Comment (by cehoyos):

 I am not a native speaker either, I am a bit unhappy if people asking for
 support write "I will test your suggestion if, when and after..."

 I cannot really answer your other questions: At least one of your input
 jpg images (no, I am not interested to go through the huge file you
 attached again, so I don't know the name) does not define a DPI resolution
 which is the aspect ratio of the image from FFmpeg's pov. If the input
 stream does not specify an aspect ratio and the user does not specify an
 aspect ratio, an output h264 stream will not have an aspect ratio set. I
 believe this behaviour makes sense and should not be changed.

 It is of course possible that I completely misunderstand the issue but you
 will have to add information if you think that I am wrong.
