 It is possible (and was done by a user) to concatenate jpeg 2000 frames:
 {{{
 $ ffmpeg -f lavfi -i testsrc=r=1:d=5 -vcodec jpeg2000 -f rawvideo out.j2m
 }}}
 The resulting output file cannot be decoded except for the first frame
 because no jpeg 2000 parser exists:
 {{{
 $ ffmpeg -i out.j2m -f null -
