Hi Doug, The UCL version of vic already supports V4l2 see: https://mediatools.cs.ucl.ac.uk/mbone/mmedia/wiki/VicDownload https://mediatools.cs.ucl.ac.uk/mbone/mmedia/browser/vic/trunk/video/grabber-v4l2.cpp
There are still a number of drivers in the kernel (including some for webcams) that are still video4linux version one only - Now all video capture devices are listed as /dev/video - one has to open the devices and see which ones can be opened with V4L1 or V4L2 - thus the UCL version compiles both drivers. We are in the process having the AG features ported into the UCL version of vic - either by ANL or by UCL, we also plan to integrate work from NCHC vic - under our SUMOVER project - as mentioned by me at the recent AG retreat. We would welcome any developer work on vic - we are keen to bring on board any active developers and potentially provide commit access to the SVN repository.
