Comment (by Balling):

 The warnings are because of garbage in the end! Indeed see ffprobe.exe
 -show_frames -v debug j2k1.j2c it warns on second frame or what it thinks
 is a second frame.

 As to whether it should read past the 0xFFD9, after all cannot it have
 multiple images in one j2c?

 I will also point out that two encoded with two Kakadu versions are the
 same, except for some stuff after 0xFFD9 where should be nothing anyway.

 I also showed that the our jpeg2000 decoder is better, BTW.
