Trait StatelessVideoEncoderBackend

pub trait StatelessVideoEncoderBackend<Codec>: Sized
where
    Codec: StatelessCodec<Self>,
{
    type Picture: 'static;
    type Reconstructed: 'static;
    type CodedPromise: BackendPromise<Output = Vec<u8>>;
    type ReconPromise: BackendPromise<Output = Self::Reconstructed>;
}

Generic trait for stateless encoder backends

Required Associated Types

type Picture: 'static

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: 'static

Backend’s reconstructed frame handle.

type CodedPromise: BackendPromise<Output = Vec<u8>>

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

type ReconPromise: BackendPromise<Output = Self::Reconstructed>

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

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
