name="gst-plugins-good-plugins-qtmux.description"></a><h2>Description</h2> 171<p>This element merges streams (audio and video) into QuickTime(.mov) files.</p> 172<p>The following background intends to explain why various similar muxers 173are present in this plugin.</p> 174<p>The <a class="ulink" href="http://www.apple.com/quicktime/resources/qtfileformat.pdf" target="_top"> 175QuickTime file format specification</a> served as basis for the MP4 file 176format specification (mp4mux), and as such the QuickTime file structure is 177nearly identical to the so-called ISO Base Media file format defined in 178ISO 14496-12 (except for some media specific parts). 179In turn, the latter ISO Base Media format was further specialized as a 180Motion JPEG-2000 file format in ISO 15444-3 (mj2mux) 181and in various 3GPP(2) specs (gppmux). 182The fragmented file features defined (only) in ISO Base Media are used by 183ISMV files making up (a.o.) Smooth Streaming (ismlmux).</p> 184<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>, 185<span class="type">“trak-timescale”</span>) allow adjusting some technical parameters, 186which might be useful in (rare) cases to resolve compatibility issues in 187some situations.</p> 188<p>Some other properties influence the result more fundamentally. 189A typical mov/mp4 file's metadata (aka moov) is located at the end of the 190file, somewhat contrary to this usually being called "the header". 191However, 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 192be located near start of the file, which then allows it e.g. to be played 193while downloading. Alternatively, rather than having one chunk of metadata at 194start (or end), there can be some metadata at start and most of the other 195data 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>. 196If such fragmented layout is intended for streaming purposes, then 197<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 198file).</p> 199<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> 200also supports a 'Robust Muxing' mode. In robust muxing mode, space for the 201headers are reserved at the start of muxing, and rewritten at a configurable 202interval, so that the output file is always playable, even if the recording 203is interrupted uncleanly by a crash. Robust muxing mode requires a seekable 204output, such as filesink, because it needs to rewrite the start of the file.</p> 205<p>To enable robust muxing mode, set the <span class="type">“reserved-moov-update-period”</span> 206and <span class="type">“reserved-max-duration”</span> property. Also present is the 207<span class="type">“reserved-bytes-per-sec”</span> property, which can be increased if 208for some reason the default is not large enough and the initial reserved 209space for headers is too small. Applications can monitor the 210<span class="type">“reserved-duration-remaining”</span> property to see how close to full 211the reserved space is becoming.</p> 212<p>Applications that wish to be able to use/edit a file while it is being 213written to by live content, can use the "Robust Prefill Muxing" mode. That 214mode is a variant of the "Robust Muxing" mode in that it will pre-allocate a 215completely valid header from the start for all tracks (i.e. it appears as 216though the file is "reserved-max-duration" long with all samples 217present). This mode can be enabled by setting the 218<span class="type">“reserved-moov-update-period”</span> and <span class="type">“reserved-prefill”</span> 219properties. Note that this mode is only possible with input streams that have 220a fixed sample size (such as raw audio and Prores Video) and that don't 221have reordered samples.</p> 222<div class="refsect2">
