[AG-TECH] Hi-quality video

[Jay Beavers]

I'll be happy to supply you with whatever direct assistance you need
with using the DirectShow APIs.  Not only does this abstract the details
of VfW and WDM drivers, it provides you a nice clean sample through the
IMediaSample interface.  To see how to do this easily, I'd recommend
going through the NullNull sample that comes with the DirectShow SDK
which simply passes the IMediaSample to you and does nothing with it.

 

In addition to being able to get the raw media frames, you also get the
advantage of having all your capture and render work done for you.  The
renderer under Windows XP is extremely advanced with built-in support
for hardware acceleration from a ton of video cards and very interesting
features such as ability to draw into a DirectX surface of your
choosing, ability to do alpha blending, windowless rendering, blending
of video streams, etc.

 

 

If you decide you want to work at a lower level than the DirectShow
APIs, I'll be happy to set up a conversation with our Device Driver
Development Kit support guys.  They should be able to help you demystify
any issues you're running into.

Yup. I've looked thru the samples in the past, and found them to be not
immediately useful for what I want to do (get the raw bits of video
frames into my app).
