<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I’m trying to build the theora source code using
Visual Studio 2005. I’m running into some problems that I’d like to
ask if anyone else has encountered and successfully defeated.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>First, I’ve managed to successfully build libOOTheora
and libtheora by finding and building all the libraries they depend on. Now I’m
trying to build the decoder filter, dsfTheoraDecoder.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>First question. In theoradecoderdllstuff.h there are two
include files, streams.h and pullpin.h that aren’t in standard Visual
Studio 2005. I have included Samples\Multimedia\DirectShow\BaseClasses from the
SDK for those include files. Are those the correct versions of the files to
include?<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Second question. Having done them I’m down strictly to
linker errors. The project comes with a reference to strmbasd.lib, a library I
can’t find in Visual Studio 2005 or the SDK. Is there another library I
should replace it with? If I remove that library reference I’m left with
two unresolved externals, DllCanUnloadNow and DllGetClassObject. These don’t
seem like the kind of entry points that just would get forgotten, so either the
library strmbasd.lib is required and contains the missing entry points or I
need to build the project differently. I’m not sure which it is and would
love any assistance you can provide so that I can get the decoder building.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Last question. It appears from testing that the theora
decoder makes a fairly slow pass through the entire file when first preparing a
file for playback. We’re looking at trying to play back video on a device
for which this initial time sink is unacceptable. Is that pass through the file
required or something that could be removed for a more streamlined version of
the decoder?<o:p></o:p></span></font></p>
