最近公司让做一个android视屏播放器的项目，本人也查看了网上很多的开源视频sdk,综合播放控制界面的定制化和sdk本身的功能多样化选择了VLC,这是一个功能强大的可以在多个终端使用的播放sdk；
本来按照预先制定的计划一步步开发一切顺利。但是当进行到竖频播放器要和横屏播放器自由切换时，问题就来了。最开始的思路是将切换时改变播放view宽高参数，但是经过尝试发现不好用，会出现黑屏，个人判断原因是宽高比变换后需要重绘SurfaceView。所以单纯想改变宽高来实现横竖屏切换的计划失败了。然后我就想着使用切屏时加载不同的布局，然后重绘SurfaceView,再重新绑定。经过测试可以实现。
首先需要将播放activity实现SurfaceHolder.Callback接口，这样可以在切屏时重绘布局，然后加上一些播放控件，代码如下：

这个虽然大致上能够实现需求中需要的布局,但是在重复测试中发现了一些问题：比如说可能存在切换不稳定的情况，偶尔会出现黑屏；在添加附加控制功能时也出现了一些困难；所以这个版本还不堪商用，需要持续改进。git代码:vlc-cutscreen-demo.
