How can I solve a VideoReader error on ubuntu linux?

I am using Matlab 2017a on ubuntu linux 16 to read a video (mp4) but the VideoReader function gives me an error

Error using VideoReader/init (line 607) The filename specified was not found in the MATLAB path.

Error in VideoReader (line 172) obj.init(fileName);

the code I am using is:

 secuence=VideoReader('completePath/vigi_prueba');

I read it could be a problem with gstreamer, when I run the command dpkg -l | grep gstreamer on the console I get answers for both gstreamer 1.0 and 0.10 installed

Thank you

Can you test to see if your filename can be found from Matlab using the "exist" function?

[Nicolas Cuellar]

thanks for the quick answer. when I use the exist function it shows:

 exist('/completePath/vigi_prueba')

ans =

     2

And I am pretty sure the file is there, actually if I use the command

 dir('/completePath/')

it shows :

. .. vigi_prueba

Is there a problem finding the file?
