public class SampleDescriptionBox
extends FullBox

8.5.2.1 Definition

• Box Types: �?stsd’
• Container: SampleTableBox (�?stbl’)
• Mandatory: Yes
• Quantity: Exactly one

The sample description table gives detailed information about the coding type used, and any initialization information needed for that coding.

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). For video tracks, a VisualSampleEntry is used, for audio tracks, an AudioSampleEntry and for metadata tracks, a MetaDataSampleEntry. Hint tracks use an entry format specific to their protocol, with an appropriate name.

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.
