The same issue does not happen on BambuStudio, which I'm currently using for both A1 Mini and K1 Max.

[oltas123]

Same issue but with both OrcaSlicer and Bambu studio on Debian 12. Tryed it only in Lan Mode

Same issue but with both OrcaSlicer and Bambu studio on Debian 12. Tryed it only in Lan Mode. But works with Manjaro from USB on the same Computer.

[rmeissn]

Still an issue with v2.1.1

[IetIesAai]

Still an issue with v2.1.1

and 2.2.0, Fedora, cloud mode

[3dRikal]

Same Arch/Catchy-OS

[danexpo]

Same issue with A1 Mini, P1S on Fedora 41.

Issue is fixed in Bambu Slicer's latest release 1.10.0 Public Beta2

[mf81234]

Can confirm same issue on Windows 11 with X1C, fixed in Bambu 1.10.0 Public Beta2

[3dRikal]

No issues in current release of Bambu Studio

I managed to reproduce the same behavior on BambuStudio 1.9.7.52 - it crashes when launching the webcam. It looks like the issue is related to a version/release of the encoding/decoding of video, since BambuStudio packages a version of the libraries that usually ship with ffmpeg. Also, the network plugin is redownloaded if you first open and run 1.9.7.52 then run the latest 1.10.1 - I'm feeling that Orca may be running an outdated/incompatible version of the plugin and/or it is trying to use the system ffmpeg libs.

Still an issue with Orcaslicer 2.3.0-beta on Fedora 41

[bseidenberg]

I can replicate on 2.2.0 on Debian.

Running it under GDB, this is what the fault and stacktrace look like:

Thread 192 "source:src" received signal SIGSEGV, Segmentation fault.

Are you able to test with 2.3.0? For me (Windows 11) somewhere between beta2 and rc fixed this issue

[bseidenberg]

Yes, still crashes on 2.3.0:

This is the AppImage (not the Ubuntu-22.04 version) from the GH releases page.

[bendwv]

Still getting this issue on Fedora 42 kernel 6.14.5-300.fc42.x86_64 (64-bit) with KDE Plasma. Using the appimage.

Still an issue with Orcaslicer 2.3.0 (Appimage) on Fedora 42, Gnome

[AlexanderSalge]

Seems to also be an issue on 2.3.1 and P1S

[nyghtly-derek]

Encountering this problem using OrcaSlicer 2.3.1 on Bazzite (bazzite-dx-nvidia:stable) with my Bambu Lab P1S.

Video works fine in Bambu Studio.

Before I began seeing segfaults, I had a separate issue with missing H264 codecs. Fixed that by installing some gstreamer plugins.
