用法

1. sdk集成

首先，下载最新版本的
PLDroidPlayer SDK

2. 导入 SDK

3. 添加依赖

compile files('libs/pldroid-player-1.3.1.jar')
compile 'com.qiniu:happy-dns:0.2.+'
compile 'com.qiniu.pili:pili-android-qos:0.8.+'

4. 添加权限

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

5. 布局

<com.pili.pldroid.player.widget.PLVideoTextureView
    android:id="@+id/videoView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_centerInParent="true"/>

6. 播放器设置（需要用到sdk中demo里的MediaController）

6.1 初始化

mVideoView = (PLVideoTextureView) findViewById(R.id.videoView);

6.2 设置加载动画

mLoadingView = (ProgressBar) findViewById(R.id.LoadingView);
mVideoView.setBufferingIndicator(mLoadingView);

6.3 音量与亮度的初始化

mVolumeBrightnessLayout = findViewById(R.id.operation_volume_brightness);
mOperationBg = (ImageView) findViewById(R.id.operation_bg);
mOperationPercent = (ImageView) findViewById(R.id.operation_percent);

6.4 获取最大音量

mAudioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
mMaxVolume = mAudioManager
            .getStreamMaxVolume(AudioManager.STREAM_MUSIC);

6.5 初始化手势识别器

mGestureDetector = new GestureDetector(this, new VideoActivity.MyGestureListener());

6.6 播放参数配置

    AVOptions options = new AVOptions();

    // the unit of timeout is ms

    // 准备超时时间，包括创建资源、建立连接、请求码流等，单位是 ms
    // 默认值是：无
    options.setInteger(AVOptions.KEY_PREPARE_TIMEOUT, 10 * 1000);
    options.setInteger(AVOptions.KEY_GET_AV_FRAME_TIMEOUT, 10 * 1000);
    // Some optimization with buffering mechanism when be set to 1
    // 解码方式，codec＝1，硬解; codec=0, 软解
    // 默认值是：0
    int isLiveStreaming =IS_LIVE_STREAMING;
    options.setInteger(AVOptions.KEY_LIVE_STREAMING, isLiveStreaming);
    // 当前播放的是否为在线直播，如果是，则底层会有一些播放优化
    // 默认值是：0
    if (isLiveStreaming == 1) {
        // 是否开启"延时优化"，只在在线直播流中有效
        // 默认值是：0
        options.setInteger(AVOptions.KEY_DELAY_OPTIMIZATION, 1);
    }

    // 1 -> hw codec enable, 0 -> disable [recommended]
//        int codec = getIntent().getIntExtra("mediaCodec", 0);
    int codec = MEDIA_CODEC;
    // 解码方式，codec＝1，硬解; codec=0, 软解
    // 默认值是：0
    options.setInteger(AVOptions.KEY_MEDIACODEC, codec);

    // whether start play automatically after prepared, default value is 1
    options.setInteger(AVOptions.KEY_START_ON_PREPARED, 0);

    mVideoView.setAVOptions(options);

6.7 关联播放控制器

 // You can also use a custom `MediaController` widget
    mMediaController = new MediaController(this, false, isLiveStreaming == 1);
    mVideoView.setMediaController(mMediaController);

6.8 设置播放监听

    mVideoView.setOnInfoListener(mOnInfoListener);
    // mVideoView.setOnVideoSizeChangedListener(mOnVideoSizeChangedListener);
    mVideoView.setOnBufferingUpdateListener(mOnBufferingUpdateListener);
    mVideoView.setOnCompletionListener(mOnCompletionListener);
    mVideoView.setOnSeekCompleteListener(mOnSeekCompleteListener);
    mVideoView.setOnErrorListener(mOnErrorListener);
    mVideoView.setVideoPath(mVideoPath);
    mVideoView.setDisplayAspectRatio(mDisplayAspectRatio);
    mVideoView.setOnPreparedListener(mOnPreparedListener);

6.9 根据尺寸旋转方向监听

    mVideoView.setOnVideoSizeChangedListener(new PLMediaPlayer.OnVideoSizeChangedListener() {
        @Override
        public void onVideoSizeChanged(PLMediaPlayer plMediaPlayer, int width, int height) {
//                Logger.i("width:" + width + "---heightL:" + height);
            System.out.println("width:" + width + "---heightL:" + height);
            if (width > height&&mVideoRotation==0) {
                //旋转方向
                System.out.println("旋转方向");
                setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
            }
            //如果视频角度是90度
            if(mVideoRotation==90)
            {
                //旋转视频
                System.out.println("旋转方向" + mVideoRotation);
                mVideoView.setDisplayOrientation(270);
            }


        }
    });

6.10 开启播放器

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

7. 播放器监听实现

7.1 旋转角度

public void onClickRotate(View v) {
    mRotation = (mRotation + 90) % 360;
    mVideoView.setDisplayOrientation(mRotation);
}

