gstaudio.audio_stream_align

Module for [AudioStreamAlign] class

Types 1

classAudioStreamAlign : gobject.boxed.Boxed

#GstAudioStreamAlign provides a helper object that helps tracking audio stream alignment and discontinuities, and detects discontinuities if possible.

See gstaudio.audio_stream_align.AudioStreamAlign.new_ for a description of its parameters and gstaudio.audio_stream_align.AudioStreamAlign.process for the details of the processing.

Methods

void * _cPtr(Flag!"Dup" dup = No.Dup) nothrow

GType _getGType() static nothrow

GType _gType() @property nothrow

AudioStreamAlign self() nothrowReturns `this`, for use in `with` statements.

gstaudio.audio_stream_align.AudioStreamAlign copy() nothrowCopy a GstAudioStreamAlign structure. Returns: a new #GstAudioStreamAlign. free with gst_audio_stream_align_free.

gst.types.ClockTime getAlignmentThreshold() nothrowGets the currently configured alignment threshold. Returns: The currently configured alignment threshold

gst.types.ClockTime getDiscontWait() nothrowGets the currently configured discont wait. Returns: The currently configured discont wait

int getRate() nothrowGets the currently configured sample rate. Returns: The currently configured sample rate

ulong getSamplesSinceDiscont() nothrowReturns the number of samples that were processed since the last discontinuity was detected. Returns: The number of samples processed since the last discontinuity.

gst.types.ClockTime getTimestampAtDiscont() nothrowTimestamp that was passed when a discontinuity was detected, i.e. the first timestamp after the discontinuity. Returns: The last timestamp at when a discontinuity was detected

void markDiscont() nothrowMarks the next buffer as discontinuous and resets timestamp tracking.

bool process(bool  discont,  gst.types.ClockTime timestamp,  uint  nSamples,  out  gst.types.ClockTime outTimestamp,  out  gst.types.ClockTime outDuration,  out  ulong  outSamplePosition)

nothrowProcesses data with timestamp and n_samples, and returns the output timestamp, duration and sample position together with a boolean to signal whether a discontinuity was detected or not. All non-di...

void setAlignmentThreshold(gst.types.ClockTime alignmentThreshold) nothrowSets alignment_treshold as new alignment threshold for the following processing.

void setDiscontWait(gst.types.ClockTime discontWait) nothrowSets alignment_treshold as new discont wait for the following processing.

void setRate(int rate) nothrowSets rate as new sample rate for the following processing. If the sample rate differs this implicitly marks the next data as discontinuous.

Constructors

this(void * ptr, Flag!"Take" take)

this(int rate, gst.types.ClockTime alignmentThreshold, gst.types.ClockTime discontWait)Allocate a new #GstAudioStreamAlign with the given configuration. All processing happens according to sample rate rate, until [gstaudio.audio_stream_align.AudioStreamAlign.setRate] is called with a...
