-  //        _recommendation_, you can decode more or less, it just tell you that
-  //        the caller process needs 'minlen' bytes. if it gets less, it will
-  //        call decode_audio() again.
-  //  maxlen = maximum size (bytes) of output. you MUST NOT write more to the
-  //        buffer, it's the upper-most limit!
-  //        note: maxlen will be always greater or equal to sh->audio_out_minsize

-  // you can read the compressed stream using the demux stream functions:
-  //  demux_read_data(sh->ds, buffer, length) - read 'length' bytes to 'buffer'
-  //  ds_get_packet(sh->ds, &buffer) - set ptr buffer to next data packet
-  // (both func return number of bytes or 0 for error)
