Hello,
The SDL's pkg-message says we can use video driver in tty terminal.
To do this you have to load the vesa kernel module or enable it in your
kernel, and set environment variable "SDL_VIDEODRIVER=vgl".
I tried it with mplayer :
$ SDL_VIDEODRIVER=vgl; export SDL_VIDEODRIVER
$ mplayer -vo sdl<the file here>
[...]
[VO_SDL] Set_fullmode: SDL_SetVideoMode failed: Unable to switch to
requested mode.
IIRC, vgl(3) mode setting unlike vidcontrol(8) doesn't work as regular user.
Try running mplayer under root, e.g.
$ sudo mplayer -msgmodule -msglevel vo=9 -vo sdl<the file here>

In case your keymap doesn't work under vo_sdl(vgl) try below workaround

Hi it works fine except after leaving mplayer or any SDL application my
tty seems broken. I can't switch to a tty anymore my screen stays black
and I must reboot/shutdown (no panic)
Are you encountering the same issue? There is no way to use vgl as
regular user or we could open a PR for it?
Cheers,
