Field Value

Attributes

Remarks

A key for boolean DEFAULT behavior for the track. The track with DEFAULT=true is selected in the absence of a specific user choice. This is currently used in two scenarios: 1) for subtitle tracks, when the user selected 'Default' for the captioning locale. 2) for a #MIMETYPE_IMAGE_ANDROID_HEIC / #MIMETYPE_IMAGE_AVIF track, indicating the image is the primary item in the file.

The associated value is an integer, where non-0 means TRUE. This is an optional field; if not specified, DEFAULT is considered to be FALSE.
