| \fIpData\fP |
| Specifies the pointer to the binary data. |
| .TP |
| \fIdataSize\fP |
| Specifies the size in bytes of the binary data. |
| .SH "RETURN VALUES" |
| .LP |
| Upon success, a null terminated string representing the data in base 64. Upon error, NULL. |
| .SH "DESCRIPTION" |
| .LP |
| \fBMP4BinaryToBase64\fR converts binary data to a base 64 string. This encoding maps groups of 6 bits into the character set [A\-Za\-z0\-9+/=]. The string is in malloc'd memory, so the caller is responsible for free'ing the memory. |
| .LP |
| This utility is useful for generating the SDP descriptions for some RTP payloads. |
