MV Frame Access DirectShow Filter
The MontiVision Frame Access filter
provides direct access to the frame buffer of the DV video
stream. It therefore uses a callback interface.
Applications implement the interface and deliver a pointer to the
interface to the MV Frame Access filter. The ProcessFrame(...)
method of the callback interface is called by the filter
for every processed video frame. This filter is the optimal
solution if you are planning to integrate hardware
independent video processing functionality into an
existing application that needs to access the image data. There are
two different callback interfaces available, IMVFrameAccessCallbackVB is
designed for Visual Basic applications and IMVFrameAccessCallbackC for
C/C++ applications. The IMVFrameAccessCallbackC interface provides
much more performance, because the image frame is accessed using
pointers, whereas the Visual Basic style interface uses the
SafeArray type.
