PLDroidPlayer

PLDroidPlayer 是一个适用于 Android 平台的音视频播放器 SDK，可高度定制化和二次开发，为 Android 开发者提供了简单、快捷的接口，帮助开发者在 Android 平台上快速开发播放器应用。

PLDroidPlayer目前基于ijkplayer, 感谢 ijkplayer ，相应的修改详见：https://github.com/pili-engineering/ijkplayer

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

5. 布局

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。
