source ·

pub struct VaapiDecoder {
    caps: Capability,
}

Expand description

A safe decoder abstraction over libva for a single vaContext

Fields§

§caps: Capability

The capabilities for the decoder

Implementations§

source §

impl VaapiDecoder

source

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

source

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

source

pub fn new() -> Result<Self>

Creates a new instance of the Vaapi decoder.

Trait Implementations§

source §

impl DecoderBackend for VaapiDecoder

§

type Session = VaapiDecoderSession

source §

fn get_capabilities(&self) -> Capability

Return the decoding capabilities for this backend instance.

source §

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

Create a new decoding session for the passed format.

source §

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.

Blanket Implementations§

source §

impl<T> Any for T
where T: 'static + ?Sized,

source §

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

source §

impl<T> Borrow<T> for T
where T: ?Sized,

source §

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

source §

impl<T> BorrowMut<T> for T
where T: ?Sized,

source §

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

§

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

§

impl<T> DowncastSync for T
where T: Any + Send + Sync,

§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
