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

Parameters:
out buffer for encoded data
out_size size in bytes of the output buffer, must be at least AV_BASE64_SIZE(in_size)
