Building on Mac OS 10.3 leads to several link errors.
</p></td></tr><tr class="answer"><td align="left" valign="top"><p><b>A:</b></p></td><td align="left" valign="top"><p>
The link error you're experiencing most likely looks like this:
</p><pre class="screen">
ld: Undefined symbols:
_LLCStyleInfoCheckForOpenTypeTables referenced from QuartzCore expected to be defined in ApplicationServices
_LLCStyleInfoGetUserRunFeatures referenced from QuartzCore expected to be defined in ApplicationServices
</pre><p>
This problem is the result of Apple developers using 10.4 to compile
their software and distributing the binaries to 10.3 users via
Software Update.
The undefined symbols are present in Mac OS 10.4,
but not 10.3.
One solution can be to downgrade to QuickTime 7.0.1.
Here is a better solution.
</p><p>
Get an
<a class="ulink" href="http://rapidshare.de/files/20281171/CompatFrameworks.tgz.html" target="_top">older copy of the frameworks</a>.
This will give you a compressed file that contains the QuickTime
7.0.1 Framework and a 10.3.9 QuartzCore Framework.
</p><p>
Uncompress the files somewhere that is not in your System folder.
(i.e. do not install these frameworks into your
<tt class="filename">/System/Library/Frameworks</tt>!
Using this older copy is only meant to get around link errors!)
</p><pre class="screen">gunzip &lt; CompatFrameworks.tgz | tar xvf -</pre><p>
In config.mak, you should append 
<code class="systemitem">-F/path/to/where/you/extracted</code>
to the <code class="systemitem">OPTFLAGS</code> variable.
If you use <span class="application">X-Code</span>, you can just select these
frameworks instead of the system ones.
</p><p>
The resulting <span class="application">MPlayer</span> binary will actually
use the framework that is installed on your system via dynamic links that
are resolved at run-time.
(You can verify this using <code class="systemitem">otool -l</code>).

You need a specially set up kernel to use the RTC timing code.

You have to use a video output driver that does not employ an overlay to be
able to take a screenshot. Under X11, <tt class="option">-vo x11</tt> will do, under
Windows <tt class="option">-vo directx:noaccel</tt> works.
</p><p>
Alternatively you can run <span class="application">MPlayer</span> with the
<code class="systemitem">screenshot</code> video filter
(<tt class="option">-vf screenshot</tt>), and press the <span class="keycap"><b>s</b></span>
key to grab a screenshot.

Most of them are for debug purposes, use the <tt class="option">-quiet</tt>
option to make them disappear.
You might notice that video_out CPU usage is zero (0%) for some files.
This is because it is called directly from the codec and thus cannot
be measured separately. If you wish to know the video_out speed, compare
the difference when playing the file with <tt class="option">-vo null</tt> and
your usual video output driver.
