Video processing with GPUImage Android

I want to use GPUImage Android to process video in real time. I see example that creating pictures with different filters but I didnt find any example of recording video with filters. Is this possible with GPUImage Android?

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

android-gpuimage-videorecording

see the GPUImageMovieWriter class

It should point you in the right direction for developing your own video writer on top of GPUImage.

The idea is to:

• draw on current screen surface
• switch to encoder input surface and draw previous frame buffer again on it
• switch back to screen surface
