}

Stateless backend methods specific to VP9.

Required Methods

fn new_sequence(&mut self, header: &Header) -> StatelessBackendResult<()>

Called when new stream parameters are found.

fn new_picture(&mut self, timestamp: u64) -> NewPictureResult<Self::Picture>

Allocate all resources required to process a new picture.

fn submit_picture( &mut self, picture: Self::Picture, hdr: &Header, reference_frames: &[Option<Self::Handle>; 8], bitstream: &[u8], segmentation: &[Segmentation; 8], ) -> StatelessBackendResult<Self::Handle>

Called when the decoder wants the backend to finish the decoding operations for picture.

This call will assign the ownership of the BackendHandle to the Picture and then assign the ownership of the Picture to the Handle.
