If the file name (%F) starts with a “-” character, the file is not found by ffprobe.exe (the file name from the next character after “-” is passed to ffprobe).

How to save this correctly?

for /f %%i in ('ffprobe -v error -select_streams v:0 -show_entries stream^=height -of csv^=s^=x:p^=0 "%%F"') do set hgt=%%i

I expected the full file name to be passed to ffprobe.exe, e.g. “- 7.06.2022.mpg”
