Comment:

 These NAL units are not irrelevant to the frame; they are part of the
 access unit that the IDR slice belongs to. (Access unit is also what
 FFmpeg puts into one packet and what most containers expect (although it
 is also supported to have a pair of field pictures in one packet (as is
 common in mpegts)); read the H.264 spec if you want to know how access
 units are delimited.)
