 vobj = vision.VideoFileReader(filename, 'ImageColorSpace', 'RGB');
 v = getsnapshot(vobj);

and then i got this message :

 Undefined function 'getsnapshot' for
 input arguments of type
 'vision.VideoFileReader'.

how to define that 'getsnapshot' for input argument of type 'vision.videofilereader'?

Use this:

v = step(vobj)

The vision.VideoFileReader object does not have a getsnapshot method. Instead, you can read the next video frame using the step method.
