Re: Direcshow problems with WMV9 Decoder for XP platform

From: "Kris"

Acutally I think maybe the problem is on the encoder
side. Looking at wireshark it seems the packets are not
sent very fast.

I think I know what your problem is: by default the WMV
encoder is *slow*. You should configure it to encode to a
lower quality but much faster by setting its complexity
property:

1. query the DMOWrapper for IPropertyBag
2. call IPropertyBag::Write(L"_COMPLEXITYEX"), the value is
of type VT_I4

A good value for real-time performance is 1 (I don't
remember if 0 is also valid). Higher values require faster
CPUs.

Once the encoder is configured to perform in real-time, the
buffering filter is not required, so you may want to take it
out (but you can live it there if you want to).
