Struct SubLayerOrderingInfo

pub struct SubLayerOrderingInfo {
    pub sps_max_dec_pic_buffering_minus1: Vec<u64>,
    pub sps_max_num_reorder_pics: Vec<u64>,
    pub sps_max_latency_increase_plus1: Vec<u32>,
}

Info for each sub-layer in the SPS.

Directly part of SPS RBSP.

Fields

sps_max_dec_pic_buffering_minus1: Vec<u64>

sps_max_dec_pic_buffering_minus1[i] plus 1 specifies the maximum required size of the decoded picture buffer for the CVS in units of picture storage buffers when HighestTid is equal to i.

sps_max_num_reorder_pics: Vec<u64>

sps_max_num_reorder_pics[i] indicates the maximum allowed number of pictures with PicOutputFlag equal to 1 that can precede any picture with PicOutputFlag equal to 1 in the CVS in decoding order and follow that picture with PicOutputFlag equal to 1 in output order when HighestTid is equal to i.

sps_max_latency_increase_plus1: Vec<u32>

sps_max_latency_increase_plus1[i] not equal to 0 is used to compute the value of SpsMaxLatencyPictures[i], which specifies the maximum number of pictures with PicOutputFlag equal to 1 that can precede any picture with PicOutputFlag equal to 1 in the CVS in output order and follow that picture with PicOutputFlag equal to 1 in decoding order when HighestTid is equal to i.

Implementations

impl SubLayerOrderingInfo

pub fn sps_max_latency_pictures(&self) -> Vec<Option<u64>>

Specifies the maximum number of pictures with PicOutputFlag equal to 1 that can precede any picture with PicOutputFlag equal to 1 in the CVS in output order and follow that picture with PicOutputFlag equal to 1 in decoding order when HighestTid is equal to i.

Calculates the full SpsMaxLatencyPictures array.

Use SubLayerOrderingInfo::sps_max_latency_pictures_at to only calculate one specific value SpsMaxLatencyPictures[i].

SpsMaxLatencyPictures[i] = sps_max_num_reorder_pics[i] + sps_max_latency_increase_plus1[i] − 1 (7-9)

ISO/IEC 23008-2 - 7.4.3.2

pub fn sps_max_latency_pictures_at(&self, i: usize) -> Option<u64>

Calculates SpsMaxLatencyPictures[i].

See sps_max_latency_pictures for details.

SpsMaxLatencyPictures[i] = sps_max_num_reorder_pics[i] + sps_max_latency_increase_plus1[i] − 1 (7-9)

Trait Implementations

impl Clone for SubLayerOrderingInfo

fn clone(&self) -> SubLayerOrderingInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SubLayerOrderingInfo

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

Formats the value using the given formatter.

impl PartialEq for SubLayerOrderingInfo

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