Auto-rename by ffmpeg if output file exists?

[pxstein]

When I perform a video conversion with ffmpeg and the output file already existing then the user is prompted if the existing video should be overwritten.

Can I somehow specify that the new (or old) video file is automatically renamed in this case?

e.g. to

<basevideoname>_<timestamp>.<extension>
or
<basevideoname>_new3.<extension>

Thank you
Peter

Not just with ffmpeg.

But if you use it together in a windows batch can you make something like http://stackoverflow.com/questions/17387072/using-command-prompt-batch-files-to-move-a...duplicate-file (the first answer). Instead of move you run the ffmpeg command with the new filename.
