Summary

Captures Video from device using DirectShow.

Description

Requires DirectShow 8.1 or higher.

If you don't want to use DirectShow use the TVLCapture component instead.

DirectShow based video capture component.

Use this component to capture video data from a capturing device such as TV Tuner or Camcorder.


To capture data from a device, place the component on a form, select the driver of the device to use for capturing, set the Enabled property of the component to True, and connect the output pin to an InputPin of a component capable of receiving video data, as example a TVLAVILogger, TVLImageDisplay or TVLDSImageDisplay.
