You indeed have a problem. Thunar runs thumbnailers with the following
args: infile outfile size

I just tested on my box (trying to have it output the complete command)
and it works fine:

ffmpegthumbnailer -i /tmpinfile.avi -o /tmp/.thunar-vfs-thumbnail.K2SQSV
-s 128 -f -t 15

-i -i looks suspicious, and -o /home is definitely wrong. Are you sure
this is the output of a valid Thunar run of ffmpeg-thumbnailer?

Could you paste the output of:

strings .cache/Thunar/thumbnailers.cache
