vo_ggi.c - General Graphics Interface (GGI) Renderer for MPlayer
|
|
|
|
(C) Alex Beregszaszi
|
|
|
|
Uses libGGI - http://www.ggi-project.org/
|
|
|
|
TODO:
|
|
* check on many devices
|
|
* implement gamma handling (VAA isn't obsoleted?)
|
|
|
|
BUGS:
|
|
* palettized playback has bad colors, probably swapped palette?
|
|
* fbdev & DR produces two downscaled images
|
|
* fbdev & FLIP (& DR) produces no image
|
|
|
|
Thanks to Andreas Beck for his patches.
|
|
|
|
Many thanks to Atmosfear, he hacked this driver to work with Planar
|
|
formats, and he fixed the RGB handling.
