Struct gstreamer_audio::AudioBaseSink
source · pub struct AudioBaseSink { /* private fields */ }Expand description
This is the base class for audio sinks. Subclasses need to implement the ::create_ringbuffer vmethod. This base class will then take care of writing samples to the ringbuffer, synchronisation, clipping and flushing.
§Properties
§alignment-threshold
Readable | Writeable
§buffer-time
Readable | Writeable
§can-activate-pull
Readable | Writeable
§discont-wait
A window of time in nanoseconds to wait before creating a discontinuity as a result of breaching the drift-tolerance.
Readable | Writeable
§drift-tolerance
Controls the amount of time in microseconds that clocks are allowed to drift before resynchronisation happens.
Readable | Writeable
§latency-time
Readable | Writeable
§provide-clock
Readable | Writeable
§slave-method
Readable | Writeable
BaseSink
§async
If set to true, the basesink will perform asynchronous state changes.
When set to false, the sink will not signal the parent when it prerolls.
Use this option when dealing with sparse streams or when synchronisation is
not required.
Readable | Writeable
§blocksize
The amount of bytes to pull when operating in pull mode.
Readable | Writeable
§enable-last-sample
Enable the last-sample property. If false, basesink doesn’t keep a
reference to the last buffer arrived and the last-sample property is always
set to None. This can be useful if you need buffers to be released as soon
as possible, eg. if you’re using a buffer pool.
Readable | Writeable
§last-sample
The last buffer that arrived in the sink and was used for preroll or for
rendering. This property can be used to generate thumbnails. This property
can be None when the sink has not yet received a buffer.
Readable
§max-bitrate
Control the maximum amount of bits that will be rendered per second. Setting this property to a value bigger than 0 will make the sink delay rendering of the buffers when it would exceed to max-bitrate.
Readable | Writeable
§max-lateness
Readable | Writeable
§processing-deadline
Maximum amount of time (in nanoseconds) that the pipeline can take for processing the buffer. This is added to the latency of live pipelines.
Readable | Writeable
§qos
Readable | Writeable
§render-delay
The additional delay between synchronisation and actual rendering of the media. This property will add additional latency to the device in order to make other sinks compensate for the delay.
Readable | Writeable
§stats
Various gst_base::BaseSink statistics. This property returns a GstStructure
with name application/x-gst-base-sink-stats with the following fields:
- “average-rate” G_TYPE_DOUBLE average frame rate
- “dropped” G_TYPE_UINT64 Number of dropped frames
- “rendered” G_TYPE_UINT64 Number of rendered frames
Readable
§sync
Readable | Writeable
§throttle-time
The time to insert between buffers. This property can be used to control the maximum amount of buffers per second to render. Setting this property to a value bigger than 0 will make the sink create THROTTLE QoS events.
Readable | Writeable
§ts-offset
Controls the final synchronisation, a negative value will render the buffer earlier while a positive value delays playback. This property can be used to fix synchronisation in bad files.
Readable | Writeable
Object
§name
Readable | Writeable | Construct
§parent
The parent of the object. Please note, that when changing the ‘parent’
property, we don’t emit notify and deep-notify
signals due to locking issues. In some cases one can use
GstBin::element-added or GstBin::element-removed signals on the parent to
achieve a similar effect.
Readable | Writeable
