Hi,

I know there are lots of posts regarding Android native camera access issues, but I think my case differ a little bit from other to post my own question... (hope i'm right :-) )

I'm trying to open a camera from a cpp code called from another library (libpd).

When I call : new cv::VideoCapture(CV_CAP_ANDROID + 0);

The app crashes, logcat *:E tells :

I'm surprised because the sample Native Activity works fine.

I'm using OpenCV4Android 2.4.6 r2 and targeting to Android 4.3 (also tried 4.1.2).

Could someone help me on this ?

Thanks ! a

I recommend you to create a ticket on code.opencv.org with full logcat log and full problem description. It looks like a bug on OpenCV size.
