--- Comment #24 from caulier.gil...@gmail.com --- I tested here using samples from http://www.sample-videos.com/ Mp4 and 3GP preview work fine. Other format, no. I'm sure that it's a missing codec problem installed on the system and used by Qt5Multimedia (same problem than under Windows). The preview doesn't work at all (idem than Windows probably).
