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

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)
