Using D7
ImageEN 4.3.0

Using a Samsung win8 32bit tablet. Has front/rear cameras.

Intel Imaging Signal Processor 2300

Using any of the demos for video capturing I get this error.

---------------------------
Video Capture Demo
---------------------------
Access violation at address 71B87882 in module 'AVICAP32.DLL'. Read of address 00000020.
---------------------------
OK
---------------------------

Any ideas?

If I use the DemoVC from Video Capture 3 demo, I get this error.

If I use the DShowCap from DirectShow3 demo, it works with both cameras.

VideoCaptureXX uses the old VfW (Video for Windows) API, that is no more supported by camera manufacturers. You should use only DirectShow API, as in DirectShowX examples.
