Parsed HEVC SPS fields relevant to the pipeline.

Width/height are post-conformance-window (§7.4.3.2.1): per the spec, output luma dimensions = pic_width_in_luma_samples - SubWidthC * (conf_win_left + conf_win_right) (and analogously for height).

Fields

sps_video_parameter_set_id: u8

bit_depth_luma: u8

bit_depth_chroma: u8

width: Option<u32>

height: Option<u32>

conf_win_left_offset: u32

Post-conformance-window crop offsets in chroma samples.

conf_win_right_offset: u32

conf_win_top_offset: u32

conf_win_bottom_offset: u32

log2_max_pic_order_cnt_lsb_minus4: u8

log2_min_luma_coding_block_size_minus3: u8

log2_diff_max_min_luma_coding_block_size: u8

log2_min_luma_transform_block_size_minus2: u8

log2_diff_max_min_luma_transform_block_size: u8

max_transform_hierarchy_depth_inter: u8

max_transform_hierarchy_depth_intra: u8

scaling_list_enabled_flag: bool

sps_sub_layer_ordering_info_present_flag: bool

amp_enabled_flag: bool

sample_adaptive_offset_enabled_flag: bool

pcm_enabled_flag: bool

pcm_loop_filter_disabled_flag: bool

Only meaningful when pcm_enabled_flag is set; defaults to false.

num_short_term_ref_pic_sets: u8

long_term_ref_pics_present_flag: bool

sps_temporal_mvp_enabled_flag: bool

strong_intra_smoothing_enabled_flag: bool

profile_idc: u8

level_idc: u8

tier_flag: bool

max_dec_pic_buffering_minus1: [u8; 7]

Sub-layer DPB management triple, one per sub-layer. Index 0..=sps_max_sub_layers_minus1 are populated; indices above are left at defaults. Vulkan Video requires these to be conveyed via StdVideoH265DecPicBufMgr.

max_num_reorder_pics: [u8; 7]

max_latency_increase_plus1: [u32; 7]

profile_compatibility_flags: u32

profile_compatibility_flag[32] — high bit at index 0. Needed for the Std PTL struct.

general_profile_space: u8

general_profile_space (2 bits) — almost always 0. Part of the hvc1.* codec string prefix.

general_constraint_flags: u64

general_constraint_indicator_flags (48 bits), right-aligned in a u64 (byte 0 = bits 47..40). Emitted as the trailing .XX segments of the hvc1.* codec string.

Trait Implementations

impl Clone for HevcSpsInfo

fn clone(&self) -> HevcSpsInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HevcSpsInfo

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

Formats the value using the given formatter.

impl Default for HevcSpsInfo

fn default() -> HevcSpsInfo

Returns the “default value” for a type.

impl Eq for HevcSpsInfo

impl PartialEq for HevcSpsInfo

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