[SOLVED] my guvcview records "frozen" video

Post by ddaupert » Sat Mar 03, 2018 11:30 am

I need to record quite a number of video/audio clips for a project. I've run across posts about guvcview that look very promising, except it does not record video on my equipment. I get audio nicely, but the video file shows only a static image, just like a photo. I CAN record using cheese, so I know the webcam, driver, etc. work, but that app is not optimal.

I installed guvcview version 2.0.2 from the repos using Synaptic Package Manager. I also installed QT V4L2 Test Bench, which tells me (among other things) the webcam driver is uvcvideo.

I'd very much appreciate help with figuring out how to get this working. Please let me know if any other info is needed, or any other useful troubleshooting steps I can make.

Here are some specs:

Hi ddaupert,

IMHO "guvcview" is one of the very best webcam software packages, but the one from the software repositories has never worked as well for me as the one from their PPA.

Assuming you installed the 3rd party multimedia stuff when asked during the installation of Linux Mint (mint-meta-codecs), have you also installed "ubuntu-restricted-extras", video for linux (v4l) packages, from the Software Manager or Synaptic Package Manager (SPM)? If not, I recommend doing that.

Install "guvcview" webcam and V4L software and try it.

To install this using the PPA method, open a console terminal, type in, or copy & paste, each line below one by one:

Code: Select all

sudo add-apt-repository ppa:pj-assis/testing

Code: Select all

sudo apt-get update

Code: Select all

sudo apt-get install guvcview

Hope this helps ...

Hello Phd21 --

That was the fix. I removed the install by Synaptic, installed using your suggested commands, and the PPA version does record video. BIG THANKS!

Hi ddaupert,

You are very welcome...

"Guvcview" can record video and audio whereas a lot of webcam software only does video.
