Capture
ADLINK Hardware MPEG4 Device
The ADLINK Hardware MPEG4 Device Filter provides property
pages and exposes COM interfaces to control video. Hence,
an application can have two ways to control video configura-
tions: via the property pages or via the COM interfaces.
Use Property Pages
There are three embedded property pages in the driver. To
show these property pages, use Windows API: OleCreatePro-
pertyFrame.
Documentation on Displaying a Filter’s Property Page can be
found on Microsoft MSDN homepage.
The example code for adding property pages is the same as that
of the ADLINK Bt878 Video Capture.
