[Ffmpeg-devel] Shorten audio FourCC

Shorten audio is not yet supported by MPlayer since it lacks a FourCC in
libavformat/riff.c.  Now adding one would be easy, but the question is
which one to choose.  The obvious choice would be 'shn', but that's just
three characters.  So maybe 'shor' or 'shn '.

Then again, in libavcodec/shorten.c is the following code snippet:

  /* shorten signature */
  if (get_bits_long(&s->gb, 32) != bswap_32(ff_get_fourcc("ajkg"))) {
  av_log(s->avctx, AV_LOG_ERROR, "missing shorten magic 'ajkg'\n");

Does 'ajkg' have any further relationship with Shorten?  Should it be
used as the FourCC?
