--- Comment #19 from Weng Xuetian <wen...@gmail.com> ---
I just checked this on Archlinux.
The necessary package for me to get it working is ffmpegthumbs-21.04.0-1, and I
also need to manually enable it in doplhin. After that it just works.
Since the report is about opensuse and the only release provides 20.12 in
opensuse is tumbleweed, so I just go ahead and try that in the VM and
downloaded some random mp4 file. And here's what I found.
The error reported in dolphin is "Could not find video stream", so indeed there
some error happens. After further investigation, I installed ffmpeg command
line to and try to decode mp4 file manually and ffmpeg gives me error for not
having h264 decoder. So I think your problem is the ffmpeg build doesn't have
relevant codec support.
I browsed opensuse repo on pkgs.org and older version of opensuse (15.2) does
have libx264 but it's removed in tumbleweed.
I also tried ffmpeg in Packman repository which is built with libx264 support.
After installing that, dolphin thumbnail just starts to work in opensuse
tumbleweed.
So I think it's just a packaging issue.
I think libx264 is removed from opensuse due to patent, FYI:
