System object: vision.VideoPlayer
Package: vision

Locked status for input attributes and non-tunable properties

Syntax

TF = isLocked(H)

Description

TF = isLocked(H) returns the locked status, TF of the VideoPlayer System object.

The isLocked method returns a logical value that indicates whether input attributes and nontunable properties for the object are locked. The object performs an internal 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. After locking, the isLocked method returns a true value.
