uppercase *.JPG => wrong command for avconv
I recorded series of images with the nintendo, resulting in a sequence of images ending in .....JPG.
When assembling these in StopMotion, the export to video file (Ctrl-Alt-V) command resulted in an error:
avconv version 9.16-6:
built on Aug 10 2014 18:19:26 with gcc 4.8 (Ubuntu 4.8.2-19ubuntu1)
Indeed, the said directory contains files ending in .JPG (uppercase). Manually executing above command with lowercase .jpg does produce a video.
