25 * Status of this demuxer:
29 * version v3 w/ 14_4/lpcJ is ok.
30 * version v4/5: - atrac3 is ok.
32 * - raac, racp are ok.
33 * - dnet is twisted "The byte order of the data is reversed
35 * - 28_8 seem problematic.
36 * - sipr should be fine, but our decoder suxx :)
37 * - ralf is unsupported, but hardly any sample exist.
38 * - mp3 is unsupported, one sample exists...
42 * v3 and v4/5 headers are parsed.
