12            const u_int8_t* pData,
13            u_int32_t dataSize
14       )

DESCRIPTION

27       MP4BinaryToBase16 converts binary data to a base 16 string. This encod‐
28       ing  maps  groups of 4 bits into the character set [0-9a-f]. The string
29       is in malloc'd memory, so the caller is responsible  for  free'ing  the
30       memory.
31
32       This utility is useful for generating the SDP descriptions for some RTP
33       payloads.
34
35       Example:      0x12, 0xAB -> "12ab"
