Webcams and Building software

[Patton Echols]

I'm still working on my new webcam.  Finally have it running with the 
uvc driver and W4L2  It seems that the problem is that much of the 
application software works with W4L and not W4L2. (Ubuntu Feisty, the 
cam worked - I just could not tell!!!)

Questions:

Does anyone know of a good application that will allow the recording of 
video, with sound, snapshots, otherwise controlling the cam that is W4L2 
compliant?

Is anyone familiar with wxCam?

I intend to give wxCam a try, but here are my compile issues:

The dependencies include:

1. wxWidgets version 2.6 or 2.8  Both appear to  be in the 
repositories.  Anyone know what of the many pieces and parts need to be 
installed?

2. GTK+ version 2.2.x .  No surprise, the version of GTK+ in the 
repositories is 2.0.x.  If I track down and install the 2.2 version, do 
I need to uninstall the version from the repositories first?  Or 
"upgrade". Is this risky? How would I go back if I needed to? 

Any thought anyone can share greatly appreciated.
