It seems your setup isn't quite right as GStreamer cannot find it's own
java files as indicated by:

java.lang.ClassNotFoundException: Didn't find class "org/freedesktop/gstreamer/androidmedia/GstAmcOnFrameAvailableListener" on path:

amcviddec-omxmarvellvideohwcoda7542 should be the right element to use. 
I would suggest using decodebin or playbin to avoid hardcoding the
element name.
