-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
