I tried building the fsl-image-test + gst-plugins-good-id3demux to
enable mp3 playback using gst-launch. But when doing gst-launch
playbin2 uri=file:///path/to/mp3 gst-launch segfaults. If I build
another image with the mad-plugin for gstreamer, and remove
libmfw_gst_mp3dec.so so the mad-plugin is used it plays ok.

Has someone else tried to use the gstreamer plugin provided by
libmfw_gst_mp3dec.so for mp3 playback?

I tried to identify the key elements in the gstreamer pipes:

Working:
id3demux
mpegaudioparse0
mad
pulsesink

Crashing:
id3demux
mpegaudioparse0
mfw_mp3decoder
pulsesink

I've also gotten feedback from the mailing list that the problem exist on SabreSD and SabreLite using e.g. :
$ gst-launch filesrc location=/home/sax.mp3 ! mfw_mp3decoder ! alsasink
