Thus, the codes can be used efficiently in program code as integers, as well as giving cues in binary data streams when inspected.

Compiler support

FourCC is written in big endian relative to the underlying ASCII character sequence, so that it appears in the correct byte order when read as a string. Many C compilers, including GCC, define a multi-character literal behavior of right-aligning to the least significant byte, so that becomes 0x31323334 in
