smpeg segfaults too much, and can't play many streams.
(It has other shortcomings, but that does not belong here :)
smpeg only use SDL as an abstraction for the access to the
X11 window, but not to speed up the conversion.
I think software conversion is a bad thing, (obviously
because its too slow)
Profiling shows me that 33% of my 400 MHZ are used for this
conversion.(YUV -> RGB)
20 % is used by X11 (why? I already use Shared Mem for the ximages)
Its really hard to believe,that Linux has not API to
do it on the hardware.
