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.

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.

Devices:
D. = Demuxing supported
.E = Muxing supported

DE alsa ALSA audio output
E caca caca (color ASCII art) output device
DE fbdev Linux framebuffer
D kmsgrab KMS screen capture
D lavfi Libavfilter virtual input device
DE oss OSS (Open Sound System) playback
E sdl,sdl2 SDL2 output device
DE sndio sndio audio playback
DE video4linux2,v4l2 Video4Linux2 output device
D x11grab X11 screen capture, using XCB
E xv XV (XVideo) output device

So certainly possible, with the right build options.
