Android Native Camera Focus Mode With 2.4.3 & Samsung Galaxy S2

edit

Hi, I'm starting to use the native camera through ndk (c++) with the android, and whatever I set the focus mode to doesn't seem to work...

I can see the parameters patch has been added to cap_android.cpp (line 299+) but I cannot see any difference in the focus after applying the property. The code I am using is:

cv::VideoCapture capture(CV_CAP_ANDROID + 0);

capture.set(CV_CAP_PROP_ANDROID_FOCUS_MODE, CV_CAP_ANDROID_FOCUS_MODE_AUTO); capture.set(CV_CAP_PROP_ANDROID_FLASH_MODE, CV_CAP_ANDROID_FLASH_MODE_TORCH);

Which must be working, as I have the flash light coming on.

Btw, I'm using a Samsung S2 and android 4.0.3.

Any pointers to how I can get this to work? Am I doing something wrong?

Also, whenever I set the properties, it resets the camera capture, is this normal?

Thanks in advance.
