Comment (by AlexSmith):

 I see your command line specifies output as this:


 It may be a typo, but the correct pattern should be this:


 By inspecting the
 source code], you can see, at line 99, ffmpeg uses strftime() from the
 system's time.h, so, unless you have a problem with your system libs, it
 should work just fine.

 I don't have a Windows box to test it, but in Linux, this command line:

 ffmpeg -nostdin -loglevel debug -f v4l2 -r 1 -i /dev/video0 -f image2
 -strftime 1 -y "/tmp/%Y%m%d%H%M%S%z.jpg"

 generates this output files:

 [image2 @ 0x555557c49b40] Opening '/tmp/20191218000441+0000.jpg' for
 [file @ 0x555557cfadc0] Setting default whitelist 'file,crypto'

 I'm using the latest git version.
