[MPlayer-dev-eng] mplayer can't run under arm's framebuffer

[Arpi]

Hi,

you'll probably have to write your own vo driver for your arm platform.
i worked with arm-based embedded platforms recently, and the framebuffer
driver in linux kernel does not implement (or even worse: seems to
be implemented but actually ignored) some functions, including the
resolution and color space settings. these are hardwired in arm
platforms and cannot be changed from userspace programs (on some
hardware not even from kernel parameters), thus mplayer is confused.

i wrote minimalist driver which only queries the current mode and
forces color space conversion to that mode, it worked.
(but it's for mplayer g3)
