Function Documentation

int av_base64_decode	(	uint8_t *	out,
		const char *	in,
		int	out_size
	)

Decodes the base64-encoded string in in and puts the decoded data in out.

Parameters:

out_size

size in bytes of the out buffer, it should be at least 3/4 of the length of in

Returns:

the number of bytes written, or a negative value in case of error

char* av_base64_encode	(	char *	out,
		int	out_size,
		const uint8_t *	in,
		int	in_size
	)

Encodes in base64 the data in in and puts the resulting string in out.

Parameters:

	out_size	size in bytes of the out string, it should be at least ((in_size + 2) / 3) * 4 + 1
	in_size	size in bytes of the in buffer

Returns:

the string containing the encoded data, or NULL in case of error
