* @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 <ulink url="http://www.apple.com/quicktime/resources/qtfileformat.pdf">
* QuickTime file format specification</ulink> 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).
