Description

Trying to play back the attached file produces this warning (file still works):
0:00:00.037295790 4609 0x7fe5780a1540 WARN qtdemux qtdemux.c:8576:qtdemux_tag_add_revdns:<qtdemux0> This tag com.apple.iTunes:cdec type:1 is not mapped, file a bug at bugzilla.gnome.org

This is the pipeline I use:
GST_DEBUG='*:2' gst-launch-1.0 playbin uri=file:///tmp/HE-AAC_Stereo_46kbps.m4a audio-sink=alsasink

Plugin Details:
