Python, modify vcsi to ignore errors

Im using the following script in wrote in python: [login to view URL] (it creates video contact sheets). I'm running it in a "bash .sh" script. However if it fails the script stops. I would like to have either in the bash script line (see below) to ignore the error. If not able to do this via the bash line, slight modification of the "vcsi" script may be required. Here are the bash lines used to call the script: function make_thumbnails() { vcsi /var/www/clients/client1/web1/web/videos/*.mp4 -t -w 1800 -g 10x3 --background-color 000000 --metadata-font-color ffffff; echo -e "Thumbnails has been generated, please delete any unwanted thumbnail files and once finished, please run: $0 finalize" } Users have a request to add an "ignore errors" feature into VCSI, however it has not been added yet, see link below... I need it added to ignore errors.... [login to view URL] I have tried to add a few different bash version lines to igmore the error without getting satisfactory results. Shouldn't be difficult, please bid accordingly.
