Struct Vp9Decoder 

pub struct Vp9Decoder { /* private fields */ }

A stateful VP9 decoder for the encoder’s subset.

Maintains the eight reference-buffer slots across a frame sequence so inter frames can motion-compensate against the previous reconstruction. Decode a keyframe first (which populates every slot), then feed each subsequent inter frame to Vp9Decoder::decode_frame.

Implementations

impl Vp9Decoder

pub fn new() -> Self

A decoder with no reference history. The first frame must be a keyframe.

pub fn decode_frame( &mut self, bytes: &[u8], ) -> Result<Rc<FrameBuffer>, DecodeError>

Decode one frame (keyframe or inter) from bytes, update the reference slots per the frame’s refresh mask, and return the reconstruction (borders already extended, so it can serve directly as a later reference).

An inter frame decoded before any keyframe — or one referencing an empty slot — is rejected with DecodeError::Corrupt rather than reading uninitialized state.

Trait Implementations

impl Default for Vp9Decoder

fn default() -> Self

Returns the “default value” for a type.
