libmpv1 deprecated on Ubuntu 24.02 LTS/Linux Mint 22

[FlameSoulis]

Attempting to setup the build environment for this project requires libmpv1, which is no longer available as of Ubuntu 24.02 and, by extension, Linux Mint 22. Compiling with libmpv2 does work with a few warnings, but I have been unsuccessful in running the project, resulting in errors related to #228.

I have both symlinked and directly copied the assets folder in case the auto-detection did not work. This is being tested using x11/Cinnamon.

you can do a temporary fix by symlinking libmpv.so.1 to libmpv.so.2, ln -s /lib/x86_64-linux-gnu/libmpv.so.2 /lib/x86_64-linux-gnu/libmpv.so.1, at least for when you build it from source. Don't know what will happen for built binaries.
Still get the [1109/212414.801860:WARNING:resource_util.cc(94)] Please customize CefSettings.root_cache_path for your application. Use of the default value may lead to unintended process singleton behavior. which is worrisome and would like to know why.

The crash seems to be unrelated to the change to libmpv actually. Looks like CEF doesn't like some parameters, I'll need to investigate this a bit further. The warning about root_cache_path is something we should be able to remove too.

[FlameSoulis]

Anything I can do to provide more information or test? I'm a bit rusty when it comes to debugging, let alone in Linux.

Hello, I got the same issue after building and testing the app, doing --no-sandbox or running as root return something just like this :

wiblum@WiBlumMiX:/media/795FF77D55816222/SteamLibrary/steamapps/common/wallpaper_engine$ sudo ./linux-wallpaperengine 2344239224 --no-sandbox

And then crash (same without sudo)

Running it normally :

Trace/breakpoint trap (core dumped)

And it also seems like the app won't respond for any others arguments that have an impact on something from the workshop or the steam app (--list-properties)
Also what is that CefSettings.root_cache_path ? I can't really find it anyway on the github repo. I don't check all subfolder or else but I just wonder where to correctly set it.

Also this bug always get an issue with zygote, it may be related to a zygote version that isn't very compatible with the script, I'll check that later.

[WiBlum]

Can I ask you a simple question, did you use something like electron 34, because I remember seeing zygote or zenity thing in another app that I got trouble to run.
I'm talking about cider which had a similar issue with zenity, same error and they told this is probably an hardware acceleration issue, which is 1 of the issue I had with steam and other chromium browser (like electron)

Issue from cider2 : ciderapp/Cider-2#929
Direct post : ciderapp/Cider-2#929 (comment)

I don't think it's a electron issue since I don't remember seeing wallpaper engine using some kind of electron but it's probably good to see if someone else as already explained what can make a zygote 215 error.
anyway I'll search a bit more

[WiBlum]

EDIT OF EDIT :
Sorry if I spend to much message, I got a way to make it run even if it doesn't due to zenity, it turn out that it's related to an hardware acceleration issue or something from zenity and the gpu, chrome and cider had this issue when the Nvidia driver or else are, hmm not working as excepted, here is how I can manage to make it run, on the cpu ;-;

I simply used --no-sandbox flag and tell the full path of the wallpaper I installed from the workshop.
I used 1845706469 as a test :

./linux-wallpaperengine /media/795FF77D55816222/SteamLibrary/steamapps/workshop/content/431960/1845706469 --no-sandbox

here is full log when it worked :

As you can see it struggle to process with my GPU, it's a Nvidia RTX 3080 and here is other useful information if needed
OS: Debian GNU/Linux bookworm/sid x86_64
Kernel: 6.1.0-21-amd64
Uptime: 5 hours, 18 mins
Packages: 5060 (dpkg), 50 (flatpak), 11 (snap)

GPU: NVIDIA GeForce RTX 3080

And other apps like torch in python can see the gpu and use it :

wiblum@WiBlumMiX:/media/795FF77D55816222/SteamLibrary/steamapps/common/wallpaper_engine$ python3 -c "import torch; print(torch.cuda.is_available())"
True

I haven't try it yet with my liquorix kernel but since it's a kernel that only does optimization (in gaming as example) I'll pass.

Using --no-sandox and full path, I wasn't able to pass the 1 fps wall with my current CPU I go check why does it won't work on the gpu.
