ext/mad/gstid3tag.c: move from "Codec/(Dem/M)uxer" to "Codec/(Dem/M)uxer/Audio"
Original commit message from CVS: * ext/mad/gstid3tag.c : move from "Codec/(Dem/M)uxer" to "Codec/(Dem/M)uxer/Audio" * gst/wavenc/gstwavenc.c : move from "Codec/Encoder/Audio" to "Codec/Muxer/Audio" * gst/auparse/gstauparse.c : - add code (commented for now) to support audio/x-adpcm on src pad (we have no decoder for those layout yet) * gst/cdxaparse/gstcdxaparse.c : * gst/cdxaparse/gstcdxaparse.h : - partial rewrite using RiffRead (ripped iain's wavparse code) * gst/rtp/gstrtpL16enc.c : typo * gst/rtp/gstrtpgsmenc.c : typo
