Problems with ippiOpticalFlowPyrLK

[chris_t]

I'm trying to use the ippiOpticalFlowPyrLK function. Somehow it isn't working and the status array is full of 10s. That warning is ippStsJPEGMarker: JPEG marker was met in the bitstream, which seems pretty odd to me. I am using the example copied straight out of the volume 2 of the IPP documentation (example 14-5: Pyramid Building and Optical Flow Calculation).

None of the functions return an error, but the status parameter in the call to ippiOpticalFlowPyrLK indicates that something's going wrong.

Does anybody have experience with this function? By the way, I am still using version 6.0 of IPP.

Hello,

Actually values returned in pStatus array have nothing in common with IppStatus data type, please look at function documentation for details.

I've attached very simple sample on how to use IPP Optical Flow function for your reference.
