In Dolphin > Settings > Configure Dolphin > General > Previews, do you have a list entry for "Videos (ffmpegthumbs)"? If so, it it enabled?

Hmm, Firefox claims the video is corrupt. There seems to be something wrong with it. Do you have any videos that do play in Firefox but don't get previews in Dolphin?

Thanks! I talked to Kai and he said it was known that this was broken in git master, but I can confirm that it's fixed now with your file! \o/
