Snakeoil Forums

I have been using Snakeoil 1.1 with JRiver 25 as music server since 2019 with great result, it plays great and no problems whatsoever.  
Now when version 1.2 has been released I decided to try it out, in Vmware, it's much easier to install with the new script on top on Ubuntu server.
However I can't get Jriver 27 to start, I also have some dependency problems during install but I sort them out:
Install:
 
I then run "apt --fix-broken install"
 
Jriver 27 is now visible in the Music Servers section in the WEB GUI, I tick the box and press "Save and restart players".
I now login to the VNC server, with Remmina, VNC start up but there is no JRiver only the wall paper.
I have restarted Snakeoil but no luck.

The log have this line about Jriver:
After install
 

After reboot
 

I also updated to Snakeoil 1.2.1 just now and the same problem.

Please advice, does anybody has any suggestion on how to solve this?
agent_kit, is this something you can solve to the next build?

I'm using a remote KVM to work around this. Been meaning to write a blog about this, but still waiting for other misc parts to arrive before I can do it. PiKVM allows me to load a ISO remotely and boot up a remote computer. It's really flexibile.

I suspect running a VM could be the issue for the fault. Make sure:
1. You are giving your virtual machine enough virtual memory
2. JRiver might be using some CPU extensions that is not enabled in your VM By default. Shut down your VM, go to settings, under Processor, enable all options (or one by one) and see if it works. Alternatively check what extensions JRiver needs and see if you can pass it through somehow. Proxmox gives me more flexibility to do this, unsure if VMWare Workstations do the same.

Thanks for the prompt replay.
I have the following settings in Vmware Workstation 

• Memory = 4 GB
  
• Processors = 2
  •  Options:
    •  Virtualize Intel VT-x/EPT or AMD-V/RVI
      
    •  Virtualize CPU performance counters
      
    •  Virtualize IOMMU (IO memory management unit)
      

I tried to disable/enable these, still the same error:

However, I install Ubuntu 20.04 Mini (Desktop install where you select "mini" during the installation), with the exact same VMWare settings, and there Jriver starts up.

I also notice one thing, have you changed the windows manager to IceVM since Snakeiol 1.1, wasn't another windows manager used then?
If yes, can that be the problem?

II did an search on Jriver and segfault and found this: https://yabb.jriver.com/interact/index.p...#msg707248
It's quite old, but they talk about a display driver, has that been updated in Snakeoil 1.2?

I will try to test some more during the week.

That means it's not a CPU extension that is causing the issue. Look under graphics and see if you can either:
1. Pass through your graphics card into this VM (make sure IOMMU is enabled)
2. Enable 3D graphics

See if JRiver will behave properly now in a VM. If all else fails you probably have to run this without virtualisation.

In theory JRiver can do some checks to make sure it has all it's hardware it needs and not seg fault like this. Look for any JRiver log file and see if actually says what the problem is.

Snakeoil always have been using IceVM. It's kind of a bad windows manager, but it's quick to load up and have minimal memory resources, and have a GUI that is more or less usable.

In VMware the following is already set:

• IOMMU
  
• Accelerated 3D graphics
  

I cant find any Jriver log file, i have search for any file named jriver but no hit.

It is working in VMWare in Ubuntu 20.04 mini, that has the exact same vmware settings, the only difference should be that there is a desktop environment installed right and some package in that desktop environment is what Jriver needs to start, right?
But the next step will to see if it works in real PC.

Could be. But we are just guessing, it's very hard to tell because that segfault doesn't really give us much to go on. JRiver log file (if it exists) should tell us exactly what's happening.

I have done some digging and found this:
In Ubuntu Mini I found the following log files in jriver directories:
- /home/vmware/.jriver/Media Center 27/Web/Log.txt
- /home/vmware/.jriver/Media Center 27/Web/Cache/LOG
- /home/vmware/.jriver/Media Center 27/Web/Cache/LOG.old

According to this info https://wiki.jriver.com/index.php/Logging you have to turn on logging.
after turning on logging is there a new log file here:
- /home/vmware/.jriver/Media Center 27/Log.txt
But in Snakeoil is there no Log files at all, not even the Web folder, so it looks like Jriver crash during startup before it can create folders an log files.

The next step will be to install Snakeoil on a real PC and see if it's works.

It's running as root. so try look in:

Sorry, no hit.
In the ~/.jriver/Media Center 27 folder is the following folders 
I can't find any Log.txt or similar file in any of those folders, all files except Temp was created when I install Jriver, and the Temp folder is empty.

So, I will try to install Snakeoil on a real PC and see if it's works.

I have now install Ubuntu server 20.04 and Snakeoil 1.2.1 + Jriver 27 on an old NUC5 if have, but it's still the same problem; mediacenter27 segfault 10 error 4. 
I have also tried to install both Jriver 25 (that I has running on Snakeoil 1.1) and Jriver 28 but none of them is showing up in the Snakeoil media servers list, so I cant start them.
Is there any way to manually enable Jriver 25 so it starts automatically or manually (just to try to narrow down the problem)?   
or is it possible to add the possibility to enable Jriver 25 and Jriver 28 in the next Snakeoil release?
