gstreamer mfw_mp3encoder does not work

My platform is Yocto Linux 2.0.50 4.0.0 on wandboard iMX6 solo.

 

I can use alsa util -- arecord -- to capture a raw wav clip from mic input.  But I want to get MP3 or AAC audio to work.

 

I tried this gstreamer pipeline:

gst-launch  alsasrc ! queue ! audioconvert ! queue ! mfw_mp3encoder ! filesink location=test.mp3

 

I appreciate any help, gstreamer or some standalone recording program to capture AAC or MP3 audio.

 

Also I wonder if there is an AAC encoder?  MP3 or AAC, Which is more efficient in size and CPU needs?

 

Many thanks,

Norman
