Is there AAC mux plugin in GStreamer?

[Jeongmo Yang]

Hi, All.
I am recorder developer on linux.
AAC codec can be created with m4a and aac file extension.
As I know, m4a is mpeg4 container without video data, so it can be created by ffmux_mp4 plugin.
but, I can not find the mux plugin for creating aac extension, like ffmux_mp4.
Is there AAC mux plugin in GStreamer?
