public struct Buffer

A structure containing the result of an audio buffer map operation, which is executed with 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.

Namespace: Gst.Audio

Package: gstreamer-audio-1.0

Content:

Static methods:

public static Buffer clip (owned Buffer buffer, Segment segment, int rate, int bpf)
Clip the buffer to the given Segment.
public static bool reorder_channels (Buffer buffer, Format format, ChannelPosition[] from, ChannelPosition[] to)
Reorders buffer from the channel positions from to the channel positions to.
public static Buffer truncate (owned 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.

Methods:

public bool map (Info info, Buffer gstbuffer, MapFlags flags)
Maps an audio gstbuffer so that it can be read or written and stores the result of the map operation in buffer.
public void unmap ()
Unmaps an audio buffer that was previously mapped with map.

Fields:

public unowned Info info
public size_t n_samples
public int n_planes
public void* planes
