Fields

version: u8

Version of the tkhd atom format (0 or 1)

flags: [u8; 3]

Flags for the tkhd atom (bit flags for track properties)

creation_time: u64

When the track was created (seconds since Jan 1, 1904 UTC)

modification_time: u64

When the track was last modified (seconds since Jan 1, 1904 UTC)

track_id: u32

Unique identifier for this track within the movie

duration: u64

Duration of the track in movie timescale units

layer: i16

Playback layer (lower numbers are closer to viewer)

alternate_group: i16

Audio balance or stereo balance (-1.0 = left, 0.0 = center, 1.0 = right)

volume: f32

Audio volume level (1.0 = full volume, 0.0 = muted)

matrix: Option<[i32; 9]>

3x3 transformation matrix for video display positioning/rotation

None if matrix is empty or is the identity matrix
