Comment (by cehoyos):

 If I understand correctly, you see two different (and indpendent) issues:
 One is that the FFmpeg mov muxer only outputs constant frame rate, so if
 FFmpeg interprets your input file as variable frame rate, it will insert
 frames to achieve constant frame rate. This is reported in several
 tickets.
 {{{-vsync 0}}} avoids frame duplications, it may brake A/V sync but to
 test the bitexactness of your encodings, it is useful.

 I am unable to reproduce a difference between the original frames and the
 frames encoded with openjpeg-1.5.0-2.7.1.x86_64:

 {{{-f framecrc}}} is also identical for both files here (apart from the
 timestamp issue).

 Could this be an issue with your openjpeg version (or compilation)?
