I am trying to integrate GPUImage into my iPhone app to take photos with real-time filters. But I found an annoying problem: when I use the front camera to take photos, there are always some vertical black bars in the result image.

  • Rear camera never has this problem;
  • It has nothing to do with filters, I have tried without any filter.

First I think it has something to do with my iPhone hardware, then I searched on internet, other developers have met the same problem (with no solution).

    Maybe this can help you out:

    I had the same exact problem. In the GPUImageStillCamera.m, I commented out “[self captureOutput:photoOutput didOutputSampleBuffer:imageSampleBuffer fromConnection:[[photoOutput connections] objectAtIndex:0]];” and now the glitches are gone. That’s the only way I was able to fix the problem without forcing GPUImageOpenGLESContext’s +supportsFastTextureUpload to return NO.
