Crashes on video

[olmaverick]

Hi, I've been trying to track down an issue that's been affecting me for a few weeks now, trying to click on a video crashes XnViewMP.

• type of video doens't seem to matter, I've tried mp4, webm and mkv and all are affected
• I've tried purging my cache and it doesn't seem to matter
• autoplay or loop options don't seem to change anything
• both flatpak and appimage versions are affected, at least (as those are the only ones I can easily try)
• versions from current back to at least 1.88 are affected, which makes me think this may be something in xnview that was affected by a system update, as it was at least playing video up to a month ago or so.
• OS: Fedora Kinoite(Silverblue) 42
• Other tools (gwenview, smplayer, vlc, etc.) seem to be unaffected.

When I use the flatpak version, it crashes with no error message; the AppImage crashes with the error:

Code: Select all

/tmp/.mount_XnViewGopDMJ/usr/bin//xnviewmp: line 5: 57943 Segmentation fault      (core dumped) "$usr/XnView/XnView" "$@"

Any suggestions/ideas for other things I can try?

[xnview]

please try to start xnview from a terminal to see logs

I did that, but the only useful output when it crashed was the single line that I put in the post above. Here's what seems to be the point when it loads a video to the point where it crashes:

It says it's dumping core but I'm not sure where it's putting the dump, it doesn't seem to be in /tmp or in my home directory.

i've tried on a clean Fedora 42, and no problem to play mp4 files
Please change debug=2 in your xnview.ini

I have the same issue on Bazzite. The app crashes whenever I select a video file in the file browser (apparently it tries to load a preview)
OS version: Bazzite 42.20250908
App version: XnView MP 1.9.3 (flatpak version)
Logs are attached (with debug=2 in the config)
Here is a core dump: https://mega.nz/file/w4MDDaCB#JADp2ed36 ... dI-PbJvvns

I hope this helps fixing the issue

[olmaverick]

I set debugging on as requested and here is the output. I also have a core dump for this same crash if it would be helpful.

Thanks, the output txt seems to be incomplete?

[olmaverick]

I'll try again.

[xnview]

Try to set

Code: Select all

QT_XCB_GL_INTEGRATION=xcb_egl

[olmaverick]

I set that environment variable and tried the standalone binary version again, but it still crashes. Output attached.

I posted a related thread in July 2024: Crash when opening any DJI drone MP4 file

I think you're not alone with this as I experienced the very same symptoms.
I changed the debug parameter in ~/.config/xnviewmp/xnview.ini as instructed above by others, and fed the output into a logfile, which I just attached here.
At line 324 where it loads the .webm video, it gave me a clue at line 434 where it tried to load X11 display, to no avail, because I'm running on Wayland Plasma, specifically on CachyOS.

Let me summarize my config:

• OS: CachyOS

• DE: Plasma 6.5.4

• Kernel: Linux 6.18.2-3-cachyos

• CPU: MD Ryzen 9 7900X (24) @ 5.74 GHz

• GPU: NVIDIA GeForce RTX 4070 Ti [Discrete]

• ffmpeg: n8.0.1 - built with gcc 15.2.1 (GCC) 20251112

Downloaded .tar.gz version, extracted, ran it, focused on video files in XnView Filebrowser: Crash
Downloaded AUR version, ocused on video files in XnView Filebrowser: Crash

This does not alone happen with .webm, but with any other video file.

The dilemma: Since X11 is being passively-, but surely rolled out in the future to be exchanged by Wayland, what would be the preferred practice to avert this issue?
