+ * @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 (gppmux).
+ * 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 (<link linkend="GstMP4Mux--movie-timescale">movie-timescale</link>,
+ * <link linkend="GstMP4Mux--trak-timescale">trak-timescale</link>) 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 <link linkend="GstMP4Mux--faststart">faststart</link> 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 <link linkend="GstMP4Mux--fragment-duration">fragment-duration</link>.
+ * If such fragmented layout is intended for streaming purposes, then
+ * <link linkend="GstMP4Mux--streamable">streamable</link> allows foregoing to add
+ * index metadata (at the end of file).
+ *
+ * <link linkend="GstMP4Mux--dts-method">dts-method</link> allows selecting a
+ * method for managing input timestamps (stay tuned for 0.11 to have this
+ * automagically settled).  The default delta/duration method should handle nice
+ * (aka perfect streams) just fine, but may experience problems otherwise
+ * (e.g. input stream with re-ordered B-frames and/or with frame dropping).
+ * The re-ordering approach re-assigns incoming timestamps in ascending order
+ * to incoming buffers and offers an alternative in such cases.  In cases where
+ * that might fail, the remaining method can be tried, which is exact and
+ * according to specs, but might experience playback on not so spec-wise players.
