<p>This specification defines the byte stream formats for use with the <a def-id="mse-spec"></a> specification [[!MEDIA-SOURCE]].</p>
</section>
<section id="sotd">
<p>The working group maintains <a href="https://github.com/w3c/media-source/issues">a list of all bug reports that the editors have not yet tried to address</a>; there may also be open bugs in the <a href="http://w3.org/brief/Mjcw">previous bug tracker</a>.</p>
<p>Implementors should be aware that this specification is not stable. <strong>Implementors who are not taking part in the discussions are likely to find the specification changing out from under them in incompatible ways.</strong> Vendors interested in implementing this specification before it eventually reaches the Candidate Recommendation stage should join the mailing list mentioned below and take part in the discussions.</p>
</section>
<section id="purpose">
<h2>Purpose</h2>
<p>This registry is intended to enhance interoperability among implementations and users of
<a class="externalDFN">SourceBuffer</a> objects described in the
<a def-id="mse-spec"></a>(MSE) specification. In particular, this registry provides the means (1) to identify
and avoid MIME-type collisions among byte stream formats, and (2) to disclose information about byte stream formats accepted by MSE
implementations to promote interoperability.
</section>
<section id="organization">
<h2>Organization</h2>
<p>The registry maintains a mapping between MIME-type/subtype pairs and byte stream format specifications. The byte stream format specifications describe the
structure and semantics of byte streams accepted by <a class="externalDFN">SourceBuffer</a> objects
created with the associated MIME-type/subtype pair.</p>
<p>This registry is not intended to include any information on whether a byte stream format is encumbered by intellectual property claims. Implementors and users
are advised to seek appropriate legal counsel in this matter if they intend to implement or use a specific byte stream format.</p>
</section>
<section id="entry-requirements">
<h2>Registration Entry Requirements</h2>
<ol>
<li>Each entry MUST include a unique MIME-type/subtype pair. If the byte stream format is derived-from an existing file format, then it SHOULD use the
MIME-type/subtype pairs typically used for the file format.</li>
<li>Each entry MUST include a <a def-id="generate-timestamps-flag"></a> value that MUST be used by
<a class="externalDFN">SourceBuffer</a> when handling the byte stream format.</li>
<li>Each entry MUST include a link that references a publically available specification. It is recommended that such a specification be made available
without cost (other than reasonable shipping and handling if not available by online means).</li>
<li>Each entry MUST comply with all requirements outlined in the <a def-id="byte-stream-formats-section"></a>
of the <a def-id="mse-spec"></a> specification.</li>
<li>Candidate entries MUST be announced on <a href="mailto:public-html-media@w3.org">public-html-media@w3.org</a>(<a href="mailto:public-html-media-request@w3.org">subscribe</a>,
<a href="http://lists.w3.org/Archives/Public/public-html-media/">archives</a>) so they can be discussed and evaluated for compliance before being added to the
registry.</li>
</ol>
<p>If a registration fails to satisfy a mandatory requirement specified above, then it MAY be removed from the registry (without prejudice).
