Language tag as per RFC 5646. Mandatory when the subtype is SUBTITLES.
name
nullable string
A descriptive, human-readable name for the track. For example, “Spanish”.
This can be used by the sender UI for example, to create a selection
dialog. If the name is empty the dialog would contain an empty slot.
Identifier of the track’s content. It can be the URL of the track or any
other identifier that allows the receiver to find the content (when the
track is not inband or included in the manifest). For example it can be
the URL of a vtt file.
trackContentType
nullable string
The MIME type of the track content. For example if the track is a vtt
file it will be ‘text/vtt’. This field is needed for out of band tracks,
so it is usually provided if a trackContentId has also been provided. It
is not mandatory if the receiver has a way to identify the content from
the trackContentId, but recommended. The track content type, if provided,
must be consistent with the track type.
trackId
number
Unique identifier of the track within the context of a
chrome.cast.media.MediaInfo object.
