ok, this works fine and now I can see the console window and close it 
when the video has ended.

This didn't work in my test. The FFplay window remains open and shows 
the last frame, until I manually close the FFmpeg console window. 
Pressing "q" or "esc" to close the FFplay window does only work if the 
video is still running, but not if the video has already ended.

I've written a summary into my book in chapter 3.16 (but chapter 
numbering may change in future):

Thanks for your help,
