I'm trying to run an old Matlab file which uses the function 'aviread'. I searched for the function in File Exchange but could not find it. I tried to use VideoReader instead of aviread. But it doesn't seem to have the the property 'cdata'.

Which version have you ?
aviread have been deprecated bfor releases before being removed completelly in the R2014b release. You have to use VideoReader function instead

You will need to downgrade your MATLAB to about r2012a to duplicate the functionality of aviread.
We suggest that you consider modifying the code to use VideoReader and readframe, or the computer vision toolbox VideoFileReader which is designed for effecient streaming of frames.
