Comment (by mucikiki):

 I try to concat test1.mp4 with themself, and to concat test2.mp4 with
 themself, and I check both videos with MediaInfo (to have a different
 point of view).

 With test1concat.mp4, the frame rate mode is still Costant, but with
 test2concat.mp4 is now Variable:

 Frame rate                               : 29.970 (29970/1000) FPS
 Minimum frame rate                       : 29.586 FPS
 Maximum frame rate                       : 29.970 FPS

 So I think this is an issue of the file.
