Struct EncoderQuality 

pub struct EncoderQuality {
    pub last: Option<u32>,
    pub bytes: Option<usize>,
    pub holds: bool,
    pub reopens: bool,
    pub keys: bool,
    pub band: Option<usize>,
    pub measures: bool,
    pub psnr: Option<f32>,
}

What an encoder says about the frames it codes, which the cleanup reads: the quality index its rate control last coded a frame at, where it reports one (FrameEncoder::last_quality), the bytes of that frame, where it reports them too (FrameEncoder::last_size), whether it holds a frame at a quantizer it is asked for (FrameEncoder::holds_quantizer), whether a change of its constant quality re-opens it on a key frame (FrameEncoder::reopens_on_quality), whether its constant-rate cleanup ends on a key frame (FrameEncoder::cleans_up_with_key), where it holds a band of a frame at that quantizer (FrameEncoder::band_size), the bytes of its last held frame, and, where it measures a frame’s reconstruction against its source when asked (FrameEncoder::measures), the last measurement.

Implementations

impl EncoderQuality

pub fn of(encoder: &FrameEncoder) -> Self

What encoder says.

pub fn converges(&self) -> bool

Whether a constant-rate cleanup runs through this encoder’s rate control: it says the bytes of its frames, so the cleanup can tell when the rate control has stopped refining a still screen, and with their quantizer whether that is at the paint-over quality.
