Hi Mathias,
Are you using Mojave? This is a known bug in the product and we are working to get it fixed and released soon. Are you using R2019b?
Thank

I've the same problem as Mohamed-Ikbel Boulabiar - Ubuntu 18.04 LTS, webcam Logitech C525. After system update Matlab stopped to recognize my camera. I got:
"No devices were detected for the 'linuxvideo' adaptor. For troubleshooting device detection issues, click here." Other applications (eg. cheese) can see my webcam and work without any problem.

Hi Khajista,
What code are you running? Can you give more information to help you? Are you on a MAC? What MATLAB version is this? If it is, can you look at this bug report to get a workaround for now?

Thanks

Thanks for the update Janak.
Janak Thotakura (view profile)
Hi Steven - The development team at MathWorks is aware of this issue. We are currently working on a fix. The only workaround, for now, is to launch MATLAB from the terminal to access the webcam.
-Janak
Steven Fenton (view profile)
Shankar, the bug fix works as far as allowing you to run Matlab from Terminal, Terminal is granted access and bingo! BUT, there doesn't appear to be a way to then grant access to Matlab directly as you suggest. Matlab crashes out and nothing appears (requests) in the Security & Privacy settings to allow you to change / grant access directly.
Shankar Subramanian (view profile)
Hi Modou - Are you running Mojave? Can you actually look into this bug report for the workaround?
https://in.mathworks.com/support/bugreports/details/2067164
Please let us know if it works. There is currently a bug with our support on Mojave and will be fixed soon.
Thanks

Here is another piece of bitterness: "An image acquisition device will be used to acquire image data to perform the calibration and laser tracking. The device used will be a generic Windows® video WebCam." This is from the laser tracking tutorial.... because generic Windows video WebCams work so well with Matlab. Or rather NOT as Mathworks help has been so kind to email me, explaining that I have to buy 60 euro webcams for every student.

Add logitech: Bus 003 Device 005: ID 046d:089d Logitech, Inc. QuickCam E2500 series
What a complete joke Matlab is. Who puts out a image processing, deep learning etc. software that cannot handle a webcam feed?
john thiessen (view profile)
Exactly the same situation with a Microsoft LifeCam HD-3000. lsusb: Bus 003 Device 004: ID 045e:0810 Microsoft Corp.
Hell is the point of using Matlab in a teaching environment if none of my students webcams work?
john thiessen (view profile)
Hi Madhura,
The webcam is a Trust webcam which linux 19.01 identifies as " Bus 003 Device 002: ID 0c45:62c0 Microdia Sonix USB 2.0 Camera". I have gstreamer installed. My problem seems to be fairly typical, searching the internet. There seems to be quite a bit of frustration that Matlab cannot handle something so simple as webcams.
Madhura Suresh (view profile)
Hi John,
What camera and MATLAB version are you using? And assuming that you are on linux, what distro are you running? All the new releases use gstreamer 1.0, so its best to make sure you have the gstreamer 1.0 library set installed.
Thanks.
Madhura

I have wasted hours trying to get this to work. It can't do video from a simple webcam even though pretty much every other program on my computer works with the webcam (Cheese, Skype, Google Hangouts, etc.). I have checked the installed files, etc. that Mathworks suggested on their forums and support articles. When I write to Mathworks directly, they say that because I have a student license they won't deal with the issue. What can I say? Once I am done with this class, I am back to python.

Hi Kevin,
The green preview could be because you've selected the H.264 format, which is not supported by the toolbox currently. Can you try a different format on the camera to see if that works?

