Thanks for not showing us YOUR complete console output. You do realize
that it contains information which may help in identifying issues? So I
won't show mine, which could help (you) with comparing.


Sorry about that. Must be frustrating. Here is my output:

I will tell you though that it "works for me" with latest ffmpeg. This
is what VLC says before playing very smoothly:
