frame_code
the meaning of this byte is stored in the main header
frame_code is a 8bit field which exists before every frame, it can
store part of the size of the frame, the stream number, the timestamp
and some flags amongth other things, what is not directly stored
in it but is needed is stored in various fields immedeatly after it
the values stored in it can be found in the main header
the value 78 ('N') is forbidden to ensure that the byte is always
different from the first byte of any startcode
a muxer SHOULD mark 0x00 and 0xFF as invalid to improve error
