Can not open any movie file

I am trying to open movie file but it does not open. I have movies in current folder of Matlab. Every time this error comes;

"Movie destructor, delete movie object

Error using Movie (line 98)

Can't find file: 1.MOV"

I have tried to open mpg and mp4 files also. I am getting same error.

Do you have any code to post here?

[Muhammad Awais]

I have tried these codes.

cam=Movie('1.MOV');

cam=Movie('1.MOV', 'double', 'grey');

[Walter Roberson]

Please show the output of

which Movie

There is a Mathworks supplied function named movie but MATLAB is case sensitive and that would not be the same as Movie so you might perhaps be using a non-Mathworks routine.

[Muhammad Awais]

Here is the output

which Movie
C:\Users\Awais\Documents\MATLAB\Add-Ons\Toolboxes\Machine Vision Toolbox (MOOC build)\code\Movie.m  % Movie constructor

[Walter Roberson]

That appears to be Peter Corke's toolbox

http://petercorke.com/Machine_Vision_Toolbox.html

But possibly in a different edition than would be downloaded from there.

Are you specifically wanting to use that Machine Vision toolbox, or are you trying to open a movie for another use? If you have a different use then use a different routine name to open the movie.

[Muhammad Awais]

I am specifically using this toolbox, provided by Peter Corke. And I want to use this because I am doing online course and it is requirement of the course to use this toolbox.

A google search revealed various versions of the Machine Vision Toolbox. The Movie class in the most recent version on this link (posted by Walter Robertson) does not seem to contain the error you are encountering. However, the same class in this GitHub download does contain the error in the Movie constructor. If I download the toolbox from Walter Robertson's link, it works without problems and creates a Movie object. I can't get the GitHub version to work on my Matlab release (R2016b).

Unfortunately, I cannot reproduce the error using that version of the toolbox because I can't find the function "path2cell". But it seems like it fails if the video file is not in the Matlab search path (so one thing you could try is adding the directory that contains the video file to the Matlab search path). And when you add a toolbox, you should always add the folder that contains the toolbox and all of its subfolders to the search path.

What does

which('iread')

return?

If adding the current directory fails, I would suggest you download the toolbox provided in Walter Robertson's link and see if it fixes your problem. I downloaded vision-3.4.zip and Images.zip and it worked just fine.

The error message means, that the file "1.mov" does not exist in the current folder. Perhaps you have to specify the path of the file also.

[Muhammad Awais]

I have tried the path also, like this:

cam=Movie('C:\Users\Awais\Documents\MATLAB\Work\1.MOV', 'double', 'grey');

Still same error.
