Media Handler Header Atom (`'mdhd'` )

The media handler header atom holds the media timescale and duration.

The flags field is not used, and should be set to 0.

The creation time and modification time fields are used normally.

The time scale is the number of time units that pass in one second for the hint track. This may not be the same time scale in use by the track being hinted.

The duration is the duration of the media track in media time scale units.

The language and quality fields mirror the settings of the media track being hinted.
