Use ffmpeg from Crontab not working

Hallo,

the following example script works fine on shell. But not from cron.

#!/bin/sh
/storage/.kodi/addons/tools.ffmpeg-tools/bin/ffmpeg -i /storage/videos/ts.mp4 /storage/videos/ts.mkv

/storage/.kodi/addons/tools.ffmpeg-tools/bin/ffmpeg: error while loading shared libraries: libgnutls.so.30: cannot open shared object file: No such file or directory

Can anybody help me?

Thank you very much.
