oVideoInput()
roVideoInput supports playing back video supplied by a video capture dongle.
roVideoInput is created with no parameters:
• CreateObject("roVideoInput ")
The ifVideoInput interface provides:
• GetStandards() As roArray(String)
• GetInputs() As roArray(String)
o These return an array of strings describing the various inputs and video standards that the video
capture device supports. Standards returned are 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.
• SetStandard(As String) As Boolean
• GetCurrentStandard() As String
• SetInput(As String) As Boolean
• GetCurrentInput() As String
o Use the above to get and set the input and video standard.
• GetControls() As roArray(String)
o Returns the possible controls on the input. These include ‘Brightness’, ‘Contrast’,
‘Saturation’, ‘Hue’, and others.
• SetControlValue(control_name As String, value As Integer) As Boolean
o Sets the value of the specified control
• GetCurrentControlValue(control_name As String) As roAssociativeArray
o 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.
Here is an example script that creates a full screen display with the video capture dongle as the video
source.
v=CreateObject("roVideoPlayer")
i=CreateObject("roVideoInput")
p=CreateObject("roMessagePort")
vm=CreateObject("roVideoMode")
vm.SetMode("1280x720x60p")
r = CreateObject("roRectangle", 0, 0, 1280, 720)
v.SetRectangle(r)
i.SetInput("s-video")
i.SetStandard("ntsc-m")
v.PlayEx(i)
