Did you comment out line 134?:

  gst_element_link (decad, adqueue);

Also check if all FSL plugins are installed:
mx27# gst-inspect | grep mfw
mfw_vpudecoder:  mfw_vpudecoder: Freescale: Hardware (VPU) Decoder
mfw_v4lsrc:  mfw_v4lsrc: Freescale Video Source plug-in
mfw_vpuencoder:  mfw_vpuencoder: Freescale: Hardware (VPU) Encoder
mfw_v4lsink:  mfw_v4lsink: Freescale: v4l_sink
mfw_avidemuxer:  mfw_avidemuxer: FSL Avi Demuxer
mfw_mp4demuxer:  mfw_mp4demuxer: freescale-mp4 demuxer plugin

Here on my iMX27ADS it works fine:
