Comment 1 Jean-Baptiste Mardelle 2024-08-08 11:04:46 UTC

This is most likely a library conflict/mismatch between Kdenlive and MLT. If you compiled by yourself, can you first check that MLT is correctly working ? From a terminal:
melt -query producers
Should output a list of modules, "avformat" should be there

melt path_to_your_video.mp4
Should play the video in a window (press 'q' in the terminal to quit)

ldd /usr/local/lib/mlt-7/libmltqt.so (or whatever path to your installed MLT's libmltqt.so
Check that it is not linked against Qt6

Let me know if any of the following does not produce the expected result
