I have the same problem, namely that guvcview loads, then quits immediately in Linux Lite 3.8. It works fine on Linux Lite 2.6, which I have on another hard drive.
Additional info in last two hours: I uninstalled guvcview and installed Cheese instead. It shows exactly the same problem, namely the Cheese screen pops up ~very~ briefly, then immediately closes.
Further info: I ran guvcview in the terminal window on LL 3.8, then I powered down, disconnected the 3.8 hard drive and connected the LL 2.6 drive instead. Then I ran guvcview again in the terminal window (on LL 2.6) and the results are very different.
I found that the guvcview in 2.6 is version 1.7.1, whereas in 3.8 it is version 2.0.2.
I captured the terminal output in both cases. Here is the terminal output from guvcview in LL 3.8. The output from 2.6 follows beneath.
And here is guvcview in 2.6:
So I have to wonder whether guvcview 2.0.2 is simply not compatible with LL 3.8?
Is it possible to install the older guvcview 1.7.1 in Linux Lite 3.8? If so, how do I do it? (I'm almost a total novice when it comes to Linux.)
