A file can be decomposed into basic objects very simply, and the structure of the objects is implied from their type. </p><p>Files conforming to the ISO base media file format are formed as a series of objects, called "boxes". All data is contained in boxes, and there is no other data within the file. This includes any initial signature required by the specific file format. The "box" is an object-oriented building block defined by a unique type identifier and length. It was called an "atom" in some specifications (e.g., the first definition of the MP4 file format).<sup id="cite_ref-iso-mpeg4part12_3-2" class="reference"><a href="#cite_note-iso-mpeg4part12-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> </p><p>A presentation (motion sequence) may be contained in several files.

These are set in a box named file type box ("ftyp"), which must be placed in the beginning of the file. It is somewhat analogous to the so-called <a href="/wiki/Fourcc" class="mw-redirect" title="Fourcc">fourcc</a> code, used for a similar purpose for media embedded in <a href="/wiki/Audio_Video_Interleave" title="Audio Video Interleave">AVI</a> container format.<sup id="cite_ref-ftyp-def_59-0" class="reference"><a href="#cite_note-ftyp-def-59"><span class="cite-bracket">[</span>59<span class="cite-bracket">]</span></a></sup> A brand might indicate the type of encoding used, how the data of each encoding is stored, constraints and extensions that are applied to the file, the compatibility, or the intended usage of the file. Brands are printable four-character codes. A file type box contains two kinds of brands. One is "major_brand", which identifies the specification of the best use for the file. It is followed by "minor_version", an informative 4-byte integer for the minor version of the major brand. The second kind of brand is "compatible_brands", which identifies multiple specifications to which the file complies. All files shall contain a file type box, but for compatibility reasons with an earlier version of the specification, files may be conformant to ISO/IEC base media file format and not contain a file type box. In that case, they should be read as if they contained an <i>ftyp</i> with a major and compatible brand "mp41" (MP4 v1 – ISO 14496-1, Chapter 13).<sup id="cite_ref-iso-mpeg4part12_3-4" class="reference"><a href="#cite_note-iso-mpeg4part12-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> Some in-use brands (ftyps) are not registered and can be found on some webpages.<sup id="cite_ref-ftyp_36-2" class="reference"><a href="#cite_note-ftyp-36"><span class="cite-bracket">[</span>36<span class="cite-bracket">]</span></a></sup> </p><p>A multimedia file structured upon ISO/IEC base media file format may be compatible with more than one concrete specification, and it is therefore not always possible to speak of a single "type" or "brand" for the file.

In spite of that, when a derived specification is written, a new file extension will be used, a new MIME type, and a new Macintosh file type.<sup id="cite_ref-iso-mpeg4part12_3-5" class="reference"><a href="#cite_note-iso-mpeg4part12-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Streaming">Streaming</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=ISO_base_media_file_format&action=edit&section=5" title="Edit section: Streaming"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The ISO/IEC base media file format supports <a href="/wiki/Streaming_media" title="Streaming media">streaming</a> of media data over a network as well as local playback. A file that supports streaming includes information about the data units to stream (how to serve the <a href="/wiki/Elementary_stream" class="mw-redirect" title="Elementary stream">elementary stream</a> data in the file over streaming protocols). This information is placed in additional tracks of the file called "hint" tracks. Separate "hint" tracks for different protocols may be included within the same file. The media will play over all such protocols without making any additional copies or versions of the media data. Existing media can be easily made streamable for other specific protocols by the addition of appropriate hint tracks. The media data itself need not be reformatted in any way. The streams sent by the servers under the direction of the hint tracks, need to contain no trace of file-specific information. When the presentation is played back locally (not streamed), the hint tracks may be ignored. Hint tracks may be created by an authoring tool or may be added to an existing file (presentation) by a hinting tool.