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"
