Keep calling
pDSCaptureBuffer->GetCurrentPosition(&dwCapturePosition, &dwReadPosition)
When dwReadPosition has changed enough since the last processed frame that
there's a whole frame ready, lock the region from dwLastFrameReadPosition
to dwReadPosition. Never lock the entire buffer, that will halt capture
while you compress.
Copy the locked region into a buffer, update dwLastFrameReadPosition =
dwReadPosition, and unlock the buffer again.

Repeat.
If you want to avoid the rather gross ove...
