Expand description

Outcome of the full-frame send decision produced by decide_hw_fullframe.

Fields§

§send: bool§force_idr: bool§target_qp: u32

The session quality index the frame is encoded at.

§hold_qp: Option<u32>

The quality index this frame is held at whatever the rate control: the cleanup of a still screen, handed to the encoder’s hold_quantizer.

§hold_band: Option<(f64, f64)>

The share of the picture, from and to in raster order, hold_qp covers, the rest of the frame held at the coarsest quantizer; None for the whole picture.

§measure: bool

Whether the encoder is asked to measure this frame’s reconstruction (FrameEncoder::measure).

Implementations§

Source §

impl HwFrameDecision

Source

pub fn prepare(&self, encoder: &mut FrameEncoder)

Tell encoder what the decision asks of the frame it is about to code: the quantizer it is held at and whether its reconstruction is measured.

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.
