Hello all, Thanks Abel for the solution to the issue with the PDF files. Unfortunately, the problem with the mp4 files persists. It says the script is running, but the mp4 thumbnail is never produced, and no error is created. I tried changing VIDEO to MPEG on line 66 of DSpace/dspace-api/src/main/java/org/dspace/app/mediafilter/ImageMagickVideoThumbnailFilter.java, and it made no difference. I've doublechecked the configuration settings ( https://wiki.lyrasis.org/display/DSDOC7x/ImageMagick+Media+Filters). Nothing seems to work. Does anyone have any other suggestions? Abel, which version of DSpace are you running, if you don't mind me asking?
Thanks, Carolyn.
