Start it from the terminal with the /BuiltInBrowser switch.

mediacenter34 /BuiltInBrowser

I receive the same segmentation fault error when using the /BuiltInBrowser option on Ubuntu Studio 24.10

What GPU is being used? You'll probably have to wait for Bob to respond.

Segfaults are sometimes hard to track down and may require you to run MC through gdb in the terminal to get more info about where it's failing exactly. How to run MC34 through gdb you do the following in a Terminal...

Code: [Select]

gdb mediacenter34
If it asks whether or not to enable debuginfod for the session put in y and hit Enter, then you'll see it say (gdb). When you see this type in run and press Enter and it should start to run MC34 and then it should segfault again but this time it should display more information about the segfault. Copy and paste and post that info here.

My GPU is a NVIDIA GeForce GTX 1660 SUPER/PCIe/SSE2

Here is the output of the gdb command:

Bob said the segfaults could because of corrupt settings files. Try what he suggested here: https://yabb.jriver.com/interact/index.php/topic,141310.msg980605.html#msg980605

Removed both of the settings files, ran gdb mediacenter34 with the built in browser option and got this:

Tried it again, and in addition to the previous output, it included these lines after the segmentation fault:
(gdb) [0520/152951.107775:WARNING:angle_platform_impl.cc(49)] RendererVk.cpp:1962 (initialize): ANGLE VMA version: 2003000

And it just kind of hung there at that point, never closing out the command, indicating that it might not be a 'crash' so much as a process gone out of control. Perhaps.

After looking through some other recent forum questions about segmentation faults, I decided to try loading X11 instead of Wayland - and JRiver Media Center loaded up without issue. Just figured I'd let you know my resolution.
