Android(安卓)用SurfaceView+PLMediaPlayer 打造一个平板端的网络播放器
16lz
2021-01-26
最近我开始做我接手的项目中最后一个模块：微课。真的太累了，前所未有的累过，感觉身体被掏空。也让我不停的思考，究竟什么是高效，难道人多就是高效？
之前闲来无事的时候写过一个播放器，但好像跟网络播放器不搭，因为不会有任何一家软件公司会把核心视频不做任何处理的挂在服务器上的。然而关于视频的解码与解密我真的是一窍不通啊，不懂c语言，也就无法再android运用c库，再次暴露了自己的弱点。
要求：1.对视频边解码边播放边缓存
2.全屏与半屏
3.手势
效果：
准备：
PLMediaPlayer 使用的github上别人封装的播放器 点击打开链接
遵循的原则：当surfaceview创建的时候，再初始化PLMediaPlayer，当PLMediaPlayer 准备好的时候再播放或 者初始化控制栏与手势
先贴上我写的完整代码：（缺滑动seekbar视频跳转）

<?xml version="1.0" encoding="utf-8"?> 1.因为是平板端，默认都是横屏的，所以我就需要什么重力切换横竖屏的功能，只需要将屏幕切换到满屏以及还原。所以我必须要记录屏幕的宽高以及原来组件的宽高。测量组件宽高的代码宽高之测量一次（）：
ViewTreeObserver vto2 = ll_video.getViewTreeObserver(); vto2.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() { @Override public void onGlobalLayout() { ll_video.getViewTreeObserver().removeGlobalOnLayoutListener(this); Logger.i("当前宽度DDD:" + ll_video.getWidth() + "/" + ll_video.getHeight()); wytVideoPlayView.setInitialWidth(ll_video.getWidth()); wytVideoPlayView.setInitialHeight(ll_video.getHeight()); ViewGroup.LayoutParams layoutParams = wytVideoPlayView.getLayoutParams(); layoutParams.width = ll_video.getWidth(); layoutParams.height = ll_video.getHeight(); wytVideoPlayView.setLayoutParams(layoutParams); } }); //获取状态栏的高度 private int getStatusBarHeight() { int result = 0; int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android"); if (resourceId > 0) { result = getResources().getDimensionPixelSize(resourceId); } return result; } public void fullScreen() { DisplayMetrics dm = getResources().getDisplayMetrics(); Logger.i(TAG + "屏幕" + dm.widthPixels + "/" + dm.heightPixels); ViewGroup.LayoutParams layoutParams = getLayoutParams(); layoutParams.width = dm.widthPixels; layoutParams.height = dm.heightPixels - getStatusBarHeight(); setLayoutParams(layoutParams); isFullScreen = true; iv_full.setSelected(isFullScreen); mSurfaceView.setLayoutParams(layoutParams); }2.用于缓冲的加载的view究竟什么时候显示：
我是在缓冲的时候显示，在缓冲结束隐藏，在获取第一帧图隐藏
3.缓冲的时候如何加载当前网速：

gestureDetector = new GestureDetector(currentContext, new GestureDetector.SimpleOnGestureListener() { //双击 @Override public boolean onDoubleTap(MotionEvent e) { if (isFullScreen) { nofullScreen(); showToastTips("还原"); } else { fullScreen(); showToastTips("全屏"); } return true; } @Override public void onShowPress(MotionEvent e) { super.onShowPress(e); showOrHideController(); } /** * ,一次单独的轻击抬起操作,也就是轻击一下屏幕 * @param e * @return */ @Override public boolean onSingleTapUp(MotionEvent e) { return true; } @Override public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) { if (mGestureOperationType == GestureOperationType.NONE) { if (Math.abs(distanceX) > Math.abs(distanceY)) { //如果X轴的绝对值大于Y轴的绝对值 说明此时在快进或者快退 Log.i(TAG + "手势::", "快进快退"); mGestureOperationType = GestureOperationType.FASTFORWARDORBACKWARD; } else { if (e1.getX() < mSurfaceView.getWidth() / 2) { //说名在屏幕的左侧,左侧调节亮度 Log.i(TAG + "手势::", "亮度"); mGestureOperationType = GestureOperationType.BRIGHTNESS; } else { //右侧调节音量 Log.i(TAG + "手势::", "音量"); mGestureOperationType = GestureOperationType.VOLUME; } } } return DealWithScrollGestureOperation(e1, e2, distanceX, distanceY); } });要加上这一段：
/** * surfaceView的Touch监听 * * @param v * @param event * @return */ @Override public boolean onTouch(View v, MotionEvent event) { gestureDetector.onTouchEvent(event); int action = event.getActionMasked(); if (action == MotionEvent.ACTION_UP || action == MotionEvent.ACTION_CANCEL) { mGestureOperationType = GestureOperationType.NONE; } return true; }5.缓存：这个播放器不支持缓存，但它基于的 ijkplayer 是提供的。我用的是这个
