13            u_int32_t dataSize
14       )

DESCRIPTION

27       MP4BinaryToBase64 converts binary data to a base 64 string. This encod‐
28       ing  maps  groups  of 6 bits into the character set [A-Za-z0-9+/=]. The
29       string is in malloc'd memory, so the caller is responsible for free'ing
30       the memory.
31
32       This utility is useful for generating the SDP descriptions for some RTP
33       payloads.

35       Example:      0x12, 0xAB -> "Eqs="
