Struct gstreamer_audio::AudioBaseSink [−][src]
pub struct AudioBaseSink(_);
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.
Implements
AudioBaseSinkExt, gst_base::prelude::BaseSinkExt, gst::prelude::ElementExt, gst::prelude::GstObjectExt, glib::ObjectExt

Blanket Implementations
Get the number of bytes that the sink will pull when it is operating in pull mode. Read more
v1_12 only.Checks if self is currently configured to drop buffers which are outside
the current segment Read more
Get the last sample that arrived in the sink and was used for preroll or for rendering. This property can be used to generate thumbnails. Read more
Get the maximum amount of bits per second that the sink will render. Read more
Gets the max lateness value. See set_max_lateness() for
more details. Read more
v1_16 only.Get the processing deadline of self. see
set_processing_deadline() for more information about
the processing deadline. Read more
Get the render delay of self. see set_render_delay() for more
information about the render delay. Read more
v1_18 only.Return various BaseSink statistics. This function returns a gst::Structure
with name application/x-gst-base-sink-stats with the following fields: Read more
Checks if self is currently configured to synchronize against the
clock. Read more
Get the time that will be inserted between frames to control the maximum buffers per second. Read more
Set the number of bytes that the sink will pull when it is operating in pull mode. Read more
v1_12 only.Configure self to drop buffers which are outside the current segment Read more
Set the maximum amount of bits per second that the sink will render. Read more
Sets the new max lateness value to max_lateness. This value is
used to decide if a buffer should be dropped or not based on the
buffer timestamp and the current clock time. A value of -1 means
an unlimited time. Read more
v1_16 only.Maximum amount of time (in nanoseconds) that the pipeline can take for processing the buffer. This is added to the latency of live pipelines. Read more
Set the render delay in self to delay. The render delay is the time
between actual rendering of a buffer and its synchronisation time. Some
devices might delay media rendering which can be compensated for with this
function. Read more
Set the time that will be inserted between rendered buffers. This can be used to control the maximum buffers per second that the sink will render. Read more
Adjust the synchronisation of self with offset. A negative value will
render buffers earlier than their timestamp. A positive value will delay
rendering. This function can be used to fix playback of badly timestamped
buffers. Read more
This function will wait for preroll to complete and will then block until time
is reached. It is usually called by subclasses that use their own internal
synchronisation but want to let some synchronization (like EOS) be handled
by the base class. Read more
