;            height = screenWidth * 9 / 16;        }    }    if (width > 0 && height > 0) {        FrameLayout.LayoutParams lp = (FrameLayout.LayoutParams) video.getmRenderView().getView().getLayoutParams();        lp.width = width;        lp.height = height;        video.getmRenderView().getView().setLayoutParams(lp);    }}

4.3屏幕方向切换

private void fullChangeScreen() {    if (getRequestedOrientation() == ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) {
   // 切换为竖屏        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);    } else {        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);    }}

4.4全屏播放

@Overridepublic void onConfigurationChanged(Configuration newConfig) {    super.onConfigurationChanged(newConfig);    //重新获取屏幕宽高    initScreenInfo();    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {//切换为横屏        LinearLayout.LayoutParams lp = (LinearLayout.LayoutParams) video.getLayoutParams();        lp.height = screenHeight;        lp.width = screenWidth;        video.setLayoutParams(lp);    } else {        LinearLayout.LayoutParams lp = (LinearLayout.LayoutParams) video.getLayoutParams();        lp.height = screenWidth * 9 / 16;        lp.width = screenWidth;        video.setLayoutParams(lp);    }    setScreenRate(currentSize);}

4.5播放进度

seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {    ....    @Override    public void onStopTrackingTouch(SeekBar seekBar) {         video.seekTo(seekBar.getProgress()*video.getDuration()/100);         ...    }});//视频开始播放时使用handle.sendMessageDelayed更新时间显示private void refreshTime(){    int totalSeconds = video.getCurrentPosition() / 1000;    int seconds = totalSeconds % 60;    int minutes = (totalSeconds / 60) % 60;    int hours = totalSeconds / 3600;    String ti=hours > 0 ? String.format("%02d:%02d:%02d", hours, minutes, seconds):String.format("%02d:%02d", minutes, seconds);    time.setText(ti);}
