gcc 2.96 is RedHat's UNOFFICIAL (it can be found only on RedHat sites, or
RedHat distributions) and BUGGY gcc release. gcc 2.96 is TOTALLY
unsupported by <B>MPlayer</B>, because it simply SKIPS MMX/3DNow codes, it just does
not compile it. Important: this is NOT an <B>MPlayer</B>-specific problem,
numerous other projects (DRI, avifile, etc..) have problems with this shit
too.<BR>

No. There are issues with those, either. :( Use 2.95.x series, those are reliable,
and faster than 2.96 and 3.x.x . If you really really wish to use 3.0.x , be
sure to always use the newest.

<P>But we has idegs (the word 'ideg' is described further in the FAQ). And our
idegcounters overflow again and again.</P>
<P>Unfortunately MPlayer is out of our control. It's used by lamers, Linux users
who can't even use windows, and never tried to compile a kernel. They installed
(with default options) Mandrake or RedHat or Suse, and without RTFM'ing they
send messages saying 'it doesn't work! help me! please! i'm new to the linux!
help! oh! help me!'. We can't stop them, but at least we try to force them RTFM
and to read fuckin' messages of ./configure and mplayer.</P>
<P>And you clever guys come and flame us with gcc 2.96 and binary packages.
Instead of helping users or making patches to help solve problems.</P>
<P>Half of our spare/free time is spent by answering silly mails here and
making newer tricks and checks to configure to avoid such mails.</P>
<P>And there is a balance. On one hand are you, clever guys, saying we are very
bad because we don't like buggy gcc 2.96, and at the other hand there are the
'new to linux' guys who are showing us gcc 2.96 is buggy.</P>
<P>Conclusinion: we can't be good. Half of people always will say we are bad.</P>
<P>Maybe we should close the project, make it closed source, commercial, and
provide install support for it. then we could leave current work, so
development could go faster, and we earn lots of money with it and buy a big
house, etc etc. Do you really want it? It seems.</P>

x11 driver doesn't support scaling, but XF86VidMode support is now

Make sure you have the right Modelines in your XF86Config file, and
try if the DGA driver (and SDL's DGA driver, see RTFM) works for you.

It's from Gerard Lantau's ffmpeg package (<A HREF="http://ffmpeg.sourceforge.net">http://ffmpeg.sourceforge.net</A>).
It has C language DivX ;-) and OpenDivX alpha 47 codec. Some benchmarks
showed that its DivX seems to be even faster than DirectShow codec without
preprocessing, and only a few percent slower than ProjectMayo's DivX4
decoder. It uses YV12 pixel format, so old Voodoo users can use it for YUV.
Also, open the possibility to play DivX on virtually every computer that
has a C compiler. Kinda great stuff, isn't it?
