Struct StillPicture 

pub struct StillPicture {
    pub sequence: SequenceHeader,
    pub frame: FrameHeader,
    pub tile_groups: Vec<Range<usize>>,
}

The parsed headers of a still picture, plus a locator for its tile data.

Fields

sequence: SequenceHeader

The sequence header governing the frame.

frame: FrameHeader

The frame (uncompressed) header.

tile_groups: Vec<Range<usize>>

Each tile group’s bytes, in order, as ranges of the frame_data passed to StillPicture::parse.

For an OBU_FRAME the first range lies inside that OBU’s payload, past the byte-aligned frame header; each OBU_TILE_GROUP adds its payload.

Implementations

impl StillPicture

pub fn tile_group_data<'a>(&self, frame_data: &'a [u8]) -> Result<Vec<&'a [u8]>>

The tile groups’ bytes, ready for super::decode_still.

Errors

Returns PixelsError::Malformed if a range lies outside frame_data, which means it is not the buffer these were parsed from.

impl StillPicture

pub fn parse(config_obus: &[u8], frame_data: &[u8]) -> Result<Self>

Parse the headers of a coded still picture.

config_obus is the av1C configuration OBU run; frame_data is the coded frame. A sequence header repeated in frame_data overrides the configuration one, as the spec allows.

Trait Implementations

impl Clone for StillPicture

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StillPicture

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

Formats the value using the given formatter.
