AAC not played - Error from decoder (ffdec_aac)

Demuxer outputs raw aac data, it does not have any header(ADIF/ADTS) thats
why you get that error message.

To get the correct playable file, you again need to mux this raw aac data
using qtmux and then you get .m4a file.   And to play this .m4a file you
need to have qtdemux in your pipeline if you don't use decodebin2/playbin2.

I hope this will help you.
