1、WallpaperGLThread
2、GLMediaDisplay
3、GLRenderer
4、GLImageRenderer
5、GLVideoRenderer
问题：
- 从GL渲染切回正常渲染，会播放失败（即使刷新Surface，也被GL绑定，依赖解决）
播放框架 - GLVideoRenderer
OpenGL 从零开始写一个Android平台下的全景视频播放器
TextureView+SurfaceTexture+OpenGL ES来播放视频
存在问题：
1、视频这边 setRenderer 后没有触发 WallpaperGLThread 的 onDrawFrame，图片可以（已经解决）
2、视频播放会不停的闪烁（已经解决）
3、视频播放图像颠倒（已经解决）
4、视频播放会卡住渲染线程（已经解决）

问题2：
因为GL刷新频率超过帧率，有时候调用了 onDrawFrame，但是没有画图，但是 gl 不知道，还在 swap，就显示老的画面了，导致画面抖动。

存在问题：
1、切换比例时，会闪烁（已经解决）
备注1：
比例调整时，原因未知，但是如果不调整Surface大小，只调整glViewPort，是不会闪烁的。
