Have been testing out H264 decoding. Seems to be working on files, but now testing rtsp streams.

WIthout -c:v h264_v2l2m2m parameter this works but with that, the VIM3 resets and this is the final output:

It seems Wayland is added, but xorg is broken. Selecting any login desktop option in GDM results in being kicked out. Only the Ubuntu without xorg works. So far I have tested i3, dwm, xfce, lxde, and gnome on xorg and they all fail to log in.

[EDIT] also, I just tested disabling Wayland and the system fails to boot.

Please follow this documentation to fix the X11 desktop.
