----------------------------------------------------------
>From the readme of that c code:
> The files contain only data, i.e., there is no header.
So that'll be why ffmpeg and friends can't play it. However, coder supports the
-mime option, which does seem to produce files mplayer likes
I also did find this snippet, which looks promising:
> When using the MIME file storage format the encoded bitstream file starts with
> 9-byte magic number "#!AMR-WB\n"
Any chance you could find a WB+ file so we can see if that begins #!AMR-WB+\n
or similar?
