Crash importing MP4 file (Ubuntu 22.04, using 3.2.1-dev)

[asgrim]

Describe the bug:
If I try to import some MP4 files (consistently the ones recorded from my Insta360 Go 2, if that helps), e.g. by drag/drop into OpenShot Project Files or I use context menu "Import Files" and select the file, I get a segfault.

I have had this issue for some time, but thought I'd try with the latest daily. Same issue exists in 3.2.1 stable. I have also tried updating ffmpeg, since the ffmpeg with Ubuntu 22.04 is version 4.4.2-0ubuntu0.22.04.1+esm5 which I think is quite old. I used an ffmpeg7 PPA to upgrade to 7.0.2-1build1~jammy but the issue still persists.

Steps to reproduce the behavior:

1. Launch OpenShot (using 3.2.1-dev daily from PPA), from terminal openshot-qt
2. Drag the sample file into OpenShot
3. OpenShot disappears, segfault is displayed in terminal

Expected behavior:
The file should be imported.

System Details:

• OpenShot Version [e.g. 2.4.3]: 3.2.1-dev
• Operating System / Distro: Ubuntu 22.04.4

Log Files:

• openshot-qt.log

Exception / Stacktrace:

Output shown when running from CLI:

• openshot-output.txt

Hello @asgrim
What happens if you run your source .mp4 file through a converter like VLC, HandBrake, or ShutterEncoder and convert it to .mp4 again with a different name. Now import this newly created .mp4 file into OpenShot.

Indeed, as a workaround in the past I have used ffmpeg (I think something like ffmpeg -i input.mp4 output.mp4, can't remember off my head) and that sidesteps the problem, but sometimes I have a huge number of videos, sometimes many GBs to do, and this can be very time consuming.

[Colorjet3]

Well, VLC, HandBrake, and ShutterEncoder have a batch process option to speed up the conversion process. I often use ShutterEncoder and it works really well.

Hello @asgrim Is it possible that you can share your entire project so that the lead developer can play/test with it in his environment so he can debug this issue? If yes, please copy all your source files (videos, audio, and image files) in the same directory as the .osp file and then zip them up and share here.

Thank you in advance.

It is reproducible in literally an empty project. A video that causes the issue is attached in my first comment above.

When I click on the link it just plays a black video for 3 seconds.

Yes that is correct...the content of the video doesn't make much difference. Any video from that device causes OpenShot to crash when I try to import it :(

[influential-eliot]

I have the same issue.

• Version: 2.6.1
• OS: Debian 12 (wayland gnome 43.9)
• Source: Deb Package
• GPU Drivers: Nvidia proprietary

I just want to quickly edit a screencast, so will try shotcut instead, but hope this gets sorted. :)

[Colorjet3]

Lots of bug fixes and enahancements in the latest dev daily build.

1. Go to openshot.org/download/#daily and get the latest AppImage.
2. Make it executable and run it.

[asgrim]

Thanks for the ping; I don't use AppImage, but I tried the latest DEB (3.2.1+dfsg2+1704+202410122047~ubuntu22.04.1), but the issue remains. Steps to reproduce:

1. Download the above example MP4 file
2. Run OpenShot
3. Click & drag the MP4 into OpenShot project files list

What is expected: file should be imported to the project files list

What actually happens: OpenShot exits with segfault.

Hello @asgrim

Please try the AppImage just to see if it resolves your issue? You can get rid of it then when you are done testing. This will help the lead developer to troubleshoot as well.

[asgrim]

@Colorjet3 the issue does not persist in the AppImage. I suppose that points to a dependency issue somewhere :)
