50 * @short_description: Muxer for quicktime(.mov) files
52 * This element merges streams (audio and video) into QuickTime(.mov) files.
54 * The following background intends to explain why various similar muxers
55 * are present in this plugin.
57 * The <ulink url="http://www.apple.com/quicktime/resources/qtfileformat.pdf">
58 * QuickTime file format specification</ulink> served as basis for the MP4 file
59 * format specification (mp4mux), and as such the QuickTime file structure is
60 * nearly identical to the so-called ISO Base Media file format defined in
61 * ISO 14496-12 (except for some media specific parts).
62 * In turn, the latter ISO Base Media format was further specialized as a
63 * Motion JPEG-2000 file format in ISO 15444-3 (mj2mux)
64 * and in various 3GPP(2) specs (gppmux).
65 * The fragmented file features defined (only) in ISO Base Media are used by
66 * ISMV files making up (a.o.) Smooth Streaming (ismlmux).
68 * A few properties (#GstQTMux:movie-timescale, #GstQTMux:trak-timescale) allow
69 * adjusting some technical parameters, which might be useful in (rare) cases to
70 * resolve compatibility issues in some situations.
72 * Some other properties influence the result more fundamentally.
73 * A typical mov/mp4 file's metadata (aka moov) is located at the end of the
74 * file, somewhat contrary to this usually being called "the header".
75 * However, a #GstQTMux:faststart file will (with some effort) arrange this to
76 * be located near start of the file, which then allows it e.g. to be played
77 * while downloading. Alternatively, rather than having one chunk of metadata at
78 * start (or end), there can be some metadata at start and most of the other
79 * data can be spread out into fragments of #GstQTMux:fragment-duration.
80 * If such fragmented layout is intended for streaming purposes, then
81 * #GstQTMux:streamable allows foregoing to add index metadata (at the end of
84 * When the maximum duration to be recorded can be known in advance, #GstQTMux
85 * also supports a 'Robust Muxing' mode. In robust muxing mode, space for the
86 * headers are reserved at the start of muxing, and rewritten at a configurable
87 * interval, so that the output file is always playable, even if the recording
88 * is interrupted uncleanly by a crash. Robust muxing mode requires a seekable
89 * output, such as filesink, because it needs to rewrite the start of the file.
91 * To enable robust muxing mode, set the #GstQTMux::reserved-moov-update-period
92 * and #GstQTMux::reserved-max-duration property. Also present is the
93 * #GstQTMux::reserved-bytes-per-sec property, which can be increased if
94 * for some reason the default is not large enough and the initial reserved
95 * space for headers is too small. Applications can monitor the
96 * #GstQTMux::reserved-duration-remaining property to see how close to full
97 * the reserved space is becoming.

151 * The basic building blocks of MP4 files are:
152 * - an 'ftyp' box at the very start
153 * - an 'mdat' box which contains the raw audio/video/subtitle data;
154 * this is just a bunch of bytes, completely unframed and possibly
155 * unordered with no additional meta-information
156 * - a 'moov' box that contains information about the different streams
157 * and what they contain, as well as sample tables for each stream
158 * that tell the demuxer where in the mdat box each buffer/sample is
159 * and what its duration/timestamp etc. is, and whether it's a
161 * Additionally, fragmented MP4 works by writing chunks of data in
162 * pairs of 'moof' and 'mdat' boxes:
163 * - 'moof' boxes, header preceding each mdat fragment describing the
164 * contents, like a moov but only for that fragment.
165 * - a 'mfra' box for Fragmented MP4, which is written at the end and
166 * contains a summary of all fragments and seek tables.
168 * Currently mp4mux can work in 4 different modes / generate 4 types
169 * of output files/streams:
171 * - Normal mp4: mp4mux will write a little ftyp identifier at the
172 * beginning, then start an mdat box into which it will write all the
173 * sample data. At EOS it will then write the moov header with track
174 * headers and sample tables at the end of the file, and rewrite the
175 * start of the file to fix up the mdat box size at the beginning.
176 * It has to wait for EOS to write the moov (which includes the
177 * sample tables) because it doesn't know how much space those
178 * tables will be. The output downstream must be seekable to rewrite
179 * the mdat box at EOS.
181 * - Fragmented mp4: moov header with track headers at start
182 * but no sample table, followed by N fragments, each containing
183 * track headers with sample tables followed by some data. Downstream
184 * does not need to be seekable if the 'streamable' flag is TRUE,
185 * as the final mfra and total duration will be omitted.
187 * - Fast-start mp4: the goal here is to create a file where the moov
188 * headers are at the beginning; what mp4mux will do is write all
189 * sample data into a temp file and build moov header plus sample
190 * tables in memory and then when EOS comes, it will push out the
191 * moov header plus sample tables at the beginning, followed by the
192 * mdat sample data at the end which is read in from the temp file
193 * Files created in this mode are better for streaming over the
194 * network, since the client doesn't have to seek to the end of the
195 * file to get the headers, but it requires copying all sample data
196 * out of the temp file at EOS, which can be expensive. Downstream does
197 * not need to be seekable, because of the use of the temp file.
199 * - Robust Muxing mode: In this mode, qtmux uses the reserved-max-duration
200 * and reserved-moov-update-period properties to reserve free space
201 * at the start of the file and periodically write the MOOV atom out
202 * to it. That means that killing the muxing at any point still
203 * results in a playable file, at the cost of wasting some amount of
204 * free space at the start of file. The approximate recording duration
205 * has to be known in advance to estimate how much free space to reserve
206 * for the moov, and the downstream must be seekable.
207 * If the moov header grows larger than the reserved space, an error
208 * is generated - so it's better to over-estimate the amount of space
209 * to reserve. To ensure the file is playable at any point, the moov
210 * is updated using a 'ping-pong' strategy, so the output is never in
