== Summary ==
Captures Video from device using DirectShow.

== Description ==
Requires DirectShow 8.1 or higher.

If you don't want to use DirectShow use the
[[Class VLCapture.TVLCapture|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
[[Property VLDSCapture.TVLDSCapture.Enabled|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 [[Class VLAVILogger.TVLAVILogger|TVLAVILogger]],
[[Class VLImageDisplay.TVLImageDisplay|TVLImageDisplay]] or [[Class VLDSImageDisplay.TVLDSImageDisplay|TVLDSImageDisplay]].
