    \brief The QPlatformMediaRecorder class provides access to the recording
    functionality.

    This control provides a means to set the \l {outputLocation()}{output location},
    and record(), pause(), resume(), and stop() recording.  It also
    provides feedback on the \l {duration()}{duration} of the recording.

    The \a location can be relative or empty;
