Any board that works with VidCap should work.

We for now use the standard ACM/VCM/ICM interfaces but will be moving to
directshow.

You can not use MJPEG cards. They ouput compressed video, compressed video
is not suitable for re-compression in real time. You can capure MJPEG files
to disk and transcode if you wish to use a MJPEG board with NetShow.

I'm looking for information on the what is necessary for a capture
card to work with REX.  I understand that VFW compatible boards should
work.  My questions are

1) Is there a particular subset of VFW that is sufficient?
2) Is there a netshow/capture API, other than VFW, that would allow
   third parties to make their boards and drivers netshow compatible?
3) Is there an MJPEG-based interface for putting data from an MJPEG
   digital camera into Netshow?

Thanks,
 Pete
