Run MC from the Terminal and post the error here. If you're using Ubuntu 14.04 LTS, Linux Mint or Elementary OS you may need to use the fix above.

[bob]

Hi Bob,

I have upgraded to 21.0.39 and it is crashing for me. How can I help troubleshoot, what do you need?.

Kind regards,

Nick

Please state what distro you are running on if it's not Debian Jessie.

There are issues with older versions of ubuntu (non-Debian distros are user supported).

Thanks Awesome Donkey great idea, I will do that good call.

I am running vanilla Debian so don't think I need the fix.

Hi Bob,

Thanks for the response.

No it is Debian Jessie not something else.

In better news I have gone back to 0.39 and it has been stable for two days now not a blip. I am not sure if it is the reinstall or bringing the system up to date though it was not far behind, a few weeks maximum.

I will update if I find anything.

Cheers, Nick

The 0 devices message is from JRWorker. It will always find 0 devices for the time being since CD support isn't in MC for linux yet.
The segfault could be from JRWorker or something else. (like a parse of a bad media file).
You could turn on logging and look at the end of the log.

You could also turn off Media Network for testing purposes and see if the segfault still happens.

Hi bob,

Will do. Might be a dumb question but how do I turn on logging? Is there a command line switch or a config file or a setting?

Turning off Media Network will be a challenge I am using Media Centre on linux primarily as a server. Will see how I go.

Logging is under the Help menu.
It leaves a log file in the ~/.jriver/Media Center 21 directory.

[bob]

This one isn't up in the repository yet as I'd like to get some feedback first. Read the changelog for the base 21.0.48 in this forum.

[Awesome Donkey]

MC's way quicker to exit now, which I like.

[bob]

MC's way quicker to exit now, which I like.

I noticed that too.
Can you try 21.0.48-3 and see how that works?

[Awesome Donkey]

Yep, still pretty quick to exit. That pretty much deals with one of the two performance issues I've noticed for a long time now. The other being there's a significant lag/lockup between the transition of Importing Media (when manually running Auto-Import) to displaying the Import Summary. Of course, this 'issue' doesn't exist on Windows or Mac.

There's another thing I've noticed for awhile now... when opening MC I notice the mouse cursor (on Ubuntu as the example here) appears as busy/spinning and not the normal mouse cursor for about the first 30 seconds. I thought it might be media network, but I disabled it completely (and all other features, actually).

Launch feedback specified in the .desktop or elsewhere?

[Awesome Donkey]

Good idea, I fixed it now.

StartupNotify= needs to be set to false instead of true.

[Awesome Donkey]

While I'm on the subject, I've been looking into further why MC randomly will still open additional launchers in the dash even though using StartupWMClass *should* fix it properly. Even with the fixes lately I'm still noticing the issue and I'm trying to get to the bottom of it.

Some links:

http://askubuntu.com/questions/36434/how-can-i-remove-duplicate-icons-for-launched-java-programs-in-the-launcher
http://askubuntu.com/questions/248826/set-multiple-values-for-startupwmclass-to-group-under-same-launcher-in-unity
http://askubuntu.com/questions/367396/what-represent-the-startupwmclass-field-of-a-desktop-file

So, when I run xprop|grep WM_CLASS on MC I get the following;

Code: [Select]

WM_CLASS(STRING) = "JRiver Media Center 21", "Media Center 21"
I've tried setting StartupWMClass to JRiver Media Center 21 from Media Center 21 to see if it makes any difference, and it doesn't seem to. It'll still randomly launch with an additional launcher in the dash. I then ran xprop|grep WM_CLASS on other apps including Chrome, Firefox, Synaptic, Image Viewer, GIMP, gedit, etc. I'm beginning to wonder if it's because of the spaces/name itself of the MC class causing this. Looking at other apps none of them have spaces in the names - in fact they use dashes instead of spaces.

Maybe it'd work if MC's class was changed to something like this (based off what other apps are doing);

Code: [Select]

WM_CLASS(STRING) = "mediacenter21", "Media-center-21"
Thoughts? I wish this could be tested to see if it fixes the multiple launchers issue once and for all.

It was added to the desktop file because of this thread.

I've noticed that it's not unusual for the spinner to stay around for a while when apps are started.

I don't want to arbitrarily change the MC window class and name.
There isn't anything in the link or in my X manuals that indicate that the Class name and app name must not have spaces in them.
Seems to be a desktop bug to me.

[Awesome Donkey]

It's odd, I've ran xprop|grep WM_CLASS on every app in Debian and Ubuntu and every single one doesn't use spaces - just dashes or dots.

Seems to be a desktop bug to me.

I thought so too, but Unity works fine with every other launcher. Maybe Unity is able to trigger this issue, whereas other DE's don't?

I'll keep digging around.

[bob]

I'm hoping we are about done with the threading changes. Would appreciate some testing before it gets into the repository.

[Awesome Donkey]

Working fine here thus far.

