One can work with a virtual Video Capture Device in INTELLECT™ software package. This way assumes that INTELLECT™ operates in a test mode and consists of imitation of video stream feed to virtual Video Capture Device by playing back ready-made video recording. There are two types of virtual video capture devices in Intellect: 

  1. Virtual bench. It is designed to play back video recordings in mkv, mp4 and avi formats for which DirectShow codecs are installed in Windows OS.
  2. Virtual. It is designed to play back video recordings in internal Intellect format and files in .avi format.

Video recordings with B-frames are not supported.

Virtual Video Capture Devices do not support multistreaming. To ensure correct operation of a virtual Video Capture Device, including video displaying and archiving, disable multistreaming (see Configuration of multistream video).

It is not recommended to use LAV Splitter for playing clips in the Virtual Video Capture Device. FFDSHOW video decoder is preferable.

 If only Windows Media Player 11 (or its older versions) is installed on Windows OS to view video recordings, then it is to be updated to Windows Media Player 12 or DirectShow filters (codecs) of third-party vendors are to be in use.


Enable Desktop Experience Feature when using the virtial video capture device on Server OS and avi files.

Create and configure a virtual Video Capture Device as follows:

  1. Set the Use virtual grabber checkbox (The Settings panel of the Video subsystem section), having shut down INTELLECT™ beforehand.
  2. Set the Virtual or Virtual bench type of the video capture device depending on the type of the file that will be used for imitation of video stream feed.
  3. Specify the storage for video recording that is to be used for video signal imitation in the Basic settings tab of the selected Camera object.        

As a result video recording file from the selected folder will be played back in a loop. If you set path to a separate file not a folder, the file is played once without looping. If there are several files in the folder they are to be played back in the order set in the latest modification.

Files can also be sorted by names and time of creation while being played back. The sorting order is set by the VirtualGrabberSortMode registry parameter (see Registry keys reference guide).


The selected folder must not contain video recordings of internal INTELLECT™ format and AVI-files at the same time.

When playing files, the system sends events to the Debug window showing the playback status. There also are reactions for controlling videos playback in virtual grabber using scripts – see CAM.
