<font size="2"><font face="Arial">Hi,<br>
<br>
I just successfully created an ogv file using GraphStudio
(<a class="moz-txt-link-freetext" href="http://blog.monogram.sk/janos/tools/monogram-graphstudio/">http://blog.monogram.sk/janos/tools/monogram-graphstudio/</a>), <br>
Mike Wasson's Video Test Source
(<a class="moz-txt-link-freetext" href="http://blogs.msdn.com/mikewasson/archive/2008/04/21/video-test-source-filter.aspx">http://blogs.msdn.com/mikewasson/archive/2008/04/21/video-test-source-filter.aspx</a>),<br>
configured to output YUY2 data, and Theora Encoder 0.82.<br>
<br>
Theora Encoder should accept connections as:<br>
MEDIATYPE_Video, MEDIASUBTYPE_YUY2, FORMAT_VideoInfo2 or<br>
</font></font><font size="2"><font face="Arial">MEDIATYPE_Video,
MEDIASUBTYPE_YUY2, FORMAT_VideoInfo.<br>
<br>
You should try to build the same DirectShow graph using GraphStudio.
GraphStudio can display the media types<br>
of the pins, which is very useful.<br>
<br>
Have you tried using IGraphBuilder::Connect instead of
IFilterGraph::ConnectDirect? it doesn't require to specify a<br>
media type, and it should just work.<br>
<br>
