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.

source§

fn borrow(&self) -> &T

Immutably 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.
source§

impl<T> From<T> for T

source§

fn from(t: T) -> T

Returns the argument unchanged.

source§

impl<T, U> Into<U> for T
where U: From<T>,

source§

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

source§

impl<T, U> TryFrom<U> for T
where U: Into<T>,

§

type Error = Infallible

type Error = <U as TryFrom<T>>::Error

The type returned in the event of a conversion error.
source§

fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>

Performs the conversion.
