Now that #622484 is fixed, one soundconverter user found another aac related
problem.

When transcoding to aac (now with mp4mux), the track count tag and the cover
image are missing. I also found that replaygain tags disappear, but one problem
at a time.

I used the following command to convert to aac:
gst-launch-0.10 filesrc location=TheseAreDays.flac ! queue ! decodebin2 !
audioconvert ! faac profile=2 ! mp4mux ! filesink location=TheseAreDays.mp4

and the result:
