In the superresolution sample (built with vc11 compiler) the the following line:

//Ptr<superresolution> superRes;

superRes->nextFrame(result);

results the following error error (tried with multipe test videos):

and if I change the optical flow method to simple, it takes forever to run (30 min with an i7 2600k)

Any idea?

Update:

The program used 3.5 GB memory before it stopped. Its simply unreasonable. Must be a memory leak.

The BTV SuperResolution algorithm was oriented for small input videos. And it use a lot of memory for inner buffers. Your video has large resolution [768 x 576] and you upscale it with factor 4. Try to reduce scale factor, temporal radius or input resolution (for example upscale only a part of frame).
