Type of level assignment in a LevelAssignmentBox.

Variants

Type0

Type 0: sample groups are used to specify levels, i.e., samples mapped to different sample group description indexes of a particular sample grouping lie in different levels within the identified track; other tracks are not affected and shall have all their data in precisely one level;

Fields

grouping_type: [u8; 4]

Specifies the sample grouping used to map sample group description entries in the SampleGroupDescriptionBox to levels. Level n contains the samples that are mapped to the SampleGroupDescriptionEntry having index n in grouping_type the SampleGroupDescriptionBox having the same values of grouping_type and grouping_type_parameter, if present, as those provided in this box.

Type1

Type 1: as for Type0 except assignment is by a parameterized sample group;

Fields

grouping_type: [u8; 4]

Specifies the sample grouping used to map sample group description entries in the SampleGroupDescriptionBox to levels. Level n contains the samples that are mapped to the SampleGroupDescriptionEntry having index n in grouping_type the SampleGroupDescriptionBox having the same values of grouping_type and grouping_type_parameter, if present, as those provided in this box.

grouping_type_parameter: u32

Specifies the sample grouping used to map sample group description entries in the SampleGroupDescriptionBox to levels. Level n contains the samples that are mapped to the SampleGroupDescriptionEntry having index n in grouping_type the SampleGroupDescriptionBox having the same values of grouping_type and grouping_type_parameter, if present, as those provided in this box.

Type2

Type 2: level assignment is by track (see the SubsegmentIndexBox for the difference in processing of these levels)

Type3

Type 3: level assignment is by track (see the SubsegmentIndexBox for the difference in processing of these levels)

Type4

Type 4: the respective level contains the samples for a sub-track. The sub-tracks are specified through the SubTrackBox; other tracks are not affected and shall have all their data in precisely one level;

Fields

sub_track_id: u32

Specifies that the sub-track identified by sub_track_ID within loop entry j is mapped to level j.

Other(u8)

Other assignment type.

Implementations

impl LevelAssignmentBoxLevelAssignmentType

pub fn assignment_type(&self) -> u8

Returns the assignment type as a u8.

Trait Implementations

impl Debug for LevelAssignmentBoxLevelAssignmentType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for LevelAssignmentBoxLevelAssignmentType

fn eq(&self, other: &LevelAssignmentBoxLevelAssignmentType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
