I have a clean installation of Ubuntu 11.04 64bit and Matlab 2011a 64bit. I also have a Logitech webcam that works properly in 'Cheese Webcam Booth'. But when I execute imaqhwinfo the list of InstalledAdapters is empty.
Does anyone know how solve this?
>> imaqhwinfo
ans =
InstalledAdaptors: {}
MATLABVersion: '7.12 (R2011a)'
ToolboxName: 'Image Acquisition Toolbox'
ToolboxVersion: '4.1 (R2011a)'
I installed video4linux without any success:
$ sudo apt-get install libv4l-dev
And I also tried to register linuxvideo manually:
>> imaqregister('/usr/local/MATLAB/R2011a/toolbox/imaq/imaqadaptors/glnxa64/
mwlinuxvideoimaq.so')
ans =
Empty cell array: 0-by-1

in 14a you also have to run the supportPackageInstaller in order to install further adaptors, e.g. OS generic video

Hi,
Image Acquisition Toolbox requires Video 4 Linux 2. It looks like your have installed V4L1:

Bram,
This is an issue that we've recently discovered with Ubuntu 11.04 that we're still investigating. For now, the easiest thing is probably to move the files other than mwlinuxvideoimaq.so out of the toolbox/imaq/imaqadaptors/glnxa64 directory and then restart MATLAB.
