Seems like FreeBSD supports the VT management API that mpv expects but with declarations in the sys/consio.h header instead of sys/vt.h.

With this patch playing videos directly on the console (when DRM/KMS is supported) works on my computer.

$ mpv -vo gpu --gpu-context=drm <video-file>

Switching VT while it's running (even if paused) unfortunately doesn't work very well (and crashes the X server if you switch to it). Still pretty neat that it does play the video though.
