Function Documentation

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

Decode a base64-encoded string.

Parameters

out	buffer for decoded data
in	null-terminated input string
out_size	size in bytes of the out buffer, must be at least 3/4 of the length of in

Returns

number of bytes written, or a negative value in case of invalid input

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

Encode data to base64 and null-terminate.

Parameters

out	buffer for encoded data
out_size	size in bytes of the out buffer (including the null terminator), must be at least AV_BASE64_SIZE(in_size)
in	input buffer containing the data to encode
in_size	size in bytes of the in buffer

Returns

out or NULL in case of error
