Enum gstreamer::QOSType

#[non_exhaustive]
pub enum QOSType {
    Overflow,
    Underflow,
    Throttle,
    // some variants omitted
}

The different types of QoS events that can be given to the [crate::Event::new_qos()] method.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Overflow

The QoS event type that is produced when upstream elements are producing data too quickly and the element can’t keep up processing the data. Upstream should reduce their production rate. This type is also used when buffers arrive early or in time.

Underflow

The QoS event type that is produced when upstream elements are producing data too slowly and need to speed up their production rate.

Throttle

The QoS event type that is produced when the application enabled throttling to limit the data rate.
