      The Audio input is an *AMR encoding that's specific to phones and is difficult to find freeware converters. 

      Stream #0.1(jpn): Audio: samr / 0x726D6173, 8000 Hz, mono

      AMR support is typically disabled in ffmpeg builds since there are stronger license restrictions.  Strictly speaking, there are restrictions for MP3, MP4, etc. as well but somehow AMR is special.  I don't know all the details but I remember.

      You could try other converters like SUPER, WinFF, or AviDemux to see if they compiled in AMR support:
