.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.
