Is the SDK (or at least the parts that do not need a depth camera) supposed to work with any camera ?
I tried to execute each sample on my Lenovo X1 Ultrabook, with the integrated camera. The samples that need the depth camera returned with an error as expected ("Failed to initialize video streams"). But the others, the face detector for example, crashed as soon as it try to acquire a frame. With the debugger, I see that the initialization step runs properly and return no error and the crash occurs during the frame acquisition, in libpxccore.dll.
The same program on my other laptop runs well...
I can send a crash dump and all information you need.
