System object: vision.DeployableVideoPlayer
Package: vision

Send multidimensional video to computer screen

Syntax

step(depVideoPlayer,I)
step(depVideoPlayer,Y,Cb,Cr)

Description

    Note:   Starting in R2016b, instead of using the step method to perform the operation defined by the System object™, you can call the object with arguments, as if it were a function. For example, y = step(obj,x) and y = obj(x) perform equivalent operations.

step(depVideoPlayer,I) displays one grayscale or truecolor RGB video frame, I, in the video player.

step(depVideoPlayer,Y,Cb,Cr) displays one frame of YCbCr 4:2:2 video in the color components Y, Cb, and Cr when you set the InputColorFormat property to YCbCr 4:2:2. The number of columns in the Cb and Cr components must be half the number of columns in the Y component.

    Note:   H specifies the System object on which to run this step method.

    The object performs an initialization the first time the step method is executed. This initialization locks nontunable properties and input specifications, such as dimensions, complexity, and data type of the input data. If you change a nontunable property or an input specification, the System object issues an error. To change nontunable properties or inputs, you must first call the release method to unlock the object.
