Hi Steli, I use:
Debian 11.8 Dspace 7.6 FFMPEG 4.3.6-0+deb11u1 ImageMagick 6.9.11-60 The " VIDEO:/tmp/imthumb12321.tmp[100]" path refers to frame number 100. It's strange that a 20s. video is less than 20 frames... but, could it be the case? The "VIDEO:" prefix refers to the ImageMagick "explicit image format" option on input files (see https://imagemagick.org/script/command-line-processing.php#input), and the VIDEO type is specified in the supported file formats list (see https://imagemagick.org/script/formats.php#supported). Can you test with a different file, e.g., GMT20230623-074346-video.mp4 available at https://hdl.handle.net/11705/SEM/SEM024? That thumbnail has been generated using this filter. I can also test with your file directly if it's publicly available and/or if you feel comfortable with it.
