AudioConverter

This object is used to convert audio samples from one format to another. The object can perform conversion of:

audio format with optional dithering and noise shaping
audio samplerate
audio channels and channel layout

class AudioConverter : Boxed {

this(gstaudio.types.AudioConverterFlags flags, gstaudio.audio_info.AudioInfo inInfo, gstaudio.audio_info.AudioInfo outInfo, gst.structure.Structure config);

bool convert(gstaudio.types.AudioConverterFlags flags, ubyte[] in_, ubyte[] out_);

gst.structure.Structure getConfig(int inRate, int outRate);

size_t getInFrames(size_t outFrames);

size_t getMaxLatency();

size_t getOutFrames(size_t inFrames);

bool isPassthrough();

void reset();

bool supportsInplace();

bool updateConfig(int inRate, int outRate, gst.structure.Structure config);

}

Constructors

this this(gstaudio.types.AudioConverterFlags flags, gstaudio.audio_info.AudioInfo inInfo, gstaudio.audio_info.AudioInfo outInfo, gst.structure.Structure config): Create a new #GstAudioConverter that is able to convert between in and out audio formats.

Functions

convert bool convert(gstaudio.types.AudioConverterFlags flags, ubyte[] in_, ubyte[] out_): Convenience wrapper around gstaudio.audio_converter.AudioConverter.samples, which will perform allocation of the output buffer based on the result from gstaudio.audio_converter.AudioConverter.getOutFrames.
getConfig gst.structure.Structure getConfig(int inRate, int outRate): Get the current configuration of convert.
getInFrames size_t getInFrames(size_t outFrames): Calculate how many input frames are currently needed by convert to produce out_frames of output frames.
getMaxLatency size_t getMaxLatency(): Get the maximum number of input frames that the converter would need before producing output.
getOutFrames size_t getOutFrames(size_t inFrames): Calculate how many output frames can be produced when in_frames input frames are given to convert.
isPassthrough bool isPassthrough(): Returns whether the audio converter will operate in passthrough mode. The return value would be typically input to gstbase.base_transform.BaseTransform.setPassthrough
reset void reset(): Reset convert to the state it was when it was first created, clearing any history it might currently have.
supportsInplace bool supportsInplace(): Returns whether the audio converter can perform the conversion in-place. The return value would be typically input to gstbase.base_transform.BaseTransform.setInPlace
updateConfig bool updateConfig(int inRate, int outRate, gst.structure.Structure config): Set in_rate, out_rate and config as extra configuration for convert.

Inherited Members

From Boxed

cInstancePtr void* cInstancePtr;: Pointer to the C boxed value
getType GType getType(): Get the GType of this boxed type.
gType GType gType [@property getter]: Boxed GType property.
self Boxed self(): Convenience method to return this cast to a type. For use in D with statements.
copy_ void* copy_(): Make a copy of the wrapped C boxed data.
boxedCopy void* boxedCopy(void* cBoxed): Copy a C boxed value using g_boxed_copy.
boxedFree void boxedFree(void* cBoxed): Free a C boxed value using g_boxed_free.
