Flags for CompactSampleToGroupBox.

Fields

index_msb_indicates_fragment_local_description: bool

A flag that shall be zero when this box appears inside a TrackBox but may be 0 or 1 when this box appears inside a TrackFragmentBox. When it is 1, it indicates that the most significant bit (MSB) of every sample_group_description_index does not form part of the index number but instead indicates which SampleGroupDescriptionBox the group description is to be found in: if the MSB is 0, the index identifies a group description from the TrackBox’s SampleGroupDescriptionBox; if the MSB is 1, the index identifies a group description from the TrackFragmentBox’s SampleGroupDescriptionBox.

grouping_type_parameter_present: bool

If set, CompactSampleToGroupBox::grouping_type_parameter is present.

pattern_size_code: u8

Inidicates the size of CompactSampleToGroupBoxPattern::pattern_length.

• 0: 4 bits
• 1: 8 bits
• 2: 16 bits
• 3: 32 bits

count_size_code: u8

Inidicates the size of CompactSampleToGroupBoxPattern::sample_count.

• 0: 4 bits
• 1: 8 bits
• 2: 16 bits
• 3: 32 bits

index_size_code: u8

The size of CompactSampleToGroupBoxSampleGroupDescriptionIndex::value.

• 0: 4 bits
• 1: 8 bits
• 2: 16 bits
• 3: 32 bits

Trait Implementations

impl Clone for CompactSampleToGroupBoxFlags

fn clone(&self) -> CompactSampleToGroupBoxFlags
