Class EXTProtectedContent


  • public final class EXTProtectedContent
    extends java.lang.Object
    Native bindings to the EXT_protected_content extension.

    This extension introduces the concept of protected contexts and protected resources, specifically surfaces and EGLImages. Applications can choose at creation time whether a context, surface or EGLImage is protected or not.

    A protected context is required to allow the GPU to operate on protected resources, including protected surfaces and protected EGLImages.

    An explanation of undefined behavior in this extension: Several places in this extension mention undefined behavior can result, which can include program termination. The reason for this is because one way to handle protected content is by using a protected virtual to physical memory translation layer. With this sort of solution a system may generate read or write faults when a non-protected source tries to access a protected buffer. Depending on the system these faults might be ignored or they might cause process termination. This undefined behavior should not include actually allowing a transfer of data from a protected surface to a non-protected surface.

    Requires EGL 1.4.
