enum SessionState {

Expand description

A crosvm decoder needs to go through a number if setup stages before being able to decode, and can require some setup to be redone when a dynamic resolution change occurs. This enum ensures that the data associated with a given state only exists when we actually are in this state.

Variants§

§

AwaitingInitialResolution

Waiting for libavcodec to tell us the resolution of the stream.

§

AwaitingBufferCount

Waiting for the client to call set_output_buffer_count.

§

Decoding

Fields

§output_queue: OutputQueue
§format_converter: SwConverter

Decoding and producing frames.

§

Drc

Dynamic Resolution Change - we can still accept buffers in the old format, but are waiting for new parameters before doing any decoding.

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.
