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 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>** DO NOT USE gcc 2.96 !!! **

No. There are issues with those, either. :( Use 2.95.x series, those are reliable,

...but you don't have the X development package installed. Or not
|
|
correctly. It's called XFree86-devel* under RedHat, and xlib6g-dev* under
|
|
Debian. Also check if the /usr/X11 symlink exists (this can be a problem on
|
|
Mandrake systems). It can be created with the<BR>
|
|
<CODE>$ ln -sf /usr/X11R6 /usr/X11</CODE><BR>

./configure autodetects your DGA driver. If -vo help doesn't show

DGA, then there's a problem with your X installation.

Try ./configure --enable-dga (and RTFM)

Alternatively, try SDL's DGA driver with '-vo sdl:dga' options.

What are you doing on Linux? Can't you install a library? Why do
|
|
we get these questions? It's not <B>MPlayer</B> specific at all! Add
|
|
/usr/local/lib to <B>/etc/ld.so.conf</B> and run <B>ldconfig</B> .
|
|
Or install it to /usr/lib , because if you can't solve the /usr/local
|
|
problem, you are careless enough to do such things.

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!

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?

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>

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

can be accessed by more people than only you because they can gain root

privilegies through suid root mplayer!!!<BR>

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.

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.
