4 months ago On a headless pi
without a "head", (video monitor) of course no video will show using kmssink framebuffer video on the Pi. You can only render audio. ????? what is your issue exactly?
use option -vs 0 for audio-only rendering on a headless system.
If kmssink is rendering video, with no attached monitor, it is probably going to /dev/null !

4 months ago If by "headless" you mean you want to use X11 forwarding to display video on a remote terminal, you need to be running X11 on the pi, so kmssink will not do this.
https://linuxconfig.org/how-to-enable-x11-forwarding-on-raspberry-pi
I suppose you could set up X11 forwarding and experiment with -vs xvimagesink or -vs ximagesink
use -vs xvimagesink
*(unfortunately ximagesink is broken on Pi for Gstreamer 1.22.0 - 1.22.9, if you need it, it needs a tiny patch to fix a missing initialization that crept in when it was upgraded to touchscreen support. Without the patch it segfaults on starting. See https://github.com/FDH2/UxPlay/wiki/patches-for-(1)-broken--videoflip-method-and-(2)-broken-ximagesink---in-GStreamer-1.22.0

4 months ago I tested X11 forwarding. Yes uxplay works: video on the ssh client (but the sound is not forwarded, and still comes from the Pi)
I also tested uxplay -vs xvimagesink so it doesnt need the ximagesink (which is patched on my system)
use just ssh <user@raspberrypi> -X uxplay
you need a Pi running X11 (not "lite") (perhaps it will work on lite if you install X11)
On a headless pi the kmssink option goes through fine yet no video is displayed
