--- Comment #23 from Weng Xuetian <wen...@gmail.com> --- Since can be made to work on some system with given version, it is less likely to be a bug in the package but more likely to be either your system has some misconfiguration or packaging issue. Here's the things I suggest to be checked : 1. Check if dolphin has the video thumbnailer enabled 2. I'm not sure what's your repo setup, leap 15.2 doesn't have 20.12 so are you using mixed packages or additional 3rd party repo? you may want to check carefully if everything matches expectation, and also list all the relevant packages version installed on your system, including libx264, all relevant libav* packages and ffmpegthumbs. 3. While I think it's unlikely to get broken linkage on rpm based system, what is your output of ldd /usr/lib64/qt5/plugins/ffmpegthumbs.so does it show anything "not found"? When you run dolphin from the command line, does it give any error that seems related to "video" or "stream"? -- You are receiving this mail because: You are watching all bug changes.
