"Function was not implemented" when trying to use ONI recording

Question

I'm trying to use an oni recording in my application using OpenNI. Here is my xml file:

<OpenNI>
    <Licenses>
        <!-- Add application-specific licenses here 
        <License vendor="vendor" key="key"/>
        -->
    </Licenses>
    <Log writeToConsole="false" writeToFile="false">
        <!-- 0 - Verbose, 1 - Info, 2 - Warning, 3 - Error (default) -->
        <LogLevel value="3"/>
        <Masks>
            <Mask name="ALL" on="true"/>
        </Masks>
        <Dumps>
        </Dumps>
    </Log>
    <ProductionNodes>
        <Recording file="Recording.oni" />

        <!-- Set global mirror -->
        <GlobalMirror on="true"/>

    </ProductionNodes>
</OpenNI>

Everything looks ok, but when I try to run my program, I get:

Open failed: Function was not implemented!

What could be the problem?

Answer 1

The problem were the two following lines:

    <!-- Set global mirror -->
    <GlobalMirror on="true"/>

After removing them, my program works fine.
