You cannot set the 'ErrorHandler' property of FrameReade​rMessageHa​ndler.

What is wrong here? I did not understand the error. I have attached the code and error message.

Based on my understanding, you want to get the number of frames by using property NumberOfFrames. As this is property is depreciated from MATLAB 2015b. You can try another work around like:

    vidFile = '20180720_1505.avi';
    vid = VideoReader(vidFile);
    numFrames = ceil(vid.FrameRate*vid.Duration);
