VNRecognizeTextRequest not able to read .mov files locally

Hi, I am trying to build a command line app that read local mov files and print the text to the terminal. When I open the file with VNImageRequestHandler(url: url), where the url is a hardcode path to my desktop file, the terminal reports CRImage Reader Detector was given zero-dimensioned image (0 x 0). Anyone can help? Thanks!
