gstaudio.audio_info.AudioInfo newFromCaps(gst.caps.Caps caps)Parse caps to generate a #GstAudioInfo.

bool convert(gst.types.Format srcFmt, long srcVal, gst.types.Format destFmt, out long destVal)Converts among various #GstFormat types. This function handles GSTFORMATBYTES, GSTFORMATTIME, and GSTFORMATDEFAULT. For raw audio, GSTFORMATDEFAULT corresponds to audio frames. This function can...

bool isEqual(gstaudio.audio_info.AudioInfo other)Compares two #GstAudioInfo and returns whether they are equal or not

void setFormat(gstaudio.types.AudioFormat format,  int  rate,  int  channels,  gstaudio.types.AudioChannelPosition[]  position =  null)

Set the default info for the audio info of format and rate and channels.

gst.caps.Caps toCaps()Convert the values of info into a #GstCaps. Returns: the new #GstCaps containing the info of info.

bool fromCaps(out gstaudio.audio_info.AudioInfo info, gst.caps.Caps caps)Parse caps and update info.

void init_(out gstaudio.audio_info.AudioInfo info)Initialize info with default values.

Constructors

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

this()Allocate a new #GstAudioInfo that is also initialized with [gstaudio.audioinfo.AudioInfo.init]. Returns: a new #GstAudioInfo. free with [gstaudio.audio_info.AudioInfo.free].
