HTML <track> default Attribute
Example
A video with two subtitle tracks. "English" subtitle is the default:
<video width="320" height="240" controls>
<source src="forrest_gump.mp4" type="video/mp4">
<source src="forrest_gump.ogg" type="video/ogg">
<track src="fgsubtitles_en.vtt" kind="subtitles" srclang="en" label="English" default>
<track src="fgsubtitles_no.vtt" kind="subtitles" srclang="no" label="Norwegian">
</video>
Definition and Usage
The default attribute is a boolean attribute.
When present, it specifies that the track is to be enabled if the user's preferences do not indicate that another track would be more appropriate.
Note: There must only be one <track> element with a
default attribute per <media> element.
Browser Support
The numbers in the table specify the first browser version that fully supports the attribute.
