-xy option doesn't work with x11 driver (-vo x11)

x11 driver doesn't support scaling, but XF86VidMode support is now
used: you must specify the -vm and the -fs switch, and you're done.
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 much faster. If SDL's DGA works too, use that, it'll be EVEN faster!

What exactly is this libavcodec?
</B></TD><TR><TD></TD><TD VALIGN=top>A:</TD><TD><font face="Verdana, Arial, Helvetica, sans-serif" size="2">
It's from Gerard Lantau's ffmpeg package (http://ffmpeg.sourceforge.net).
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?

<B>MPlayer</B> != avifile
The only common thing between these players is the Win32 DLL loader.
The codecs (dll) sets, syncronization, demultiplexing etc is totaly
different and shouldn't be compared.
If something works with aviplay it doesn't mean that <B>MPlayer</B> should do
it and vice versa.

then there is problem with your kernel/libc. Maybe you are using some
security patches (for example Solar Designer's OpenWall patch) which
forces loading libraries to very low addresses.
Because l3codeca.acm is a non-relocatable DLL, it must be loaded to
0x00400000, we can't change this. You should use non-patched kernel,
or use <B>MPlayer</B>'s -afm 1 option to disable using l3codeca.acm.

The KDE arts sound daemon is blocking the sound device, either wait the time
until video starts or you disable the arts-daemon in kontrollcenter.
If you want to use arts sound, specify audio output via SDL (ao=sdl), and
make sure your SDL can handle arts sound. Yet another option is to start
mplayer with artsdsp.

It works only if running as root! It's a DGA limitation.
You should become to root (su -), and try again.
Another solution is making mplayer SUID root, but its NOT RECOMMENDED!<BR>
<CODE>chown root /usr/local/bin/mplayer</CODE><BR>
<CODE>chmod 750 /usr/local/bin/mplayer</CODE><BR>

This is a *BIG* security risk! *NEVER* do this on a server or on a computer

Since 0.18pre4 we support libavcodec from the ffmpeg package. It contains
a C language DivX and OpenDivX decoder. The DivX decoder uses YV12 format
for output, thus it should work for you. Compile in libavcodec support.

Is there a hint on how to watch QuickTime and RealMedia movies in MPlayer?
</B></TD><TR><TD></TD><TD VALIGN=top>A:</TD><TD><font face="Verdana, Arial, Helvetica, sans-serif" size="2">
There's no way to do it. Therefore these formats deserve to die in flames.
Theoretically you can reverse engineer Real codecs built for Linux (they
are available as .so files), but in practice that's really difficult, even
if you know how the compiler used by Real is making assembler code.
As for QuickTime, it's possible to play some old movies and this
capability will be added to mplayer soon, but newer clips are all Sorenson
encoded, and that codec is built-in deep in the QT executable, there's
no way to use it.
