If you want to extract more than one picture, then the output filename
should contain a number that's automatically increased.
For example:

ffmpeg -i rtsp://192.168.9.78:5004 -t 5 -y test%4d.jpg

%4d is a 4-digit number that's automatically increased.
If you are starting FFmpeg from a Windows batch file, then % must be
replaced by %%
-t 5 does limit the duration to 5 seconds.
-y does automatically overwrite the output files, if they exist already.

It's working as expected, Thanks a lot for your support, Michael!

Regards,
