Hi,
I encountered issues with a project I wanted to continue working on after a two-month break. For some reason I cannot open the mlt files of my project because Shotcut crashes. While looking at what is happening in Linux terminal, these errors caught my attention:
[Error ] [producer_xml] failed to load filter “ladspa.1892”,
[Error ] [producer_xml] failed to load filter “ladspa.1882”
[Error ] [producer_xml] failed to load transition “frei0r.cairoblend”
Some lines later I get a message “Segmentation fault (core dumped)”
Using my limited HTML coding experience, I have tried to look at the source code of the mlt file for a couple of hours now, and tried to debug it by commenting some lines regarding these ladspa filters. I also tried to comment out whole chains where I have used these filters without much success. Even if I deleted all chains except one in a separate test file, and try to open it, the mlt file causes Shotcut still to crash. The last line regarding the frei0r.cairoblend appears every time. At this point, I think I have hit a wall when it comes to my skills in solving this issue on my own.
I’m using Shotcut version 24.04.28 on Ubuntu 20.04, and I installed it by downloading a tar file last summer. The file I’m trying to run is here WHT video.mlt (144.6 KB). All my other video projects seem to open okay except this one. I think the only difference between this project and the others I have is that I have used sound filters in some parts of the video here.
If anyone could help, it would be great! I spent about 10 hours editing this content before this issue began