Hi Toby,
Only the highest resolution is supported in Mac currently. The Image Acquisition toolbox team is aware of this, and multiple resolutions support will be added to the 'macvideo' adaptor in a future release.
Thanks,
Janak
Toby Howison (view profile)
I can't see all available resolutions in macOS Mojave. Did anyone solve this?
Mohamed-Ikbel Boulabiar (view profile)
I'm on ubuntu 18.04 LTS, webcam "Logitech, Inc. HD Pro Webcam C920", it is accessible from everywhere in all other linux applications.
On Matlab R2018b, videoinput('linuxvideo') returns errors that no device exists, and that I need to do imaqhwinfo
"There are no devices installed for the specified ADAPTORNAME. See IMAQHWINFO."
and when I do it returns
InstalledAdaptors: {'linuxvideo'}
MATLABVersion: '9.5 (R2018b)'
ToolboxName: 'Image Acquisition Toolbox'
ToolboxVersion: '5.5 (R2018b)'
But nothing works !
When switching to root, sometimes it figures it out and launch to device but only one single time.
I've never had problems opening a webcam in any other tool or software like opencv or on browsers.
Shankar Subramanian (view profile)
Hi Mohamed,
Can you elaborate more? Does the Support Package install not work successfully? Or webcam does not get detected? Or can you not connect to the webcam? Or is it unable to stream? What webcam are you currently using? What Linux distribution it is? and What version of MATLAB is it on?
Thanks
Shankar
Mohamed-Ikbel Boulabiar (view profile)
Installed but doesn't work on linux.
How an easy task of acquiring a supported webcam not possible in Matlab ?
Why is such an easy task in ANY other tool becomes complicated in MATLAB ????? why why ?

Hi Laetitia,
The imaqmex feature to 'limitPhysicalMemoryUsage' was introduced in R2016b. For release prior (R2015a and earlier), which is your case - you have the imaqmem function available. If that is not working for you, I would suggest you to come through MathWorks Technical Support to understand more as to what you are trying to achieve so that we can help you.
Thanks
Shankar
Laetitia (view profile)
To overcome the "Unable to allocate memory for an incoming frame" problem I did imaqmex('feature','-limitPhysicalMemoryUsage',false); as mentioned. I have the following error: Error using imaqmex The IMAQMEX feature specified is invalid.

The 'macvideo' on MacOS sierra does not give all available resolutions for the camera I am using. Is there a way to unlock the other resolutions, or do I need a different driver? I am currently able to view 1920x1080 but the full resolution is 4208x3120. The resolutions are available when using 'winvideo' add-on with Matlab on a PC. I have tried 3 other cameras and the full resolution list does not appear for either. I have used a 5MP, 8MP and 13MP camera.

Hi Madhura,
Thanks for the prompt reply, this fixed the problem I was having, although it should be noted that a the command needs an added - i.e.
imaqmex('feature','-limitPhysicalMemoryUsage', false);
or the feature is not recognised.
Thank you
Callum
Madhura Suresh (view profile)
Hi Callum,
This will be fixed in a future release, but for now, you can use this:
imaqreset;
imaqmex('feature','limitPhysicalMemoryUsage', false);
% create videoinput object as usual.

Same again. R2016b, latest Sierra. No luck on any macvideo (AVFoundation) camera. Just the white with a red cross for a preview (along with a status of dropped frames). Trying to start a capture results in the message "Unable to allocate memory for an incoming frame". Matlab Webcam hardware support package does work however.
ysz (view profile)
I report the same. I'm running R2016b. macOS 10.12.1 (Sierra)
I tried re-install support package but still. Both USB microsoft lifecam vx-800 and built-in camera doesn't work on latests MacBook Air
Peter Corke (view profile)
Thanks for replying, I am running 16b. What tests can I run?
Shankar Subramanian (view profile)
Peter - macvideo support has been updated to AVFoundation as well in R2016b.
https://www.mathworks.com/help/imaq/release-notes.html
Is it possible for you to upgrade to R2016b?
Peter Corke (view profile)
I'm having problems with MacOS Sierra, during preview the camera becomes active (LED on) but then no frames are acquired and the preview is a white window with a cross in it. This might be linked to the end of quicktime framework in Sierra and its replacement by AVFoundation.
