### VCAI_GETIMAGESCALE (6Ch) - Remarks

This IOCtl captures one single video image per call. To perform streaming ( continuous, multiple image capturing), use the stream programming interface to create a stream and record from the video capture device.

Note: Most video device drivers do not support all the transposition and scaling possibilities supported with this IOCtl. Consult the specific device driver's documentation for limitations, or use VCAI_GETDEVINFO to determine its capabilities.
