Comment (by cehoyos):

 Replying to [comment:12 jsteinkamp]:
 > HI I have figured out the issue: ffmpeg compresses Photo JPEG with
 yuvj444p 24 bit by default.

 This is not correct (it depends on the input file).

 > This compression does not play well on any computers since it uses
 software to decode.

 This sounds wrong.

 But didn’t we already solve this mystery above?
