This module contains some helper functions for encapsulating various audio formats in IEC 61937 headers and padding.
guint gst_audio_iec61937_frame_size (const GstRingBufferSpec *spec);
Calculated the size of the buffer expected by gst_audio_iec61937_payload() for
payloading type from spec.
|
the ringbufer spec |
Returns : |
the size or 0 if the given type is not supported or cannot be
payloaded. |
Since 0.10.36
gboolean gst_audio_iec61937_payload (const guint8 *src,guint src_n,guint8 *dst,guint dst_n,const GstRingBufferSpec *spec);
Payloads src in the form specified by IEC 61937 for the type from spec and
stores the result in dst. src must contain exactly one frame of data and
the frame is not checked for errors.
|
a buffer containing the data to payload |
|
size of src in bytes |
|
the destination buffer to store the payloaded contents in. Should not
overlap with src
|
|
size of dst in bytes |
|

|
Returns : |
transfer-full: TRUE if the payloading was successful, FALSE
