Finally, I have a webcam which isn’t locked to perpetual-320px.
An improvement to say the least. There are some troubles regarding massive lag issues when I’m recording in 1920×1080, but that’s only because I’m using the onboard graphics unit on my PC instead of the external ASUS graphics card. Irritatingly enough, the latter has been having issues with Manjaro, hence it’s not in use. I’m sure, however, that I’ll find a workaround in time.
Thanks to the lads who donated for allowing me this upgrade. Twenty pounds well-spent.
