Enum gstreamer::State

#[non_exhaustive]
pub enum State {
    VoidPending,
    Null,
    Ready,
    Paused,
    Playing,
    // some variants omitted
}

The possible states an element can be in. States can be changed using crate::prelude::ElementExt::set_state() and checked using [crate::prelude::ElementExt::get_state()].

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.

VoidPending

no pending state.

Null

the NULL state or initial state of an element.

Ready

the element is ready to go to PAUSED.

Paused

the element is PAUSED, it is ready to accept and process data. Sink elements however only accept one buffer and then block.

Playing

the element is PLAYING, the crate::Clock is running and the data is flowing.
