    encodebin: muxer sink pad is not always a request pad
    
    GstId3Mux sink pad is an always (static) pad. Thus releasing it
    as if a request pad triggers:
    (sound-juicer:11826): GStreamer-CRITICAL **:
    gst_element_release_request_pad: assertion `GST_PAD_PAD_TEMPLATE (pad)
    == NULL || GST_PAD_TEMPLATE_PRESENCE (GST_PAD_PAD_TEMPLATE (pad)) ==
    GST_PAD_REQUEST' failed
