Module stateless

Stateless decoders.

Stateless here refers to the backend API targeted by these decoders. The decoders themselves do hold the decoding state so the backend doesn’t need to.

The StatelessDecoder struct is the basis of all stateless decoders. It is created by combining a codec codec to a backend, after which bitstream units can be submitted through the StatelessDecoder::decode method.

Structs

StatelessDecoder

A struct that serves as a basis to implement a stateless decoder.

StatelessDecoderFormatNegotiator

Helper to implement DecoderFormatNegotiator for stateless decoders.

Enums

DecodeError

Error returned by the StatelessVideoDecoder::decode method.

NewPictureError

Error returned by new_picture methods of the backend, usually to indicate which kind of resource is needed before the picture can be successfully created.

NewStatelessDecoderError

PoolLayer

Controls the pool returned by StatelessVideoDecoder::frame_pool.

StatelessBackendError

Error returned by stateless backend methods.

Traits

StatelessCodec

StatelessDecoderBackend

Common trait shared by all stateless video decoder backends, providing codec-independent methods.

StatelessDecoderBackendPicture

Specifies the type of picture that a backend will create for a given codec.

StatelessVideoDecoder

Stateless video decoder interface.
