Struct VaapiDecoder

pub struct VaapiDecoder {
    caps: Capability,
}

A safe decoder abstraction over libva for a single vaContext

Fields

caps: Capability

The capabilities for the decoder

Implementations

impl VaapiDecoder

fn get_coded_cap(display: &Display, profile: Type) -> Result<CodedCap>

fn get_raw_caps( display: Rc<Display>, coded_cap: &CodedCap, ) -> Result<Vec<RawCap>>

pub fn new() -> Result<Self>

Creates a new instance of the Vaapi decoder.

Trait Implementations

impl DecoderBackend for VaapiDecoder

type Session = VaapiDecoderSession

fn get_capabilities(&self) -> Capability

Return the decoding capabilities for this backend instance.

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

Create a new decoding session for the passed format.

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.
