webcam apps
==webcamoid==
is default in synaptic, maar voor install latest version via .dep install
webcamoid kan ook recording van screen nemen ?
guvcview
terminal : cvlc v4l2:///dev/video0
vlc opens with the webcam active
close terminal with ctrl + C
or use cvlc v4l2:///dev/video0 & disown
( v4l2 == video 4 linux api and drivers sub system )
guvcview works the best for me,
nice settings,
works good on my 6 year old 64bit desktop PC, works better if your PC has at least 16 gigs of ram(memory) , and a hard drive thats 500 Gigs or bigger,
“webcamoid” is for newer pc’s , is ok, but works better if machine has a decent video and graphics card,
I use Mint Mate 19.1 and of the top 6 I tried, Webcamoid works by far the best. Latency is minimal, if at all; of course your cam hardware is going to dictate much of that. Using an HP Compaq 6000 all in one with built in webcam, I get excellent results. Whereas with Cheese, the latency/stutter is intolerable.
