+/**
+ * The sample description table gives detailed information about the coding type used, and any initialization
+ * information needed for that coding. <br>
+ * The information stored in the sample description box after the entry-count is both track-type specific as
+ * documented here, and can also have variants within a track type (e.g. different codings may use different
+ * specific information after some common fields, even within a video track).<br>
+ * For video tracks, a VisualSampleEntry is used; for audio tracks, an AudioSampleEntry. Hint tracks use an
+ * entry format specific to their protocol, with an appropriate name. Timed Text tracks use a TextSampleEntry
+ * For hint tracks, the sample description contains appropriate declarative data for the streaming protocol being
+ * used, and the format of the hint track. The definition of the sample description is specific to the protocol.
+ * Multiple descriptions may be used within a track.<br>
+ * The 'protocol' and 'codingname' fields are registered identifiers that uniquely identify the streaming protocol or
+ * compression format decoder to be used. A given protocol or codingname may have optional or required
+ * extensions to the sample description (e.g. codec initialization parameters). All such extensions shall be within
+ * boxes; these boxes occur after the required fields. Unrecognized boxes shall be ignored.
+ * <br>
+ * Defined in ISO/IEC 14496-12
