| <p>This element merges streams (audio and video) into QuickTime(.mov) 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 (gppmux). |
| 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-qtmux.html#GstQTMux--movie-timescale" title="The “movie-timescale” property"><span class="type">“movie-timescale”</span></a>, <a class="link" href="gst-plugins-good-plugins-qtmux.html#GstQTMux--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-qtmux.html#GstQTMux--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-qtmux.html#GstQTMux--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-qtmux.html#GstQTMux--streamable" title="The “streamable” property"><span class="type">“streamable”</span></a> allows foregoing to add index metadata (at the end of |
| file).</p> |
| <p>When the maximum duration to be recorded can be known in advance, <a class="link" href="gst-plugins-good-plugins-qtmux.html#GstQTMux"><span class="type">GstQTMux</span></a> |
| also supports a 'Robust Muxing' mode. In robust muxing mode, space for the |
| headers are reserved at the start of muxing, and rewritten at a configurable |
| interval, so that the output file is always playable, even if the recording |
| is interrupted uncleanly by a crash. Robust muxing mode requires a seekable |
| output, such as filesink, because it needs to rewrite the start of the file.</p> |
| <p>To enable robust muxing mode, set the <span class="type">“reserved-moov-update-period”</span> |
| and <span class="type">“reserved-max-duration”</span> property. Also present is the |
| <span class="type">“reserved-bytes-per-sec”</span> property, which can be increased if |
| for some reason the default is not large enough and the initial reserved |
| space for headers is too small. Applications can monitor the |
| <span class="type">“reserved-duration-remaining”</span> property to see how close to full |
| the reserved space is becoming.</p> |
