Driver parameters:
~~~~~~~~~~~~~~~~~~
You can use some additional parameters during module loading:
Example:
modprobe radeon_vid swap_fourcc=1
List of driver's parameters:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
mtrr=1/0 configures MTRR (if available) default = 1
swap_fourcc=1/0 performs byte swapping of passed fourcc.
(It's required for compatibility with -vo mga)
To know more about driver's parameters execute:
modinfo radeon_vid
or
modinfo rage128_vid
Note:
~~~~~
For command line of mplayer:
You can pass only options with can be recognized by vo_vesa driver.
(Indeed radeon_vid and rage128_vid are stupid things and can create
video overlay only. But mode switching and other adjustement performs

This stuff (radeon(rage128)_vid) currently doesn't support any standards.
So after implementing linux standards I'll fully rewrite this driver.
Enjoy
Full example:
~~~~~~~~~~~~~
modprobe radeon_vid mtrr=1
echo "deinterlace_pattern=F0055555">>/dev/radeon_vid
mplayer -vo vesa:lvo:/dev/radeon_vid -fs -zoom -bpp 32 filename
