videoInput seg fault

I am developing a project using openframeworks. The original project was in v061, so I went with it. But I’d need to migrate to higher version since some other libraries I need don’t support v061. But then I have a problem about the project that was successfully running using v061, it couldn’t run in any higher version from v062. Compilation is finished with no error though, the .exe stops working every time.

I tried to debug the program, a segmentation fault message SIGSEGV showed up, and the callstack has the following information when it steps to ofVideoGrabber::initGrabber(), which calls videoInput::setIdealFramerate():

#0 00000000 0x00481b1d in videoInput::setIdealFramerate() (??:??)

Any suggestions?

Thank you,
