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). The JavaScript equivalent is MediaDevices.getUserMedia()
.
Object Creation: roVideoInput is created with no parameters:
CreateObject("roVideoInput") |
These return an array of strings describing the various inputs and video standards that the video capture device supports. The following are the possible standards that can be returned: PAL-D/K, PAL-G, PAL-H, PAL-I, PAL-D, PAL-D1, PAL-K, PAL-M, PAL-N, PAL-Nc, PAL-60, SECAM-B/G, ECAM-B, SECAM-D, SECAM-G, SECAM-H, SECAM-K, SECAM-K1, SECAM-L, SECAM-LC, SECAM-D/K, NTSC-M, NTSC-Mj, NTSC-443, NTSC-Mk, PAL-B and PAL-B1. Inputs returned are s-video and composite.
Use the above to get and set the input and video standard.
Returns the possible controls on the input. These include "Brightness," "Contrast," "Saturation," "Hue," and others.
Sets the value of the specified control.
Returns an associative array with 3 members: "Value," "Minimum," and "Maximum." "Value" is the current value, and the possible range is specified by "Minimum" and "Maximum."
This script uses the HDMI Input as the video source to create a full-screen display.
