roVideoInput

This object allows playback of HDMI input or video provided by a video capture dongle. Note that the ifVideoInput

methods do not apply to HDMI input, which can be achieved by passing an unmodified roVideoInput instance to the

roVideoPlayer.PlayFile() method (see below for examples).

roVideoInput is created with no parameters:

CreateObject("roVideoInput")

Interfaces: ifVideoInput

The ifVideoInput interface provides the following:

• GetStandards() As roArray
