Image Acquisition Toolbox™ Support Package for OS Generic Video Interface enables you to acquire images and video from DirectShow® (Windows®), V4L2 (Linux®), QuickTime (Mac) video capture devices directly into MATLAB® and Simulink®.
This support package is functional for R2014a and beyond.
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.
I can't see all available resolutions in macOS Mojave. Did anyone solve this?
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
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.
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?
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 ?
There was an installation issue that we had fixed. Given you are still having download issues, can you please try the instructions from the following link:
If you still run into issues, we would need more information for which it would be best to contact technical support.
i can't download it can anyone help me out???
I can´t install it! Can someone help me?
Indeed it works well and supports different kinds of cameras.
It seems like the Image Acquisition Toolbox has not been properly installed. Can you reinstall MATLAB and Image Acquisition Toolbox before installing the Support Package.
I am getting the error while installation. the error is:
There was a problem executing post-install actions for package with basecode OSVIDEO
Error using eval
Undefined function or variable 'imaqreset'.
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.
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.
I am using using Matlab R2014a , macvideo and OS X Yosemite
it works very well
I have a problem with the installation
can any one help me??
I need it asap.
MacOS User need download and install USB Webcams ! but not Generic Video Interface !
Its download link of USB Webcams for all platform：
not able to download this package. Error says "There was a problem downloading the support package".
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.
Thank you in advance. my company firewall block the download link. May I ask whether there is any other download link ?
i am unable to download this package
Hi .i can not install or DL this package.
I can not use it to open the camera on the OS Ubuntu
I am not able to download this. There was a problem downloading the support package. To resolve this issue, see this MATLAB Answer.
Already tried all options anything else I can do. Please help as soon as possible
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.
or the feature is not recognised.
This will be fixed in a future release, but for now, you can use this:

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.
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
Thanks for replying, I am running 16b. What tests can I run?
Peter - macvideo support has been updated to AVFoundation as well in R2016b.
Is it possible for you to upgrade to R2016b?
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.
Just drag and drop the file in the command window and hit enter, the installation would begin!
