Thanks for your reply. Unfortunately, it did not help. Based on your suggestions I tried the following:

Install V4L2:

sudo add-apt-repository "deb http://ubuntu.mirror.cambrium.nl/ubuntu/ `lsb_release -cs` main universe"
sudo apt-get update
sudo apt-get install gem-plugin-v4l2

Than, I copied mwlinuxvideoimaq.so from the toolbox folder:

/root/Documents/MATLAB/SupportPackages/R2016a/toolbox/imaq/supportpackages/genericvideo/adaptor/glnxa64

After, I removed all files in that folder and placed back mwlinuxvideoimaq.so, I rebooted Matlab.

>> checked if it worked (still didn't).

Last, I reinstalled OS Generic Video using supportPackageInstaller and rebooted the computer.

>> checked if it worked (still didn't).

Forgot to mention last time, but all other programs that use a webcam work as expected on the computer (e.g., cheese, etc.).

Hi,

I have the exact same issue, did you find a solution?

Unfortunately, it seems to be a problem that remains unsolved by the community. I 'solved' it by switching to Windows OS.
