DirectShow Interface

Note

DirectShow can only be used in combination with the Microsoft Windows operating system

.

Since Windows Vista,

Movie Maker

does not support capturing from a device registered for DirectShow

anymore.

This is the documentation of the MATRIX VISION DirectShow_acquire interface. A MATRIX VISION specific prop-
erty interface based on the IKsPropertySet has been added. All other features are related to standard DirectShow
programming.
