The GPUVideoCamera.inputCamera can not support to set FocusMode or PointOfInterest #554

Hi guys,

I'm using the GPUImage for video testing on iTouch4 using the back camera. I'm trying to set the focus point, but the inputCamera always return NO for any FocusMode by call isFocusModeSupported, and it is the same for isFocusPointOfInterestSupported (always return NO).

I'm trying the demo project "SampleVideoFilter", and calling these method in - (void)viewDidLoad;

But at the same time, for another demo project of Apple, it can achieve the function setting the FocusPoint. Could anyone help to solve this problem?

Thank you!

The 4th gen iPod touch does not support focus.

TomCorwine,

You are right. iTouch4 can only set the ExposureMode. I'm confused.

Thank you!
