Fields

obu_header: ObuHeader

The OBU header from the OBU that generated this sequence.

seq_profile: Profile

Specifies the features that can be used in the coded video sequence.

still_picture: bool

If set, specifies that the coded video sequence contains only one coded frame. If not set, specifies that the coded video sequence contains one or more coded frames.

reduced_still_picture_header: bool

Specifies that the syntax elements not needed by a still picture are omitted.

frame_width_bits_minus_1: u8

Specifies the number of bits minus 1 used for transmitting the frame width syntax elements.

frame_height_bits_minus_1: u8

Specifies the number of bits minus 1 used for transmitting the frame height syntax elements.

max_frame_width_minus_1: u16

Specifies the maximum frame width minus 1 for the frames represented by this sequence header.

max_frame_height_minus_1: u16

Specifies the maximum frame height minus 1 for the frames represented by this sequence header.

frame_id_numbers_present_flag: bool

Specifies whether frame id numbers are present in the coded video sequence.

delta_frame_id_length_minus_2: u32

Specifies the number of bits minus 2 used to encode delta_frame_id syntax elements.

additional_frame_id_length_minus_1: u32

Used to calculate the number of bits used to encode the frame_id syntax element.

use_128x128_superblock: bool

When set, indicates that superblocks contain 128x128 luma samples. When not set, it indicates that superblocks contain 64x64 luma samples. (The number of contained chroma samples depends on subsampling_x and subsampling_y.)

enable_filter_intra: bool

When set, specifies that the use_filter_intra syntax element may be present. When not set, specifies that the use_filter_intra syntax element will not be present.

enable_intra_edge_filter: bool

Specifies whether the intra edge filtering process should be enabled.

enable_interintra_compound: bool

When set, specifies that the mode info for inter blocks may contain the syntax element interintra. If not set, specifies that the syntax element interintra will not be present.

enable_masked_compound: bool

When set, specifies that the mode info for inter blocks may contain the syntax element compound_type. When not set, specifies that the syntax element compound_type will not be present.

enable_warped_motion: bool

When set, indicates that the allow_warped_motion syntax element may be present. When not set, indicates that the allow_warped_motion syntax element will not be present.

enable_order_hint: bool

When set, indicates that tools based on the values of order hints may be used. When not set, indicates that tools based on order hints are disabled.

enable_dual_filter: bool

When set, indicates that the inter prediction filter type may be specified independently in the horizontal and vertical directions. If the flag is not set, only one filter type may be specified, which is then used in both directions.

enable_jnt_comp: bool

If set, indicates that the distance weights process may be used for inter prediction.

enable_ref_frame_mvs: bool

If set, indicates that the use_ref_frame_mvs syntax element may be present. If not set, indicates that the use_ref_frame_mvs syntax element will not be present.

seq_choose_screen_content_tools: bool

If not set, indicates that the seq_force_screen_content_tools syntax element will be present. If set, indicates that seq_force_screen_content_tools should be set equal to SELECT_SCREEN_CONTENT_TOOLS.

seq_force_screen_content_tools: u32

Equal to SELECT_SCREEN_CONTENT_TOOLS indicates that the allow_screen_content_tools syntax element will be present in the frame header. Otherwise, seq_force_screen_content_tools contains the value for allow_screen_content_tools.

seq_choose_integer_mv: bool

If not set, indicates that the seq_force_integer_mv syntax element will be present. If set, indicates that seq_force_integer_mv should be set equal to SELECT_INTEGER_MV.

seq_force_integer_mv: u32

Equal to SELECT_INTEGER_MV indicates that the force_integer_mv syntax element will be present in the frame header (providing allow_screen_content_tools is equal to 1). Otherwise, seq_force_integer_mv contains the value for force_integer_mv.

order_hint_bits_minus_1: i32

Used to compute OrderHintBits.

order_hint_bits: i32

Specifies the number of bits used for the order_hint syntax element.

enable_superres: bool

If set, specifies that the use_superres syntax element will be present in the uncompressed header. If not set, specifies that the use_superres syntax element will not be present (instead use_superres will be set to 0 in the uncompressed header without being read).

enable_cdef: bool

If set, specifies that cdef filtering may be enabled. If not set, specifies that cdef filtering is disabled.

enable_restoration: bool

If set, specifies that loop restoration filtering may be enabled. If not set, specifies that loop restoration filtering is disabled.

film_grain_params_present: bool

Specifies whether film grain parameters are present in the coded video sequence.

operating_points_cnt_minus_1: u32

Indicates the number of operating points minus 1 present in the coded video sequence. An operating point specifies which spatial and temporal layers should be decoded.

operating_points: [OperatingPoint; 32]

The set of operating points.

decoder_model_info_present_flag: bool

Specifies whether decoder model information is present in the coded video sequence.

decoder_model_info: DecoderModelInfo

The decoder model info.

initial_display_delay_present_flag: bool

Specifies whether initial display delay information is present in the coded video sequence.

timing_info_present_flag: bool

Specifies whether timing info is present in the coded video sequence.

timing_info: TimingInfo

The timing info.

color_config: ColorConfig

The color config.

bit_depth: BitDepth

num_planes: u32

Trait Implementations

impl Clone for SequenceHeaderObu

fn clone(&self) -> SequenceHeaderObu

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SequenceHeaderObu

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

Formats the value using the given formatter.

impl Default for SequenceHeaderObu

fn default() -> SequenceHeaderObu

Returns the “default value” for a type.

impl PartialEq for SequenceHeaderObu

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