Experts,
I am capturing mp4 files since several years with an ION SPEED PRO
without any issues. I did not use the camera a while. Today I realized
that either W10 (tested different laptops) and even Linux ins not able
to play these files any more. Old ION files ( same device) still do work
properly on W10 and Linux.
ffprobe does return :

Any idea what causing this ?
I am not an ffmepg, play, probe expert. I used these packages to analyze
the problem.
My impression is the files are corrupted. On the other hand the Ion
still does take still images. I also tried HD and FHD, no difference.
Any idea, hint is appreciated :
Kind Regards
Matthias
