There are two versions of directshow. The first (DirectShow) is dependent on
directsound and the second (DirectShow2) is not. However there is an issue
with some PSDK versions and hanging include which needs to be commented out
in the code. There is a message in the code saying "if you get this error go
comment out..". DirectShow2 also has support for camera controls and
detection of non webcam directshow devices like video devices which accept
RTSP type commands (still WIP).
I find the directsound implementation troublesome. I use WMM with large
number of buffers (10 for vista/win7).

I am sorry, I really do not have time right now to pursue this issue.
I do know the direct sound is an unutterable mess, mostly due to Microsoft
constantly changing the location of libraries and header files. There are
also two versions of it in the source tree and I have no idea what the
difference is between them, other than significantly different code!
What we really need is someone to take over the care and feeding of that
sub-system. Any volunteers?
