Function Documentation

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

Parameters
outbuffer for decoded data
innull-terminated input string
out_sizesize 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
outbuffer for encoded data
out_sizesize in bytes of the out buffer (including the null terminator), must be at least AV_BASE64_SIZE(in_size)
ininput buffer containing the data to encode
in_sizesize in bytes of the in buffer
Returns
out or NULL in case of error
