I can no longer import any videos. I get the same error as posted below.
Most of these videos are videos from my cell phone. But I have tried moving the files to different folders (nope), adding instead of moving files (nope). I tried older mp4 videos from 2008 (nope). I tried an .mov file (nope). I tried turning GPU acceloration off (nope). I tried clearning all the caches (nope). I tried uninstalling all lightroom even preferences, and reinstaling (nope). I am on the most updated 10.4, on Windows 10, recent updates. AMD 3700X CPU. Nvidia 2070 GPU.
The video previews also don't show up in the import screen as well.
I have no plug-ins. Stock install. I've never even heard of mediacore.
I have tried disabling all of these as well. Did not work.
Oh, I also went to the /Adobe folder and tried the renaming the folder to solution.old and it re-populated, that didn't work.
i encountered this issue in osx recently and it was solved by changing a permission in the system prefs. I know you're using Win10, but i wonder if the issue has a similar solution.
Which permission? It may be a similar issue, I'll try things?
I'm having the same problem. Tried importing some videos into LR and got a message saying that "Dynamic Link failed". I am also unable to export videos from the Slideshow module. Has anyone found a solution to this?
