Implementations

impl LibvdaDecoder

pub fn new(backend_type: VdaImplType) -> Result<Self, VideoError>

Create a decoder backend instance that can be used to instantiate an decoder.

Trait Implementations

impl DecoderBackend for LibvdaDecoder

type Session = VdaDecoderSession

fn new_session(&mut self, format: Format) -> Result<Self::Session, VideoError>

Create a new decoding session for the passed format.

fn get_capabilities(&self) -> Capability

Return the decoding capabilities for this backend instance.

fn into_trait_object( self ) -> Box<dyn DecoderBackend<Session = Box<dyn DecoderSession>>>

where Self: Sized + 'static,

Turn this backend into a trait object, allowing the same decoder to operate on a set of different backends.
