Video driver for SVGAlib
|
|
by Zoltan Mark Vician <se7en@sch.bme.hu>
|
|
Code started: Mon Apr 1 23:25:47 2001
|
|
Some changes by Matan Ziv-Av <matan@svgalib.org>
|
|
Compleat rewrite by Ivan Kalvachev 19 Mar 2003:
|
|
|
|
Wrangings:
|
|
- 1bpp doesn't work right for me with '-double' and svgalib 1.4.3,
|
|
but works OK with svgalib 1.9.17
|
|
- The HW acceleration is not tested - svgalibs supports few chipsets,
|
|
and i don't have any of them. If it works for you then let me know.
|
|
I will remove this warning after confirm its status.
|
|
- retrace sync works only in doublebuffer mode.
|
|
- the retrace sync may slow down decoding a lot - mplayer is blocked while
|
|
waiting for retrace
|
|
- denoise3d fails to find common colorspace, use -vf denoise3d,scale
|
|
|
|
TODO:
|
|
- let choose_best_mode take aspect into account
|
|
- set palette from mpi->palette or mpi->plane[1]
|
|
- make faster OSD black bars clear - need some OSD changes
|
|
- Make nicer CONFIG parsing
|
|
- change video mode logical width to match img->stride[0] - for HW only
