[MPlayer-users] New tdfxfb driver

Ok, I've spent the day working on a new tdfxfb driver. This will let you do
movies in 16, 24 or 32 bpp mode. It allows the video codec to use DRI (Might be
a small bug in there). OSD is slightly fucked, maybe someone wants to have a
look at that.
I'd appreciate any testers for this, reports, good or bad and I'll try to fix
it.
I have sent several bug reports to the maintainer recently, without reply. I
guess I'll be the maintainer of this new version if he doesn't talk to me...
Unfortunatly I'm off on holiday now, so you've got a week to find all the bugs
and maybe even send me patchen!
(File attached as diff would be about twice as big!)
TODO:
- Fix OSD
- Find DRI heissenbug
- Add YUY2 and UYVY support
- Clean up the driver a bit more

/* Copyright (C) Mark Zealey, 2002, <mark at zealos.org>
*
* 30/03/02: An almost total rewrite, added DRI support and support for modes
* other than 16bpp.
*
* TODO:
* - Fix OSD (It's position is different in 16 and 32 bit mode)
* - Add YUV2 and UYVY support
* - Remove some of the old dud code

*
* Most code rewrited, move from /dev/3dfx to /dev/fb0 (kernel 2.4.?)
* add support for YUY2 and BGR16 format, remove all X11 DGA code.
* - add support for hardware accelerated OSD (buggy for now).
* work on BGR16 and YUY2 (VO_3DFX_METHOD == 2 only)
* [oct2001]
* - added hardware acceleration for OSD (does not look nice, but is faster)
* (for YV12 don't fork.)
* - fixed YV12 support for ffdivx, but on my cpu this is sllower of yuv2rgb()
* try to uncommenting '#define YV12_CONV_METH'
* - fast_memcpy() is sllower of memcpy() (why, i don't know)
