  • Can a USB camera drive a display directly with no X/Wayland GUI?

    From Chris Green@cl@isbd.net to comp.sys.raspberry-pi on Sun Jul 20 12:01:34 2025
    From Newsgroup: comp.sys.raspberry-pi

    As per the subject I want to use a USB camera with a SA15 Pi and have
    it drive a display (HDMI presumably) directly. The Pi I'm aiming to
    use just has the Lite version of the OS so there's no desktop/GUI
    available, just the command line.

    Is this possible?

    SA15 Pi? I haven't heard of that one.

    :-) it was an inadvertent paste that I didn't notice!

    Mplayer supports output to fbdev, which should work for that if
    HDMI works for displaying the Linux terminal command line over
    HDMI on your "SA15 Pi":

    I'm not sure about Ffplay, the man page only describes using fbdev
    for input, not output.
