下面简单介绍一下ijkplayer的使用

ijkplayer是b站基于FFmpeg开源的播放器，ijkplayer提供了个IjkMediaPlayer，功能和用法跟MediaPlayer类似，但是强大很多

官网Github

一、ijkplayer使用

1、新建一个Android项目，并在app的gradle下的dependencies中添加下面代码，其中ijkplayer-java是核心代码必须添加，IjkMediaPlayer就在这里面。ijkplayer-armv7a是armeabi-v7a下的so库，ijkplayer-armv5是armeabi下的so库，ijkplayer-arm64是arm64-v8a下的so库，ijkplayer-x86是x86下的so库，ijkplayer-x86_64是x86_64下的so库，根据项目选择添加即可，一般一套armeabi-v7a就可以了。ijkplayer-exo是谷歌下的IjkExoMediaPlayer，如果需要使用的话可以添加。

    # required, enough for most devices.compile 'tv.danmaku.ijk.media:ijkplayer-java:0.8.8'compile 'tv.danmaku.ijk.media:ijkplayer-armv7a:0.8.8'# Other ABIs: optionalcompile 'tv.danmaku.ijk.media:ijkplayer-armv5:0.8.8'compile 'tv.danmaku.ijk.media:ijkplayer-arm64:0.8.8'compile 'tv.danmaku.ijk.media:ijkplayer-x86:0.8.8'compile 'tv.danmaku.ijk.media:ijkplayer-x86_64:0.8.8'# ExoPlayer as IMediaPlayer: optional, experimentalcompile 'tv.danmaku.ijk.media:ijkplayer-exo:0.8.8'

2、在AndroidManifest.xml中添加网络权限

<uses-permission android:name="android.permission.INTERNET" />

3、使用SurfaceView播放视频

<SurfaceViewandroid:id="@+id/surface_view"android:layout_width="match_parent"android:layout_height="200dp" />

public class MainActivity extends AppCompatActivity {private SurfaceView surfaceView;private IjkMediaPlayer mPlayer;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);surfaceView = findViewById(R.id.surface_view);surfaceView.getHolder().addCallback(callback);}private void createPlayer() {if (mPlayer == null) {mPlayer = new IjkMediaPlayer();mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);try {mPlayer.setDataSource("http://9890.vod.myqcloud.com/9890_4e292f9a3dd011e6b4078980237cc3d3.f30.mp4");} catch (IOException e) {e.printStackTrace();}mPlayer.prepareAsync();}}private void release() {if (mPlayer != null) {mPlayer.stop();mPlayer.release();mPlayer = null;}IjkMediaPlayer.native_profileEnd();}private SurfaceHolder.Callback callback = new SurfaceHolder.Callback() {@Overridepublic void surfaceCreated(SurfaceHolder holder) {createPlayer();mPlayer.setDisplay(surfaceView.getHolder());}@Overridepublic void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {}@Overridepublic void surfaceDestroyed(SurfaceHolder holder) {if (surfaceView != null) {surfaceView.getHolder().removeCallback(callback);surfaceView = null;}}};@Overrideprotected void onDestroy() {super.onDestroy();release();}}

4、使用TextureView播放视频

<TextureViewandroid:id="@+id/texture_view"android:layout_width="match_parent"android:layout_height="200dp" />

public class MainActivity extends AppCompatActivity {private TextureView textureView;private Surface mSurface;private IjkMediaPlayer mPlayer;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);textureView = findViewById(R.id.texture_view);textureView.setSurfaceTextureListener(listener);}private void createPlayer() {if (mPlayer == null) {mPlayer = new IjkMediaPlayer();mPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "start-on-prepared", 0);mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);try {mPlayer.setDataSource("http://9890.vod.myqcloud.com/9890_4e292f9a3dd011e6b4078980237cc3d3.f30.mp4");} catch (IOException e) {e.printStackTrace();}mPlayer.prepareAsync();}}private void release() {if (mPlayer != null) {mPlayer.stop();mPlayer.release();mPlayer = null;}IjkMediaPlayer.native_profileEnd();}private TextureView.SurfaceTextureListener listener = new TextureView.SurfaceTextureListener() {@Overridepublic void onSurfaceTextureAvailable(SurfaceTexture surface, int width, int height) {createPlayer();mSurface = new Surface(surface);mPlayer.setSurface(mSurface);}@Overridepublic void onSurfaceTextureSizeChanged(SurfaceTexture surface, int width, int height) {}@Overridepublic boolean onSurfaceTextureDestroyed(SurfaceTexture surface) {textureView.setSurfaceTextureListener(null);textureView = null;mSurface = null;return true;}@Overridepublic void onSurfaceTextureUpdated(SurfaceTexture surface) {}};@Overrideprotected void onDestroy() {super.onDestroy();release();}}

二、其他设置

// 设置倍速，MediaPlayer是不支持的
mPlayer.setSpeed(1.0f);// 设置不自动播放（ijkPlayer默认准备就自动播放）
mPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "start-on-prepared", 0);// 设置编码方式 1:硬编码 0:软编码
mPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "mediacodec", 1);...// 一些监听
setOnPreparedListener
setOnCompletionListener
setOnErrorListener

上面为IjkMediaPlayer的基本设置，其他具体根据项目要求再设置，不过使用上面用法不支持https，可以把上面视频地址改为https的，上面地址支持https的，可以在浏览器中测试，在Demo里就播不了，报下面错误。因为上面Bilibili上面提供的用法不支持https，想要支持的话需要自己编译，下篇文章将介绍自己编译ijkplayer。
