No video thumnails xfce/thunar

I am using 64 bit 42.1/XFCE/Thunar fully updated.

Video thumnails are not being generated. I have installed all the codecs I could find. I have installed ffmpeg and ffmpreg thumbs and thumnailer. I removed previous thumbnails. I created another user account to see if video thumbs would be generated there. They were not.

I installed. pcmanfm. It generated the video thumbnails and Thunar could see them, but still not create them.

Does anyone have any solutions to fix this?
