Hi Guo
  If you are using Visual Studio 2008, almost all libs are avaible for
DirectShow. Only the Null Output Video Sink, necessary for proper work of
Video Sampler Grabber, need some trick to work, the trick is copy the
content of the header file of Null Video to a new file and remove the COM
interfaces of DirectX9 surfaces, these interfaces need another headers that
only avaible on DirectX SDK.

You are able to find these tricks on CodeGuru site, searching for "Video
Capture"

This way saves one or two gigabytes of DirectX SDK.

> "...I indeed install directx 9.0c.so it can ..."   ::  '.so'? you are
using cygwin or something like it?

Other hint: ptbuildopts.h is generated by config application, sometimes
config.in file need some attention to see if a positive search rule is not
overlapping a negative rule. Other times you need to 'force' the config
application passing hints to it like:

--enable-ipv6   or --disable-ssh

Again, see config.in for the rules they are using.

If you manage to compile your code after some modification, dont forget to
send back to this list ;)

regards.
