Gstreamer + i.MX6Q - Missing Plug-in

[PaulDeMetrotion]

Am attempting to run an avi file on a custom device which uses the i.MX6Q. Following is the terminal output. I received the following error:

     get GST_MESSAGE_ELEMENT missing-plugin, type=(string)decoder, detail=(GstCaps)audio/x-ac3, bitrate=(int)448000, framed=(boolean)true,      name=(string)"AC-3\ \(ATSC\ A/52\)\ decoder";

Where do I find and how do I install this missing plug-in?

Hi Paul, Freescale beepdec element does not support that audio cap. There is an element which handles the x-ac3 decoding on the gst-plugins-bad, so install it and try the pipeline again.
