Implementations

impl<M, H> VaapiBackend<M, H>

where M: SurfaceMemoryDescriptor, H: Borrow<Surface<M>>,

Trait Implementations

impl<M, H> StatelessAV1EncoderBackend for VaapiBackend<M, H>

where M: SurfaceMemoryDescriptor, H: Borrow<Surface<M>> + 'static,

fn encode_tile_group( &mut self, request: BackendRequest<Self::Picture, Self::Reconstructed>, ) -> StatelessBackendResult<(Self::ReconPromise, Self::CodedPromise)>

Submit a BackendRequest to the backend. This operation returns both a StatelessVideoEncoderBackend::ReconPromise and a StatelessVideoEncoderBackend::CodedPromise with resulting slice data.

impl<M, Handle> StatelessEncoderBackendImport<Handle, Handle> for VaapiBackend<M, Handle>

where M: SurfaceMemoryDescriptor, Handle: Borrow<Surface<M>>,

fn import_picture( &mut self, _metadata: &FrameMetadata, handle: Handle, ) -> StatelessBackendResult<Handle>

Imports the input handle from client and transforms into Picture

impl<M> StatelessEncoderBackendImport<M, Surface<M>> for VaapiBackend<M, Surface<M>>

where M: SurfaceMemoryDescriptor,

fn import_picture( &mut self, meta: &FrameMetadata, handle: M, ) -> StatelessBackendResult<Surface<M>>

Imports the input handle from client and transforms into Picture

impl<M, H> StatelessH264EncoderBackend for VaapiBackend<M, H>

where M: SurfaceMemoryDescriptor, H: Borrow<Surface<M>> + 'static,

fn encode_slice( &mut self, request: BackendRequest<H, Reconstructed>, ) -> StatelessBackendResult<(Self::ReconPromise, Self::CodedPromise)>

Submit a BackendRequest to the backend. This operation returns both a StatelessVideoEncoderBackend::CodedPromise and a StatelessVideoEncoderBackend::ReconPromise with resulting slice data.

impl<M, Handle> StatelessVP9EncoderBackend for VaapiBackend<M, Handle>

where M: SurfaceMemoryDescriptor, Handle: Borrow<Surface<M>>,

fn encode_frame( &mut self, request: BackendRequest<Self::Picture, Self::Reconstructed>, ) -> StatelessBackendResult<(Self::ReconPromise, Self::CodedPromise)>

impl<M, Handle> StatelessVideoEncoderBackend<AV1> for VaapiBackend<M, Handle>

where M: SurfaceMemoryDescriptor, Handle: Borrow<Surface<M>>,

type Picture = Handle

Backend’s specific representation of the input frame, transformed with import_picture. Might be a wrapper of the input handle with additional backend specific data or a copy of an input frame in internal backend’s representation.

type Reconstructed = Reconstructed

Backend’s reconstructed frame handle.

type CodedPromise = CodedOutputPromise<M, Handle>

Backend’s specific BackendPromise for bitstream, a result of StatelessCodec::Request submission.

type ReconPromise = ReadyPromise<<VaapiBackend<M, Handle> as StatelessVideoEncoderBackend<AV1>>::Reconstructed>

Backend’s specific BackendPromise for StatelessVideoEncoderBackend::Reconstructed, a result of StatelessCodec::Request submission.
