Function Documentation

G_GNUC_MALLOC const void* pcm_byteswap	(	struct pcm_buffer *	buffer,
		enum sample_format	format,
		const void *	src,
		size_t	size
	)

Changes the endianness of PCM data.

Parameters:

buffer	the destination pcm_buffer object
format	the sample format (both input and output)
src	the source PCM buffer
src_size	the number of bytes in #src

Returns:

the destination buffer, or NULL if the sample format is not supported

const int16_t* pcm_byteswap_16	(	struct pcm_buffer *	buffer,
		const int16_t *	src,
		size_t	len
	)

Changes the endianness of 16 bit PCM data.

Parameters:

buffer	the destination pcm_buffer object
src	the source PCM buffer
src_size	the number of bytes in #src

Returns:

the destination buffer

const int32_t* pcm_byteswap_32	(	struct pcm_buffer *	buffer,
		const int32_t *	src,
		size_t	len
	)

Changes the endianness of 32-bit (or 24-bit) PCM data.

Parameters:

buffer	the destination pcm_buffer object
src	the source PCM buffer
src_size	the number of bytes in #src

Returns:

the destination buffer
