Hi *:
I have to ask after trying to do it in many ways, checking all kinds
of posts, searching and following guidelines.
https://trac.ffmpeg.org/wiki/Capture/Desktop
https://wiki.ubuntuusers.de/Videograbbing/
I am running:
$ uname -a
Linux niggahme 4.9.0-9-amd64 #1 SMP Debian 4.9.168-1+deb9u2
(2019-05-13) x86_64 GNU/Linux
on an "old" X130e Thinkpad which has 4 Gb of RAM.
Nothing is listed under:
# ls -l /dev/video*
ls: cannot access '/dev/video*': No such file or directory
#
As I remember, some time ago I had to do some kernel tinkering in
order to make the screen work fine on Linux:
