Hi,
I am using SDK VISION_03_03_00_00. I used your example of vip_single_cam_openvx where I modified your openvx.c to run vxColorConvertNode,vxChannelExtractNode and vxCannyEdgeDetectorNode. Also I am using Windows OS.
Here is my code.

When i i execute this code i got message
VX_ZONE_ERROR:[vxVerifyGraph:682] Node kernel Validate failed VX_ZONE_ERROR:[vxVerifyGraph:766] Graph verify failed Assertion @ Line: 275 in openvx/openvx.c: VX_SUCCESS == vxStatus : failed !!! Assertion @ Line: 275 in openvx/openvx.c: VX_SUCCESS == vxStatus : failed !!!
Can you help me to find what is causing this problem?
