* @short_description: Muxer for quicktime(.mov) files
*
+ * This element merges streams (audio and video) into QuickTime(.mov) files.
+ *
+ * The following background intends to explain why various similar muxers
+ * are present in this plugin.
+ *
+ * The
+ * QuickTime file format specification served as basis for the MP4 file
+ * format specification (mp4mux), and as such the QuickTime file structure is
+ * nearly identical to the so-called ISO Base Media file format defined in
+ * ISO 14496-12 (except for some media specific parts).
+ * In turn, the latter ISO Base Media format was further specialized as a
+ * Motion JPEG-2000 file format in ISO 15444-3 (mj2mux)
+ * and in various 3GPP(2) specs (gppmux).
+ * The fragmented file features defined (only) in ISO Base Media are used by
+ * ISMV files making up (a.o.) Smooth Streaming (ismlmux).
