Implementations§

source§

impl H264Sps

source

pub fn try_parse(buffer: &[u8]) -> Result<Self, SpsParsingError>

Parses a sequence parameter set from a buffer.

source

pub fn parse_from_avcc(avcc: &Avc1Box) -> Result<Self, SpsParsingError>

Parses a sequence parameter set from an AVC configuration box.

source

pub fn pixel_layout(&self) -> Result<YuvPixelLayout, SpsParsingError>

Return the pixel layout specified in the SPS.

None means that the value in the SPS was invalid.

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>
