    [GStreamer] Include MpegAudioParse plugin in Brcm Nexus gstreamer pipeline
    https://bugs.webkit.org/show_bug.cgi?id=268559

    Reviewed by Xabier Rodriguez-Calvar.

    On broadcom/nexus with progressive audio, gst_element_query_duration()
    returns wrong values, which is avoided by forcing mpegaudioparse.
