DirectShow-Based Video Device
Figure 5-36: Capture Source
This module allows you to select a DirectShow-based video device as a video source. Examples of Dir-
ectShow-based device are USB webcam and PCI/PCI-E capture cards (if the card vendor provides a
driver with DirectShow capture filter). In the setting dialog you can select video standard, pixel format, res-
olution (from 160x120 to 1920x1080), and frame rate (from 5fps to 60 fps).
In general, we recommend I420 or YV12 as the pixel format if your capture device supports them. But you
should also test if your capture device performs better on other pixel formats.
If you checked “Bind Module” and no video is displayed “Use Device Provided Options”. We do not re-
commend you to use this option unless it is necessary. In this case the software will no longer know the
settings and has no way to remember them.
If your computer does not have any DirectShow compatible devices or devices supported
by iN7000, the “Module Type” option will disappear. Also, some broken driver may not
implement all necessary interfaces even it is DirectShow compatible. These devices will not
show up for selection.
