• Timestamp not printed on thumbnails with FFMPEG

  26 août 2021, par mlatelcom

  I have a script using FFMPEG to generate an image with tiled thumbnails every 45 seconds for several videos on a given folder. The images are named with the name of the video it was generated from. It generates the thumbnails for each video but it does not print the time stamps on them. The path to the font file is correct ; so I don't know where the issue is. I'm using the script in Fedora Linux.

  


  Here is the FFMPEG command line code on the script :

  


   ffmpeg -ss 00:00:05 -i test.mp4 -loglevel 40 -frames 1 -bt 20M -vf "drawtext=fontfile=/usr/share/fonts/open-sans/OpenSans-Light.ttf:timecode='00\\:00\\:00\\:00':r=30:fontcolor=white:x=220:y=220:box=1:boxcolor=black@0.5,select=not(mod(n\,1350)),scale=200:150,tile=15x48" -n "${name}.png"


  


  and this is the console output
