Can't run VideoReader

I am using Matlab 2016a on Mac OS system. It shows error when I use VideoReader

>> VideoReader('comp_street.avi')
Error using VideoReader/init (line 619)
Failed to initialize internal resources.
Error in VideoReader (line 172)
          obj.init(fileName);

Does anyone know how to fix this please? Thanks for help!
