I am able to crash Shotcut 20.04.12 consistently when adding multiple mp4s from the playlist to the timeline using the Playlist “Add selected to timeline” option.
Though perhaps a coincidence, the crash occurs when the source window is active and its content is paused within the clip. When the cursor is at the 0:00 position or (on reload after the crash) the source window inactive, the timeline loads from the playlist without a problem.
I am running Windows 10.0 Build 18363 on a Dell Inspiron 15-3567
I have not been able to reproduce this. I tried with an existing timeline as well as removing all tracks to let it create V1 as well as adding V2 and sending to there. I tried about 10 times with up to 16 playlist items selected (all videos except 1 audio).
I struggle to understand how that could make a different per the code. I tested with both a playlist item in Source as well as something not in Playlist or Timeline. I also tested while Source is playing.
But thanks for trying to help by reporting your problem. Maybe some more information will come to light - some other condition required to reproduce the bug.
Yes, it did not make any sense to me either, but it was the only consistency I noticed.
I no longer can reproduce it either. But it happened four times in a row before I opted to post it as a possible bug. And has happened infrequently before.
Perhaps it is a conflict with some other open application.
I’ll try to remember to run my screen recorder the next time I load multiple clips to the timeline.
Very curious.
If I start a project, and add any media to the timeline, Video, Image or Audio. It just closes. Even creating a blank track and it closes. I have tried with OpenGL on and off. Same.
It was working fine on Ubuntu Budgie 18.04, but I have now reloaded to Ubuntu 20.04, and it doesn’t work.
I am running the version of SC from the repository, and trying to work with projects that are 1920x1080x30.
I have a Dell Vostro 1015 with 4GB RAM and a 32GB SDD Swap. Everything I do works flawlessly, but not working with SC since reload.
Gone through the forums and tried all the advice I could find, but nothing made a difference.
Hi. I’ve a similar more drastic problem after launching Shotcut version 20.02.21 on Ubuntu 20.04 LTS I find if I try to add a video track to the timeline it crashes Shotcut. I have no project files loaded.
Then running it under GDB I can see a crash stack trace. But forum won’t let me post it. Ah I had to remove greater/less than signs
I’m happy to debug any test code if others cannot reproduce this bug.
Then running it under GDB I see the following crash stack trace:
