I followed the directions on the Theora website to download
the .ax file and the Visual Studio project to build the DLL. I then
registered the ax file using the regsvr32 tool. <br>
<br>
Then I started up the DirectShow tool called 'GraphEdit' where you can
see all the installed DirectShow filters and create the filter graphs.
In the list of all DS filters, I could find the following 3 filters: <br>
<br>
Source <br>
<br>Splitter <br>
<br>
Video Decoder <br>
<br>
The source seems the be the filter to open and read an already Theora
encoded file. The splitter seems to have only 1 input pin but I'm not
sure what this would be used for. The video decoder has 1 input and 1
output pin and would probably be for decoding a Theora encoded file to
be able to play it back in the DS video rendering filter. <br>
<br>
I'm now wondering how we would encode e.g. a webcam and microphone input with Theora as I can't seem to find an encoder.
