Thank you, that worked straight away, ffprobe is installed on my systems already and I can probably just grep for the tag I want as all I'm looking for is the date of its creation which appears (twice) with the tag "creation_time". This is just to handle the occasional MP4 that a python program which basically manages JPEGs can't handle. It throws an exception so I can just get that to run a simple bash script to get the creation date. -- Chris Green ยท -- https://mail.python.org/mailman/listinfo/python-list
