I am using FFmpeg to grab a single frame from and RTSP on a windows server.

ffmpeg -rtsp_transport tcp -i rtsp:// -f image2 -vframes 1

I Scheduled this task to run every X mins.  However, Each time it runs, it
overwrites the sunflower-0000000001.jpg each time.

How can I prevent it from overwriting a file if it already exists?
