ConsumptionLink

gstreamer_utils::streamproducer

Struct ConsumptionLink 

Source 
pub struct ConsumptionLink { /* private fields */ }
Expand description

Link between a StreamProducer and a consumer, disconnecting the link on Drop. The producer and consumer will stay alive while the link is.

Implementations§

Source

pub fn disconnected(consumer: AppSrc) -> ConsumptionLink

Create a new disconnected ConsumptionLink.

The consumer will use the default configuration (see StreamProducer::configure_consumer). If you need different settings, call ConsumptionLink::disconnected_with instead.

Source

pub fn disconnected_with( consumer: AppSrc, settings: ConsumerSettings, ) -> ConsumptionLink

Create a new disconnected ConsumptionLink.

Source

pub fn change_producer( &mut self, new_producer: &StreamProducer, reset_stats: bool, ) -> Result<(), AddConsumerError>

Replace the producer by a new one, keeping the existing consumer.

Source

pub fn disconnect(&mut self)

Disconnect the consumer from the producer

Source

pub fn dropped(&self) -> u64

number of dropped buffers because the consumer internal queue was full

Source

pub fn pushed(&self) -> u64

number of buffers pushed through this link

Source

pub fn discard(&self) -> bool

if buffers are currently pushed through this link

Source

pub fn set_discard(&self, discard: bool)

If set to true then no buffers will be pushed through this link

Source

pub fn wait_for_keyframe(&self) -> bool

if the link will drop frames until the next keyframe on discont

Source

pub fn set_wait_for_keyframe(&self, wait: bool)

If set to true then the link will drop delta-frames until the next keyframe on discont (default behavior).

Source

pub fn appsrc(&self) -> &AppSrc

Get the GStreamer appsrc wrapped by this link

Source

pub fn stream_producer(&self) -> Option<&StreamProducer>

Get the StreamProducer currently by this link, if any.

Source

pub fn settings(&self) -> ConsumerSettings

Get the settings for this Consumer.
