NAME

MP4BinaryToBase16 - Convert binary data to a base 16 string

SYNTAX

#include <mp4.h>

char* MP4BinaryToBase16(
       const u_int8_t* pData,

       u_int32_t dataSize

)

ARGUMENTS

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

RETURN VALUES

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

DESCRIPTION

MP4BinaryToBase16 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"
