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.
