Comment (by johann):


 thanks for looking into the files.

 As for the 3ga files -- do you have any ideas where they could come from?
 Users upload anything and everything and maybe there's some half-broken
 cellphone out there that records these?

 BTW: file says ISO Media, MPEG v4 system, 3GPP to all the 3ga files.

 The wav file with the 0xa100 is using Comverse Infosys Ltd. G723 1,
 according to
 [http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/RIFF.html this].

 Is there a list of TwoCC codecs ffmpeg supports?
