Member Function Documentation

void scanner::VideoKernel::check_frame ( const DeviceHandle &  device, const Element &  element  )

protected

Checks frame info column against cached data.

This function should be called at the top of the execute function on the frame info column. If the frame info changes, e.g. the kernel is processing a new video, then this calls new_frame_info which you can override.
