Why do I get a "Movie cdata must be of type uint8 array" error when I use the MOVIE command with a 16-bit grayscale AVI in MATLAB R14?

Question

MathWorks Support Team on 27 Jun 2009

I have a 16-bit grayscale AVI, filename.avi, as verified with the AVIINFO function, which returns the following info:

ImageType: 'grayscale'

I then enter the following commands:

move=aviread('filename.avi');
movie(mov)

and I obtain the following error:

 ??? Error using ==> movie
 Movie cdata must be of type uint8 array.

This bug has been fixed in Release 2007b (R2007b). For previous product releases, read below for any possible workarounds:

The MOVIE function does not accept movie objects that have the CDATA field of type UINT16.

As a workaround on a Windows machine, use the following command to view a movie, in the default AVI player:

winopen('filename.avi')
