This section is about the Matrox G200/G400/G450/G550 BES (Back-End Scaler)
875
support, the mga_vid kernel driver. It's actively developed by A'rpi, and
876
it has hardware VSYNC support with triple buffering. It works on both
816

VIDIX is new technology and it's extremely possible that on your
1507
system it won't work. In this case only solution for you
1508
it's port it (mainly libdha). But there is hope that it will work on those
1509
systems where X11 does.
1513
1447
Since VIDIX requires direct hardware access you can either run it as root
1514
1448
or set the SUID bit on the <application>MPlayer</application> binary

There's a relatively new nVidia driver out there, it's known to work on Riva
1602
128, TNT and GeForce2 chipsets, also others have been reported working.

<title>LIMITATIONS</title>
1608
It's recommended to use the binary nVidia drivers for X before using this
1609
VIDIX driver, because some of the registers which need to be initialized
1610
haven't been discovered yet, so it will probably fail with the Open Source
1611
XFree86 <filename>nv.o</filename> driver.
1614
Currently only codecs capable of UYVY colorspace output
1615
can work in conjunction with this driver. Unfortunately, this excludes
1616
every single decoder from the
1617
<systemitem class="library">libavcodec</systemitem> family. This leaves
1618
us with the following usable popular codecs:
1619
<systemitem>cvid, divxds, xvid, divx4, wmv7, wmv8</systemitem> and some
1620
others. Please note that this is only
1621
a temporal inconvenience. The usage syntax is as follows:
1622
<screen>mplayer -vf format=uyvy -vc divxds <replaceable>divx3file.avi</replaceable> </screen>
1627

An unique feature of the nvidia_vid driver is its ability to display video on
1628
1537
<emphasis role="bold">plain, pure, text-only console</emphasis> - with no
1629
1538
framebuffer or X magic whatsoever. For this purpose, we'll have to use the
1630
1539
<option>cvidix</option> video output, as the following example shows:
1631
<screen>mplayer -vf format=uyvy -vc divxds -vo cvidix <replaceable>example.avi</replaceable> </screen>
1540
<screen>mplayer -vo cvidix <replaceable>example.avi</replaceable></screen>
