Implementations

impl SeqParameterSet

pub fn from_bits<R: BitRead>(r: R) -> Result<SeqParameterSet, SpsError>

pub fn id(&self) -> ParamSetId

pub fn profile(&self) -> Profile

pub fn level(&self) -> Level

pub fn log2_max_frame_num(&self) -> u8

returned value will be in the range 4 to 16 inclusive

pub fn pixel_dimensions(&self) -> Result<(u32, u32), SpsError>

Helper to calculate the pixel-dimensions of the video image specified by this SPS, taking into account sample-format, interlacing and cropping.

pub fn rfc6381(&self) -> Codec

pub fn fps(&self) -> Option<f64>

Trait Implementations

impl Clone for SeqParameterSet

fn clone(&self) -> SeqParameterSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SeqParameterSet

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

Formats the value using the given formatter.

impl PartialEq<SeqParameterSet> for SeqParameterSet

fn eq(&self, other: &SeqParameterSet) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
