Latest AppImage Crashes Trying To Display P1P Video

[nmcbride]

Describe the bug
When I try to display the video from the P1P using the latest AppImage (Bambu_Studio_linux_fedora_v01.06.02.04-20230427094209.AppImage) one of two things happens:

1. It asks me for the IP and Access Code -> I enter that info -> It says it connects and then crashes.
2. It just crashes.

Expected behavior
Should stream the video as it does in earlier versions.

I have two previous versions downloaded as well:

• Bambu_Studio_linux_fedora_v01.05.00.61_20230314200047.AppImage
• Bambu_Studio_linux_fedora_v01.06.00.65_20230417141721.AppImage

These both stream the video perfectly fine. Albeit low quality and low frames on the P1P.

it is the same as #1665 (comment)

so what is your OS version?

and could you also check the libjpeg version on your system?

@lanewei120

According to the issue you linked the AppImage I am using is the one that has already had the libjpeg version downgraded in it.

I'm on Manjaro.

This is what is on my system:
libjpeg.so
libjpeg.so.62
libjpeg.so.62.2.0
libjpeg.so.8
libjpeg.so.8.2.2
libjpegxr.so
libjpegxr.so.0
libjpegxr.so.0.0.0

[lanewei120]

then we need to check the libjpeg used by gstreamer
for example:
readelf -d /lib64/gstreamer-1.0/libgstjepg.so

on my Fedora 36, it uses libjpeg.so.62

Looks like mine is .8

[lanewei120]

the root cause is the libjpeg version built with the appimage is jpeg6
and on your system gstreamer uses jpeg8

We just found on Fedora, some uses jpeg6 and some uses jpeg8
and maybe we have following fix methods:

1. built gstreamer related plugins as static libraries into BambuStudio which use the same jpeg version
   or
2. release two images for fedora

1 is difficult to achieve, we will think more about it

[WayneManion]

Isn't the whole point of AppImage that it has all the dependencies built-in? The idea is that you only have to release one AppImage that works in all distributions that support AppImage.

I am running Arch fwiw.

I am running Arch. I am running the AUR package (built from source) from here: https://aur.archlinux.org/packages/bambustudio-git

The application doesn't crash when I click the play button to view the camera stream, but I can't see any video either. It just says:

Loading Failed [2]!

The gdb logs from running the built-from-source version of the app is here: https://pastebin.com/bhUK8JAh

I am not familiar with this,
I think it is caused by gstreamer not included in the appimage, gstreamer uses libjpeg which has a different version

[nmcbride]

It is frustrating that the appimage isn't self contained.

I recently just switched over to NixOS and tried to run the appimage and couldn't. Then I thought I'd use distrobox and run it but it needed a ton of dependencies to be installed.

Ended up installing from source on NixOS and also have the black screen to the P1P with with the Loading Failed error.

Could we get a flatpak build that is self contained that we could just install from flathub like prusaslicer?

Would it be really complicated to include it?

btw: version 1.8.0 still crashes when trying to start the video stream for a P1S.

Update: BambuStudio_linux_fedora_v01.08.02.56-20231213.AppImage works on Debian 12!

Update: BambuStudio_linux_fedora_v01.08.02.56-20231213.AppImage works on Debian 12!

Cnfirmed for me Debian 12 video crash using ubuntu, using fedora version require to install libosmesa6 but then it works and video doesn't crash. Using the ubuntu even after installing libosmesa6 doesn't help though.