<sup id="cite_ref-iso-mpeg4part12_3-6" class="reference"><a href="#cite_note-iso-mpeg4part12-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> In media authored for progressive download, the <b>moov</b> box, which contains the index of frames, should precede the movie data <b>mdat</b> box.<sup id="cite_ref-From_Google_I/O_2009_–_Mastering_the_Android_Media_Framework_60-0" class="reference"><a href="#cite_note-From_Google_I/O_2009_–_Mastering_the_Android_Media_Framework-60"><span class="cite-bracket">[</span>60<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="References">References</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=ISO_base_media_file_format&action=edit&section=6" title="Edit section: References"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <style data-mw-deduplicate="TemplateStyles:r1239543626">.mw-parser-output .reflist{margin-bottom:0.5em;list-style-type:decimal}@media screen{.mw-parser-output .reflist{font-size:90%}}.mw-parser-output .reflist .references{font-size:100%;margin-bottom:0;list-style-type:inherit}.mw-parser-output .reflist-columns-2{column-width:30em}.mw-parser-output .reflist-columns-3{column-width:25em}.mw-parser-output .reflist-columns{margin-top:0.3em}.mw-parser-output .reflist-columns ol{margin-top:0}.mw-parser-output .reflist-columns li{page-break-inside:avoid;break-inside:avoid-column}.mw-parser-output .reflist-upper-alpha{list-style-type:upper-alpha}.mw-parser-output .reflist-upper-roman{list-style-type:upper-roman}.mw-parser-output .reflist-lower-alpha{list-style-type:lower-alpha}.mw-parser-output .reflist-lower-greek{list-style-type:lower-greek}.mw-parser-output .reflist-lower-roman{list-style-type:lower-roman}</style><div class="reflist"> <div class="mw-references-wrap mw-references-columns"><ol class="references"> <li id="cite_note-loc-1"><span class="mw-cite-backlink">^ <a href="#cite_ref-loc_1-0"><sup><i><b>a</b></i></sup></a> <a href="#cite_ref-loc_1-1"><sup><i><b>b</b></i></sup></a></span> <span class="reference-text"><style data-mw-deduplicate="TemplateStyles:r1238218222">.mw-parser-output cite.citation{font-style:inherit;word-wrap:break-word}.mw-parser-output .citation q{quotes:"\"""\"""'""'"}.mw-parser-output .citation:target{background-color:rgba(0,127,255,0.133)}.mw-parser-output .id-lock-free.id-lock-free a{background:url("//upload.wikimedia.org/wikipedia/commons/6/65/Lock-green.svg")right 0.1em center/9px no-repeat}.mw-parser-output .id-lock-limited.id-lock-limited a,.mw-parser-output .id-lock-registration.id-lock-registration a{background:url("//upload.wikimedia.org/wikipedia/commons/d/d6/Lock-gray-alt-2.svg")right 0.1em center/9px no-repeat}.mw-parser-output .id-lock-subscription.id-lock-subscription a{background:url("//upload.wikimedia.org/wikipedia/commons/a/aa/Lock-red-alt-2.svg")right 0.1em center/9px no-repeat}.mw-parser-output .cs1-ws-icon a{background:url("//upload.wikimedia.org/wikipedia/commons/4/4c/Wikisource-logo.svg")right 0.1em center/12px no-repeat}body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-free a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-limited a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-registration a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-subscription a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .cs1-ws-icon a{background-size:contain;padding:0 1em 0 0}.mw-parser-output .cs1-code{color:inherit;background:inherit;border:none;padding:inherit}.mw-parser-output .cs1-hidden-error{display:none;color:var(--color-error,#d33)}.mw-parser-output .cs1-visible-error{color:var(--color-error,#d33)}.mw-parser-output .cs1-maint{display:none;color:#085;margin-left:0.3em}.mw-parser-output .cs1-kern-left{padding-left:0.2em}.mw-parser-output .cs1-kern-right{padding-right:0.2em}.mw-parser-output .citation .mw-selflink{font-weight:inherit}@media screen{.mw-parser-output .cs1-format{font-size:95%}html.skin-theme-clientpref-night .mw-parser-output .cs1-maint{color:#18911f}}@media screen and (prefers-color-scheme:dark){html.skin-theme-clientpref-os .mw-parser-output .cs1-maint{color:#18911f}}</style><cite class="citation techreport cs1"><a rel="nofollow" class="external text" href="https://www.loc.gov/preservation/digital/formats/fdd/fdd000079.shtml"><i>ISO Base Media File Format</i></a> (Full draft).
