  29  * An autodetection based on the extension is not a good idea, but we don't care ;-)
  30  *
  31  * You should not add anything here where autodetection can be easily fixed except in
  32  * order to speed up auto-detection, in particular for formats that are often streamed.
  33  * In particular you should not normally add any DEMUXER_TYPE_LAVF, adding the
  34  * format to preferred_list in libmpdemux/demuxer_lavf.c will usually achieve
  35  * the same effect in a much more reliable way.
