IAMVideoControl Interface

Windows Mobile 6.5
A version of this page is also available for

This interface enables you to flip a picture horizontally and/or vertically, set up a stream so it can capture from an external trigger (such as a camera button that the user pushes), simulate an external trigger in software, and list the available frame rates.

Use this interface when your application runs on hardware that is capable of flipping and external triggering.

In addition to the methods inherited from IUnknown, this interface exposes the following methods.

Method Description


Retrieves the capabilities of the underlying hardware.


Retrieves the actual frame rate at which the device is streaming. This method is used with devices, such as the Universal Serial Bus (USB) or cameras that use the IEEE 1394 serial standard, where the maximum frame rate can be limited by bandwidth availability. This is only available during video streaming.


Retrieves a list of available frame rates.


Retrieves the maximum frame rate currently available based on bus bandwidth usage for connections such as USB and IEEE 1394 camera devices where the maximum frame rate can be limited by bandwidth availability.


Retrieves the video control mode of operation.


Sets the video control mode of operation.

Video capture filters automatically exposes this interface if the driver supports the PROPSETID_VIDCAP_VIDEOCONTROL property set. For more information, see Camera Drivers.
