Analog Video standards

Analog video standard A video capture device exposes analog video standards when IsAnalogVideoDecoderAvailable returns true. E.g: a video capture device can expose 3 standards: "PAL", "NTSC" and "SECAM", whereas another device can expose 2 standards: "PAL" and "NTSC". So, the number of analog video standards available usually differs from a video capture device to the other.

Sample code: ... VideoGrabber.VideoDevice = VideoGrabber.VideoDeviceIndex ("ATI T200 AVStream Analog Capture (WDM)") VideoGrabber.AnalogVideoStandard = VideoGrabber.AnalogVideoStandardIndex ("PAL B") VideoGrabber.VideoSize = VideoGrabber.VideoSizeIndex ("320x240") VideoGrabber.FrameRate = 25 VideoGrabber.StartPreview

(AnalogVideoStandard is device-dependent and must be set only after selecting the current video capture device (by assigning the VideoDevice index in the VideoDevices list)

Note: any listbox that shows analog video standards of the current video capture device should be refreshed with AnalogVideoStandards (AnalogVideoStandard is the current index in this list) when the OnVideoDeviceSelected event occurs.
