Android ijkplayer详解使用教程

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Android/iOS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

# required

allprojects {

    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, Git, yasm

# install homebrew, git, yasm

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

brew install git

brew install yasm

# add these lines to your ~/.bash_profile or ~/.profile

# export ANDROID_SDK=<your sdk path>

# export ANDROID_NDK=<your ndk path>

# on Cygwin (unmaintained)

# install git, make, yasm

开始编译

git clone https://github.com/Bilibili/ijkplayer.git ijkplayer-android

cd ijkplayer-android

git checkout -B latest k0.6.1

./init-android.sh

cd android/contrib

./compile-ffmpeg.sh clean

./compile-ffmpeg.sh all

cd ..

./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android 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

@Override

public void onBackPressed() {

    mBackPressed = true;

    super.onBackPressed();

}

@Override

protected 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;//0

private int mCurrentAspectRatio = s_allAspectRatio[3];//0

private 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

@Override

public 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);

}
