/**
* SECTION:element-mp4mux
* @short_description: Muxer for ISO MPEG-4 (.mp4) files
*
* This element merges streams (audio and video) into ISO MPEG-4 (.mp4) 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 (3gppmux).
* The fragmented file features defined (only) in ISO Base Media are used by
* ISMV files making up (a.o.) Smooth Streaming (ismlmux).
*
* A few properties (#GstMp4Mux:movie-timescale, #GstMp4Mux:trak-timescale)
* allow adjusting some technical parameters, which might be useful in (rare)
* cases to resolve compatibility issues in some situations.
*
* Some other properties influence the result more fundamentally.
* A typical mov/mp4 file's metadata (aka moov) is located at the end of the
* file, somewhat contrary to this usually being called "the header".
* However, a #GstMp4Mux:faststart file will (with some effort) arrange this to
* be located near start of the file, which then allows it e.g. to be played
* while downloading. Alternatively, rather than having one chunk of metadata at
* start (or end), there can be some metadata at start and most of the other
* data can be spread out into fragments of #GstMp4Mux:fragment-duration.
* If such fragmented layout is intended for streaming purposes, then
* #GstMp4Mux:streamable allows foregoing to add index metadata (at the end of
* file).
