Here you have our sample file.

http://www.dave-tech.it/download/tmp/testLE.722

It "should" be a g.722 ADPCM encoded
audio file (it's a short part of a Metallica's song --- Muster of
puppets maybe?). I said "should" because it's the output of a "black
box" that use this encoder. It can contain some encapsulation.
Our first proposal was to have a tested g.722 player for listen our
encoded sample and say " ok this is g.722 ADPCM format" then include
this player ( or add this decoder / encoder to Mplayer) for our kit.

We tryed to use ffmpeg without success. We would like to decode our
g.722 file into a pcm or something we can play. Could you please give us
some hint about the correct command line or options to use with ffmpeg?
The only thing we got was a "unrecognized audio format".


Thanks and regards

Lena