7.2 缓冲设置

private PLMediaPlayer.OnInfoListener mOnInfoListener = new PLMediaPlayer.OnInfoListener() {
    @Override
    public boolean onInfo(PLMediaPlayer plMediaPlayer, int what, int extra) {
        switch (what) {
            case PLMediaPlayer.MEDIA_INFO_BUFFERING_START:
                System.out.println("正在缓冲----\"");
                //开始缓存，暂停播放
                if (mVideoView != null) {
                    mVideoView.pause();
                }
                needResume = true;
                mLoadingView.setVisibility(View.VISIBLE);
                break;
            case PLMediaPlayer.MEDIA_INFO_BUFFERING_END:
            case PLMediaPlayer.MEDIA_INFO_VIDEO_RENDERING_START:
                System.out.println("缓冲完成----");
                //缓存完成，继续播放
                if (needResume)
                    if (mVideoView != null) {
                        mVideoView.start();
                    }
                mLoadingView.setVisibility(View.GONE);
                break;
            case PLMediaPlayer.MEDIA_INFO_BUFFERING_BYTES_UPDATE:
                //显示 下载速度
                System.out.println("download rate:" + extra);
                //mListener.onDownloadRateChanged(arg2);
                break;
            case 10001:
                //保存视频角度
                mVideoRotation=extra;

                break;
        }
        System.out.println("onInfo:" + what + "___" + extra);
        return false;
    }
}

7.3 手势监听实现

private class MyGestureListener extends GestureDetector.SimpleOnGestureListener {

    /** 双击 */
    @Override
    public boolean onDoubleTap(MotionEvent e) {

        if(mDisplayAspectRatio == PLVideoTextureView.ASPECT_RATIO_FIT_PARENT){
            mDisplayAspectRatio = PLVideoTextureView.ASPECT_RATIO_PAVED_PARENT;
        }else {
            mDisplayAspectRatio = PLVideoTextureView.ASPECT_RATIO_FIT_PARENT;
        }

        if (mVideoView != null) mVideoView.setDisplayAspectRatio(mDisplayAspectRatio);
        return true;
    }

    /** 滑动 */
    @Override
    public boolean onScroll(MotionEvent e1, MotionEvent e2,
                            float distanceX, float distanceY) {
        float mOldX = e1.getX(), mOldY = e1.getY();
        int y = (int) e2.getRawY();
        Display disp = getWindowManager().getDefaultDisplay();
        int windowWidth = disp.getWidth();
        int windowHeight = disp.getHeight();

        if (mOldX > windowWidth * 4.0 / 5)// 右边滑动
            onVolumeSlide((mOldY - y) / windowHeight);
        else if (mOldX < windowWidth / 5.0)// 左边滑动
            onBrightnessSlide((mOldY - y) / windowHeight);

        return super.onScroll(e1, e2, distanceX, distanceY);
    }
}

7.4 改变声音大小

private void onVolumeSlide(float percent) {
    if (mVolume == -1) {
        mVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
        if (mVolume < 0)
            mVolume = 0;

        // 显示
        mOperationBg.setImageResource(R.drawable.video_volumn_bg);
        mVolumeBrightnessLayout.setVisibility(View.VISIBLE);
    }

    int index = (int) (percent * mMaxVolume) + mVolume;
    if (index > mMaxVolume)
        index = mMaxVolume;
    else if (index < 0)
        index = 0;

    // 变更声音
    mAudioManager.setStreamVolume(AudioManager.STREAM_MUSIC, index, 0);
    // 变更进度条
    ViewGroup.LayoutParams lp = mOperationPercent.getLayoutParams();
    lp.width = findViewById(R.id.operation_full).getLayoutParams().width
            * index / mMaxVolume;
    mOperationPercent.setLayoutParams(lp);
}

7.5 滑动改变亮度

private void onBrightnessSlide(float percent) {
    if (mBrightness < 0) {
        mBrightness = getWindow().getAttributes().screenBrightness;
        if (mBrightness <= 0.00f)
            mBrightness = 0.50f;
        if (mBrightness < 0.01f)
            mBrightness = 0.01f;

        // 显示
        mOperationBg.setImageResource(R.drawable.video_brightness_bg);
        mVolumeBrightnessLayout.setVisibility(View.VISIBLE);
    }
    WindowManager.LayoutParams lpa = getWindow().getAttributes();
    lpa.screenBrightness = mBrightness + percent;
    if (lpa.screenBrightness > 1.0f)
        lpa.screenBrightness = 1.0f;
    else if (lpa.screenBrightness < 0.01f)
        lpa.screenBrightness = 0.01f;
    getWindow().setAttributes(lpa);

    ViewGroup.LayoutParams lp = mOperationPercent.getLayoutParams();
    lp.width = (int) (findViewById(R.id.operation_full).getLayoutParams().width * lpa.screenBrightness);
    mOperationPercent.setLayoutParams(lp);
}

总结

这是自己在学习android视频播放的一个demo，只是基本使用，其中还有许多缺陷。
