导入方式

gradle导入

allprojects {
    repositories {
        jcenter()
    }
}

dependencies {
    # 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: optional
    compile '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, experimental
    compile 'tv.danmaku.ijk.media:ijkplayer-exo:0.8.8'
}

从github下载ijkplayer源码，进行编译

待实践

来个栗子

compile 'tv.danmaku.ijk.media:ijkplayer-java:0.8.8'
    compile 'tv.danmaku.ijk.media:ijkplayer-armv7a:0.8.8'

    compile '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'

    compile 'tv.danmaku.ijk.media:ijkplayer-exo:0.8.8'

VideoPlayer(ijk没有给具体的view，需要我们自己封装)

public class VideoPlayer extends FrameLayout {
    private Context mContext;
    private IMediaPlayer mMediaPlayer;
    private SurfaceView surfaceView;

    public VideoPlayer(Context context) {
        super(context);
    }

    public VideoPlayer(Context context, AttributeSet attrs) {
        super(context, attrs);
        init(context);
    }

    private void init(Context context) {
        mContext = context;
        createSurfaceView();
    }

    private void createSurfaceView() {
        surfaceView = new SurfaceView(mContext);
        surfaceView.getHolder().addCallback(new SurfaceHolder.Callback() {
            @Override
            public void surfaceCreated(SurfaceHolder holder) {

            }

            @Override
            public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
                if (mMediaPlayer != null) {
                    mMediaPlayer.setDisplay(holder);
                }
            }

            @Override
            public void surfaceDestroyed(SurfaceHolder holder) {

            }
        });
        LayoutParams layoutParams =
                new LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT,
                        Gravity.CENTER);
        addView(surfaceView, 0, layoutParams);
    }

    //创建一个新的player
    private IMediaPlayer createPlayer() {
        //todo 各个参数的含义
        IjkMediaPlayer ijkMediaPlayer = new IjkMediaPlayer();
        ijkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "opensles", 1);

        ijkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "overlay-format", IjkMediaPlayer.SDL_FCC_RV32);
        ijkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "framedrop", 1);
        ijkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "start-on-prepared", 0);

        ijkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "http-detect-range-support", 1);

        ijkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_CODEC, "skip_loop_filter", 48);
        ijkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_CODEC, "min-frames", 100);
        ijkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "enable-accurate-seek", 1);

        ijkMediaPlayer.setVolume(1.0f, 1.0f);

        return ijkMediaPlayer;
    }

    //开始加载视频
    public void load(String mPath) throws IOException {
        if (mMediaPlayer != null) {
            mMediaPlayer.stop();
            mMediaPlayer.release();
        }
        mMediaPlayer = createPlayer();
        setListener(mMediaPlayer);
        mMediaPlayer.setDisplay(surfaceView.getHolder());
        mMediaPlayer.setDataSource(mContext, Uri.parse(mPath));
        mMediaPlayer.prepareAsync();
    }

    private void setListener(IMediaPlayer player) {
        player.setOnPreparedListener(new IMediaPlayer.OnPreparedListener() {
            @Override
            public void onPrepared(IMediaPlayer iMediaPlayer) {
                if (mMediaPlayer != null) {
                    mMediaPlayer.start();
                }
            }
        });
        player.setOnVideoSizeChangedListener(new IMediaPlayer.OnVideoSizeChangedListener() {
            @Override
            public void onVideoSizeChanged(IMediaPlayer iMediaPlayer, int i, int i1, int i2, int i3) {

            }
        });
    }

    public void release() {
        if (mMediaPlayer != null) {
            mMediaPlayer.reset();
            mMediaPlayer.release();
            mMediaPlayer = null;
        }
    }

    public void pause() {
        if (mMediaPlayer != null) {
            mMediaPlayer.pause();
        }
    }

    public void stop() {
        if (mMediaPlayer != null) {
            mMediaPlayer.stop();
        }
    }

    public void reset() {
        if (mMediaPlayer != null) {
            mMediaPlayer.reset();
        }
    }

}

MainActivity

VideoPlayer videoPlayer = findViewById(R.id.video);

        try {
            videoPlayer.load("http://vjs.zencdn.net/v/oceans.mp4");
        } catch (IOException e) {
            Toast.makeText(this,"播放失败",Toast.LENGTH_SHORT);
            e.printStackTrace();
        }

效果：
