 This is because ffmpeg applies an euristics for "normalizing" the input
 You can use the -copyts option for disabling such behavior.

 At this point you may note that the timestamp values will still be
 different from the ffprobe -show_packets output, although the time values
 are equivalent, that's because ffmpeg.c rescales all the input timestamps
 to a timebase of 1/1000000.

 In conclusion, the observed behavior is the assumed ffmpeg behavior
 (although maybe counter-intuitive), tell us if you think there is some
 problem with it.
