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.

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:



Video Decoder

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.

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.
