Description SR__ 2019-03-25 10:41:19 UTC
SUMMARY
On Windows, I cannot load a clip in a project. Either by copying/pasting in the « Source » area, or clicking the « Add a clip » icon.

STEPS TO REPRODUCE
1. Launch kdenlive
2. drag a file from an explorer window to the « Source » area and drop it.

OBSERVED RESULT
An alert window complains about the incompatibility of the file and tells that it's going to be removed. No clip is therefore loaded.


EXPECTED RESULT
The clip is loaded.

SOFTWARE/OS VERSIONS
Windows: 7 64 bits

ADDITIONAL INFORMATION
-Official beta release downloaded from KDE servers today.

-Tried with ffmpeg packaged with the KDE package and also tried ffmpeg :
ffprobe version N-93451-gc3b517dac2 Copyright (c) 2007-2019 the FFmpeg developers built with gcc 8.2.1 (GCC) 20190212

-I have tried with .MOV, .wmv, .mkv files. An example of a file as parsed by ffrobe is given below.

-If I run ffprobe (from kdenlive directory) on a mkv file, no problem is reported :

This is a problem either with the "kdenliverc" file or you have some missmatch in your "local" folder.
Plesae following the steps here: https://userbase.kde.org/Kdenlive/Manual/Windows_Issues#Any_critical_bug

or under "Qt rendering crash"

You're right, deleting two kdenlive folders and reinstalling, as stated on the page you pointed out, worked for me.
I have previously found this page but failed to understand that it applied to my case.
It is nonetheless surprising to have to install twice the software to have it working, as the problem arose immediately after the very first install on my computer.
Anyway, thanks for the help.

Glad to hear it works. Thank you for the feedback. I updated the manual to be a bit more precise. 

I close this bug. If it still appears in the latest version, please feel free to re-open it and update the affected version number.
