AudioBuffer

A structure containing the result of an audio buffer map operation, which is executed with gstaudio.audio_buffer.AudioBuffer.map. For non-interleaved (planar) buffers, the beginning of each channel in the buffer has its own pointer in the @planes array. For interleaved buffers, the @planes array only contains one item, which is the pointer to the beginning of the buffer, and @n_planes equals 1.

The different channels in @planes are always in the GStreamer channel order.

class AudioBuffer {

GstAudioBuffer cInstance;

void unmap();

static gst.buffer.Buffer clip(gst.buffer.Buffer buffer, gst.segment.Segment segment, int rate, int bpf);

static bool map(gstaudio.audio_buffer.AudioBuffer buffer, gstaudio.audio_info.AudioInfo info, gst.buffer.Buffer gstbuffer, gst.types.MapFlags flags);

static bool reorderChannels(gst.buffer.Buffer buffer, gstaudio.types.AudioFormat format, gstaudio.types.AudioChannelPosition[] from, gstaudio.types.AudioChannelPosition[] to);

static gst.buffer.Buffer truncate(gst.buffer.Buffer buffer, int bpf, size_t trim, size_t samples);

}

Functions

unmap void unmap(): Unmaps an audio buffer that was previously mapped with gstaudio.audio_buffer.AudioBuffer.map.

Static functions

clip gst.buffer.Buffer clip(gst.buffer.Buffer buffer, gst.segment.Segment segment, int rate, int bpf): Clip the buffer to the given gst.segment.Segment.
map bool map(gstaudio.audio_buffer.AudioBuffer buffer, gstaudio.audio_info.AudioInfo info, gst.buffer.Buffer gstbuffer, gst.types.MapFlags flags): Maps an audio gstbuffer so that it can be read or written and stores the result of the map operation in buffer.
reorderChannels bool reorderChannels(gst.buffer.Buffer buffer, gstaudio.types.AudioFormat format, gstaudio.types.AudioChannelPosition[] from, gstaudio.types.AudioChannelPosition[] to): Reorders buffer from the channel positions from to the channel positions to. from and to must contain the same number of positions and the same positions, only in a different order. buffer must be writable.
truncate gst.buffer.Buffer truncate(gst.buffer.Buffer buffer, int bpf, size_t trim, size_t samples): Truncate the buffer to finally have samples number of samples, removing the necessary amount of samples from the end and trim number of samples from the beginning.
