New video output technique Linux Video Overlay:

Browse Source 
-vo vesa:lvo:drv_name
    (for example -vo vesa:lvo:/dev/radeon_vid or -vo vesa:lvo:/dev/mga_vid)

Note: You don't need to have graphics screen before loading xxx_vid driver
vo_vesa will switch to graphics mode before using of xxx_vid driver.
So you can traditional start it from text-mode.
