| <p>This element merges streams (audio and video) into MJ2 (.mj2) files.</p> |
| <p>The following background intends to explain why various similar muxers |
| are present in this plugin.</p> |
| <p>The <a class="ulink" href="http://www.apple.com/quicktime/resources/qtfileformat.pdf" target="_top"> |
| QuickTime file format specification</a> 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).</p> |
| <p>A few properties (<a class="link" href="gst-plugins-good-plugins-mj2mux.html#GstMJ2Mux--movie-timescale" title="The “movie-timescale” property"><span class="type">“movie-timescale”</span></a>, <a class="link" href="gst-plugins-good-plugins-mj2mux.html#GstMJ2Mux--trak-timescale" title="The “trak-timescale” property"><span class="type">“trak-timescale”</span></a>) |
| allow adjusting some technical parameters, which might be useful in (rare) |
| cases to resolve compatibility issues in some situations.</p> |
| <p>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 |
| <a class="link" href="gst-plugins-good-plugins-mj2mux.html#GstMJ2Mux--faststart" title="The “faststart” property"><span class="type">“faststart”</span></a> 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 <a class="link" href="gst-plugins-good-plugins-mj2mux.html#GstMJ2Mux--fragment-duration" title="The “fragment-duration” property"><span class="type">“fragment-duration”</span></a>. If such |
| fragmented layout is intended for streaming purposes, then |
| <a class="link" href="gst-plugins-good-plugins-mj2mux.html#GstMJ2Mux--streamable" title="The “streamable” property"><span class="type">“streamable”</span></a> allows foregoing to add index metadata (at the end of |
| file).</p> |
