Unable to load video clips on shotcut

Bug
1

  • My OS is ubuntu 24.04.4 LTS

I installed shotcut via snap –classic.

  • I’m using Shotcut version 26.2.26

  • I will open a new project and click on “add files to playlist” and attempt to add an mp4 file, but it will not upload. This used to work for me on the previous version

  • I will also click “open file” and click on the file and it will not open

  • I also get an error stating “Failed to open ”

Please see the log:

It is not clear what the problem is except perhaps that mp4 file is bad. Did you try another one from a different source? I can confirm that the 26.2 version of the snap on Ubuntu 24.04 is working for me.

This tells me that it is failing to load the FFmpeg plugin for MLT. Maybe there is a library conflict somewhere on the system., or there is a new common library linked with FFmpeg that cannot be bundled and that is not on your system.

This last set of lines are the libraries that are not bundled and must come from the system. You can follow my steps to look for something missing (ti will say “=> not found”)

Other clips did, in fact work. I was also able to load the clips onto VLC media player and confirmed that the clips weren’t corrupted. One thing that I did try to do, before I had this failure, was try to load a video file from an external hard drive. After that, not even the local files on my laptop would work
