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

Enjoy!
