ijkplayer播放器詳解使用教程

1.認識ijkplayer

最近公司準備開發一款視頻播放及直播的應用，找了許多開源的框架，大部分都是基於ffmpeg開發的。最開始準備用Vitamio框架開發的，相關的文章也比較豐富，結果對於非個人移動應用均需購買Vitamio使用授權。不過B站開源的ijkplayer也不錯，而且也不需要商業授權。
ijkplayer是一個基於FFmpeg的輕量級Android/iOS視頻播放器。FFmpeg的是全球領先的多媒體框架，能夠解碼，編碼，轉碼，複用，解複用，流，過濾器和播放大部分的視頻格式。它提供了錄製、轉換以及流化音視頻的完整解決方案。它包含了非常先進的音頻/視頻編解碼庫libavcodec，爲了保證高可移植性和編解碼質量，libavcodec裏很多code都是從頭開發的。

2.環境配置

項目中引入ijkplayer環境有兩種方式。

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下編譯源碼得到

Ubuntu需要安裝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

開始編譯

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

目錄結構

3.播放器使用

可能是網絡的問題，使用Gradle導入會花費很長時間，如果遇到超時，還得重頭來一遍，太費時間了。後來我就直接在Ubuntu下編譯後，在Android Studio下導入該項目。我先介紹下Demo中利用ijkplayer播放視頻的過程。

3.1初始化播放器

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

3.2初始化IjkVideoView

//這裏使用的是Demo中提供的AndroidMediaController類控制播放相關操作
mMediaController = new AndroidMediaController(this, false);
mMediaController.setSupportActionBar(actionBar);
mVideoView = (IjkVideoView) findViewById(R.id.video_view);
mVideoView.setMediaController(mMediaController);

3.3設置本地視頻文件位置或服務器地址，然後播放

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

3.4Activity銷燬時，需要釋放資源

@Override
public void onBackPressed() {
	mBackPressed = true;
	super.onBackPressed();
}
@Override
protected void onStop() {
	super.onStop();
	//點擊返回或不允許後臺播放時 釋放資源
	if (mBackPressed || !mVideoView.isBackgroundPlayEnabled()) {
	    mVideoView.stopPlayback();
	    mVideoView.release(true);
	    mVideoView.stopBackgroundPlay();
    } else {
        mVideoView.enterBackground();
    }
    IjkMediaPlayer.native_profileEnd();
}

4.自定義播放器

當然官方提供的Demo只是演示視頻播放的基本操作，對於視頻播放的控制、全屏等操作，還要自己動手做。

4.1部分聲明

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視頻播放比例

這裏需要修改IjkVideoView部分代碼後，才支持按比例播放

//修改相關代碼
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;
}

設置視頻播放比例

public void setScreenRate(int rate) {
	int width = 0;
    int height = 0;
    if (getRequestedOrientation() == ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) {// 橫屏
	    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 { //豎屏
        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屏幕方向切換

private void fullChangeScreen() {
	if (getRequestedOrientation() == ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) {// 切換爲豎屏
		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);
	//重新獲取屏幕寬高
    initScreenInfo();
    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {//切換爲橫屏
	    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播放進度

seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
	....
    @Override
    public void onStopTrackingTouch(SeekBar seekBar) {
         video.seekTo(seekBar.getProgress()*video.getDuration()/100);
         ...
    }
});
//視頻開始播放時使用handle.sendMessageDelayed更新時間顯示
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);
}
