well, so it is about the DRI MGA 400 driver !

here is a little FAQ chapter outta xmame.xgl ..:

<http://x.mame.net/xmame-doc-4.html#ss4.2>
A: We have the following experiences (date 20010713):

    * Vodoo3 + DRI OpenGL driver (XFree86 4.0.2), with command line options "-noglaa" and 16bpp X11 server color depth.
    * Vodoo1 + Mesa 3.4 + Glide, with command line options "-glres 640x480"!
    * GeForce + NVIDIA OpenGL driver + XFree86 4.0.2 with default command line options and 16/24bpp X11 server color depth.
    * NVIDIA TNT2 + NVIDIA OpenGL driver + XFree86 4.0.2 with command line options "-bpp 16" and 16bpp (may be 24bpp also ???) X11 server color depth (OpenGL colortable mapping is buggy).
    * NVIDIA TNT + NVIDIA OpenGL driver + XFree86 4.0.2 with command line options "-bpp 16" and 16bpp (may be 24bpp also ???) X11 server color depth (OpenGL colortable mapping is buggy).
    * Matrox MGA 400 + DRI OpenGL driver (XFree86 4.0.2) with command line options "-bpp 16", "-noglaa" (???) and 16bpp (may be 24bpp also ???) X11 server color depth (OpenGL colortable mapping is buggy).
    * ATI R128 + DRI OpenGL driver (XFree86 4.1.0) with command line options "-noglext78 -noglaa" or "-bpp 16 -noglaa", where the latter options are a bit slower (about 5 fps).
    * LinuxPPC - Powerbook-Firewire + ATI R128: see above!
</http://x.mame.net/xmame-doc-4.html#ss4.2>

the problem with "-vo gl" is, that IMHO, it is not compliant with OpenGL specs,
i guess, e.g. you "just" update the texture, no "redisplay".

so, is there a patch or solution for the "old" matrox cards,
which can be added to gl2  ?

but i guess it is not necessary, for the near future more cards will work well
with the gl2 driver, as for SGI machines etc.

of course ;-), Xv is more appropriate vor video solution ;-)

but if somebody wants to add mplayer to its 3d environment,
well, gl2 may be suitable.

cheers, sven
