Dear all,

I was suprised to see that aac decoding was not supported in 
gst-fsl-plugin_3.0.9. After some investigation i discovered that 
makefile.am was not having the AAC option for imx6.
Please see patch attachment.
I add a try and now m4a file are correctly supported in gstreamer.
Is there a reason to disable aac dec on imx6 or is it only a mistake ?
Best regards.

Stéphane
