Profile part of the Profile, tier and level structure.

Fields

profile_space: u8

Decoders shall ignore the CVS when general_profile_space is not equal to 0.

tier_flag: bool

Specifies the tier context for the interpretation of general_level_idc as specified in ISO/IEC 23008-2 - Annex A.

profile_idc: u8

When general_profile_space is equal to 0, indicates a profile to which the CVS conforms as specified in ISO/IEC 23008-2 - Annex A.

profile_compatibility_flag: ProfileCompatibilityFlags

profile_compatibility_flag[j] equal to true, when general_profile_space is equal to 0, indicates that the CVS conforms to the profile indicated by general_profile_idc equal to j as specified in ISO/IEC 23008-2 - Annex A.

progressive_source_flag: bool

• If general_progressive_source_flag is equal to true and general_interlaced_source_flag is equal to false, the source scan type of the pictures in the CVS should be interpreted as progressive only.
• Otherwise, if general_progressive_source_flag is equal to false and general_interlaced_source_flag is equal to true, the source scan type of the pictures in the CVS should be interpreted as interlaced only.
• Otherwise, if general_progressive_source_flag is equal to false and general_interlaced_source_flag is equal to false, the source scan type of the pictures in the CVS should be interpreted as unknown or unspecified.
• Otherwise (general_progressive_source_flag is equal to true and general_interlaced_source_flag is equal to true), the source scan type of each picture in the CVS is indicated at the picture level using the syntax element source_scan_type in a picture timing SEI message.

interlaced_source_flag: bool

See progressive_source_flag.

non_packed_constraint_flag: bool

Equal to true specifies that there are no frame packing arrangement SEI messages, segmented rectangular frame packing arrangement SEI messages, equirectangular projection SEI messages, or cubemap projection SEI messages present in the CVS.

Equal to false indicates that there may or may not be one or more frame packing arrangement SEI messages, segmented rectangular frame packing arrangement SEI messages, equirectangular projection SEI messages, or cubemap projection SEI messages present in the CVS.

frame_only_constraint_flag: bool

Equal to true specifies that field_seq_flag is equal to 0.

Equal to false indicates that field_seq_flag may or may not be equal to 0.

additional_flags: ProfileAdditionalFlags

Any additional flags that may be present in the profile.

inbld_flag: Option<bool>

Equal to true specifies that the INBLD capability as specified in ISO/IEC 23008-2 - Annex F is required for decoding of the layer to which the profile_tier_level( ) syntax structure applies.

Equal to false specifies that the INBLD capability as specified in ISO/IEC 23008-2 - Annex F is not required for decoding of the layer to which the profile_tier_level( ) syntax structure applies.

level_idc: Option<u8>

Indicates a level to which the CVS conforms as specified in ISO/IEC 23008-2 - Annex A.

Always present for the general profile.

Trait Implementations

impl Clone for Profile

fn clone(&self) -> Profile

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Profile

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

Formats the value using the given formatter.

impl PartialEq for Profile

fn eq(&self, other: &Profile) -> 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.
