[meta-freescale] Video play failed with gst-launch

[kongling]

Hi, everyone   I'm trying to play video on MCIMX6Q-SDP, But got some errors.   log:   #gst-launch-1.0 playbin uri=file:///opt/test/004.mp4 video-sink=imxeglvivsinkSetting pipeline to PAUSED...Pipeline is PREROLLING...Missing element: MPEG-4 AAC decoder
   It seems like there's no MPEG-4 AAC decoder in filesystem.   Where to find the decoder or how to port it into my filesystem?
