Created attachment 124623 [details] Render Popup message SUMMARY Will not render, getting message: This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. Available platform plugins are: direct2d, minimal, offscreen, windows. STEPS TO REPRODUCE 1. Attempted in new project - same result 2. Old project - same result 3. OBSERVED RESULT: Message popup stating the above, NO MP4 file EXPECTED RESULT: I expected a rendered MP4 file, failed before creating one. SOFTWARE/OS VERSIONS Windows: 10 10.0.18362 Build 18362 macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION: Works fine in release 19.08.2 for both project but not on new release 19.12.0. Tried the following: Deleting %AppData% kdenlive folder nothing. Making sure qt.conf file exists. Installed both standalone and full versions. Folder permissions are to all. and above mentioned files are in bin\platforms folder.
Created attachment 124624 [details] qt.conf Please put attached file "qt.conf" into the "bin" folder (the folder where Kdenlive.exe is).
That file already existed with the same values inside but I used yours and there is no difference still not rendering.
Hit CTRL+SHIFT+, (comma) -> environment –> make sure the paths point to the same path as "MLT profiles folder".
That worked! Many Thanks! Jim
Thank you for the feedback. Glad to hear it works. I updated the Kdenlive manual with this solution.
When I install kdenlive 19.12.1 for all users (C:\Program Files\kdenlive) and launch kdenlive, it fails to start, instead producing the following error: > This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. > > Available platform plugins are: direct2d, minimal, offscreen, windows. Not just rendering fails, but starting the program at all doesn't work. Adding qt.conf (https://bugs.kde.org/attachment.cgi?id=124624) to \bin\ fixes the issue. Where is this issue and workaround documented in the manual? I tried searching for qt.conf in the KDE wiki (https://userbase.kde.org/index.php?search=qt.conf&title=Special%3ASearch) with no results. I don't see qt.conf mentioned in https://userbase.kde.org/Kdenlive/Manual either.
Thank you for the feedback. I added the solution with qt.config here: https://userbase.kde.org/Kdenlive/Manual/Windows_Issues
