NAMEMP4BinaryToBase16 − Convert binary data to a base 16 string

---

SYNTAX#include <mp4.h> char* MP4BinaryToBase16(
const u_int8_t* pData,
u_int32_t dataSize
)

---

ARGUMENTSpData  Specifies the pointer to the binary data. dataSize  Specifies the size in bytes of the binary data.

---

RETURN VALUESUpon success, a null terminated string representing the data in base 16. Upon error, NULL.

---

DESCRIPTIONMP4BinaryToBase16 converts binary data to a base 16 string. This encoding maps groups of 4 bits into the character set [0−9a−f]. The string is in malloc'd memory, so the caller is responsible for free'ing the memory. This utility is useful for generating the SDP descriptions for some RTP payloads. Example: 0x12, 0xAB −> "12ab"
