Glreadpixels flip
WebUse glReadPixels to copy the data from the framebuffer to a GLubyte array. Create a CGImageRef from that data. Then create a CVPixelBuffer from the CGImageRef. Finally append the CVPixelBuffer to an AVAssetWriter. I've done a fair amount of additional research. Some people suggest copying the framebuffer and reading that piecewise with ...
