anything about the ‘ffdec_mpe2dec’. But the most decoders generates
a pad per data (video, audio, etc - anything else doesn’t matter). So you
should handle these pads at the pad-added-event separately. After that, you
should queue these data’s into an encoder and then pushing this into a sink-element.
