Fields

aspect_ratio_info: AspectRatioInfo

AspectRatioInfo if aspect_ratio_info_present_flag is true.

overscan_appropriate_flag: Option<bool>

Equal to true indicates that the cropped decoded pictures output are suitable for display using overscan.

Equal to false indicates that the cropped decoded pictures output contain visually important information in the entire region out to the edges of the conformance cropping window of the picture, such that the cropped decoded pictures output should not be displayed using overscan. Instead, they should be displayed using either an exact match between the display area and the conformance cropping window, or using underscan. As used in this paragraph, the term “overscan” refers to display processes in which some parts near the borders of the cropped decoded pictures are not visible in the display area. The term “underscan” describes display processes in which the entire cropped decoded pictures are visible in the display area, but they do not cover the entire display area. For display processes that neither use overscan nor underscan, the display area exactly matches the area of the cropped decoded pictures.

Only present if overscan_info_present_flag is true.

video_signal_type: VideoSignalType

video_format, video_full_range_flag and colour_primaries, if video_signal_type_present_flag is true.

See VideoSignalType for details.

chroma_loc_info: Option<ChromaLocInfo>

chroma_sample_loc_type_top_field and chroma_sample_loc_type_bottom_field, if chroma_loc_info_present_flag is true.

See ChromaLocInfo for details.

neutral_chroma_indication_flag: bool

Equal to true indicates that the value of all decoded chroma samples is equal to 1 << (BitDepthC − 1).

Equal to false provides no indication of decoded chroma sample values.

field_seq_flag: bool

Equal to true indicates that the CVS conveys pictures that represent fields, and specifies that a picture timing SEI message shall be present in every access unit of the current CVS.

Equal to false indicates that the CVS conveys pictures that represent frames and that a picture timing SEI message may or may not be present in any access unit of the current CVS.

frame_field_info_present_flag: bool

Equal to true specifies that picture timing SEI messages are present for every picture and include the pic_struct, source_scan_type, and duplicate_flag syntax elements.

Equal to false specifies that the pic_struct syntax element is not present in picture timing SEI messages.

default_display_window: DefaultDisplayWindow

def_disp_win_left_offset, def_disp_win_right_offset, def_disp_win_top_offset and def_disp_win_bottom_offset, if default_display_window_flag is true.

See DefaultDisplayWindow for details.

vui_timing_info: Option<VuiTimingInfo>

vui_num_units_in_tick, vui_time_scale, vui_poc_proportional_to_timing_flag and vui_num_ticks_poc_diff_one_minus1, if vui_timing_info_present_flag is true.

See VuiTimingInfo for details.

bitstream_restriction: BitStreamRestriction

tiles_fixed_structure_flag, motion_vectors_over_pic_boundaries_flag, restricted_ref_pic_lists_flag, min_spatial_segmentation_idc, max_bytes_per_pic_denom, max_bits_per_min_cu_denom, log2_max_mv_length_horizontal and log2_max_mv_length_vertical, if bitstream_restriction_flag is true.

See BitStreamRestriction for details.

Trait Implementations

impl Clone for VuiParameters

fn clone(&self) -> VuiParameters

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VuiParameters

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

Formats the value using the given formatter.

impl PartialEq for VuiParameters

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