AudioStreamAlign

#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.

class AudioStreamAlign : Boxed {

this(int rate, gst.types.ClockTime alignmentThreshold, gst.types.ClockTime discontWait);

gstaudio.audio_stream_align.AudioStreamAlign copy();

gst.types.ClockTime getAlignmentThreshold();

gst.types.ClockTime getDiscontWait();

int getRate();

ulong getSamplesSinceDiscont();

gst.types.ClockTime getTimestampAtDiscont();

void markDiscont();

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

void setAlignmentThreshold(gst.types.ClockTime alignmentThreshold);

void setDiscontWait(gst.types.ClockTime discontWait);

void setRate(int rate);

}

Constructors

this 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 new rate. A negative rate can be used for reverse playback.

Functions

copy gstaudio.audio_stream_align.AudioStreamAlign copy(): Copy a GstAudioStreamAlign structure.
getAlignmentThreshold gst.types.ClockTime getAlignmentThreshold(): Gets the currently configured alignment threshold.
getDiscontWait gst.types.ClockTime getDiscontWait(): Gets the currently configured discont wait.
getRate int getRate(): Gets the currently configured sample rate.
getSamplesSinceDiscont ulong getSamplesSinceDiscont(): Returns the number of samples that were processed since the last discontinuity was detected.
getTimestampAtDiscont gst.types.ClockTime getTimestampAtDiscont(): Timestamp that was passed when a discontinuity was detected, i.e. the first timestamp after the discontinuity.
markDiscont void markDiscont(): Marks the next buffer as discontinuous and resets timestamp tracking.
process bool process(bool discont, gst.types.ClockTime timestamp, uint nSamples, gst.types.ClockTime outTimestamp, gst.types.ClockTime outDuration, ulong outSamplePosition): Processes 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-discontinuous data will have perfect timestamps and durations.
setAlignmentThreshold void setAlignmentThreshold(gst.types.ClockTime alignmentThreshold): Sets alignment_treshold as new alignment threshold for the following processing.
setDiscontWait void setDiscontWait(gst.types.ClockTime discontWait): Sets alignment_treshold as new discont wait for the following processing.
setRate void setRate(int rate): Sets rate as new sample rate for the following processing. If the sample rate differs this implicitly marks the next data as discontinuous.

Inherited Members
