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