Long time since anyone asked for wxcam, maybe another request should be made because it does work in PCLOS.
What is in the repo and works (at least it does here) on my standard-ish up-to-date PCLOS KDE is ffmpeg on the command line.
ffmpeg -f video4linux2 -i /dev/video0 -r 30 -vcodec mpeg4 -b 1000 -qscale 5 -bt 256k -y -f alsa -i hw:0,0 -ar 44100 `date +%s`.avi
this records here with sound using alsa, not pulse audio. The usb webcam is a cheapy from amazon, does not really have a name on it only "Megapixel"
It id's as Bus 001 Device 006: ID 0ac8:3450 Z-Star Microelectronics Corp.
edit: I went back a couple of years and amazon still has the order details, (scary) listed as Kinobo 5 Megapixel USB Webcam for /some-other-distro-starting-with-U / Linux / Unix Laptop Desktop
