推荐答案
android-gpuimage库不支持视频录制，但是您可以尝试使用android-gpuimage-videorecording库.这是Android的gpu映像的分支，还提供了视频录制功能
android-gpuimage library does not support video recording but you can try using the android-gpuimage-videorecording library. It is a fork of the gpu-image for android that provides also the video recording functionality

请参阅GPUImageMovieWriter类

它应该为您提供正确的方向，以便在GPUImage之上开发自己的视频编写器.

想法是:
-
在当前屏幕表面上绘制
draw on current screen surface
切换到编码器输入表面，并在其上再次绘制上一个帧缓冲区
switch to encoder input surface and draw previous frame buffer again on it
切换回屏幕表面