[bob]

For possible move to the stable repository, currently up in the latest repo.

[Awesome Donkey]

Is the stable repo working yet? I still get a 404 on it: http://dist.jriver.com/stable/mediacenter/mediacenter21.list

[mwillems]

I'm seeing strange behavior with the progress bar on Arch with Gnome (using the amd64 build of jriver).  Once I seek the progress bar gets "stuck" and flashes on the screen indefinitely until I change the volume or do something else that forces the lower OSD to redraw. 

Another user is seeing it as well: https://yabb.jriver.com/interact/index.php?topic=103590.0

Bob:
On another TW machine, this time I uninstalled i386 and installed amd64 and now I get the "trial period has expired" (which happens everytime I try amd64 after having i386 installed).

Anyway, after the "expired" msg, it segfaults with this:

I've seen a lot of segfaults recently -> http://yabb.jriver.com/interact/index.php?topic=103140.0

some of them have been "fixed" by deleting ~/.jriver , i.e. effectively a fresh installation, but not all

[audiotone]

Since a few day MC21 crashes (shutdown) when I try to connect to my audio files via library management...

so I have to play each file individually to prevent MC21 to shutdown. not very practical!

used to work perfect...

I did a clean install (again) of Ubuntu Studio 14.04.4 64 bit...and JRiver via terminal procedure.

same problem...shutdown as soon as I want to make a new library for my audio files...

My guess is that it has something to do with chrome stopped supporting 32 bit...happened around the same time as I got errors about 32 bit chrome...

now everything is 64 bit (I hope)...but problems with jriver are still there...

what can I do to fix this?

[Awesome Donkey]

Is the cover art (Get From Internet) feature to blame for the crashes in 21.0.61 like it is on the Windows and Mac side?

[bob]

Most likely. Should have a new one up in a few minutes.

[Awesome Donkey]

Thought so, that's why it didn't affect me as I don't use that feature (I manually handle all cover art).

[bob]

And I didn't see it on testing since I wasn't missing any coverart on my test machine.

[bob]

Fixed the cover art crashing bug and reverted a change for DLNA renderer volume getting that caused sluggish GUI performance when used with a slow renderer.

So far testing the multiple MC Unity launcher issue has been positive. I've opened and closed MC over 20 times now without issue. I'll still be testing this another 20+ times but so far it's looking good.

EDIT: Just happened once twice three times thus far! >_<

Sorry, what "happened"? Multiple MC's or multiple icons or something else?

[Awesome Donkey]

Multiple icons appearing in the Unity launcher when opening MC. It's definitely a lot better now with it only happening 3 out of 40 times.

[bob]

I don't see anything wrong with the way MC is setup now regarding that.
My guess is that there is something weird about the timing of the startup notification and the amount of time it takes MC to start.
I notice the spinny wheel for what seems to be an inordinate amount of time.

[Awesome Donkey]

Yeah, it's an odd one but it seems to happen rarely now, which is fine with me as I can just close MC and reopen it. Nonetheless I've switched from Unity to GNOME + Dash to Dock and it's much, much better than Unity.

I notice the spinny wheel for what seems to be an inordinate amount of time.

Ah, that. Yeah, I believe that's caused by using StartupNotify. As far as I know, StartupNotify is needed for the launcher stuff to work correctly. Hmmm.

21.0.63 has been running well for me, mostly.  The only thing I'm regularly experiencing is a crash on Server copy when I close a client copy connecting to the Server library.  I see this in the syslog on the Server:

Code: [Select]

mediacenter21[5588]: segfault at 33d9000 ip 00007f0ef6a03ab0 sp 00007ffe56b1d2e0 error 4 in libX11.so.6.3.0[7f0ef69c5000+130000]
Both Server and client are running MC 21.0.63.  The server is Ubuntu Server 14.04 LTS, the client is Linux Mint 17.3.

Can you post the whole error message? It should also show up in the output from dmesg

Perhaps a corrupted settings file.
remove the

directory and restart MC.
You will lose your settings and license but not the library. You can just re-enter your license code.

Great thanks, Bob.
It's work.
but why it occurs already the second time?

[bob]

Great thanks, Bob.

I don't know why that would happen unless perhaps the machine crashed while MC was running?

[bob]

The 21.0.70 build has a change to the copy/paste method. Some testing would be good. We are looking to see if we broke other control key functions (we found a few that didn't work before already). Also to make sure it doesn't crash MC under an unusual situation.

[Awesome Donkey]

So far it's working pretty good here.

[Awesome Donkey]

Okay, more testing in my Linux VMs - copy and paste doesn't seem to work into Customize Display. Anyone else confirm? The clipboard is correctly copied from the host to guest VM, so that isn't an issue. However if I attempt to copy anything within MC (e.g song title, artist name, etc.) and paste that into gedit (all within the VM), it doesn't work.

I'll test from the native Arch install here in a few mins.

EDIT: Anything I'm writing into gedit/Text Editor then highlighting and copying via the right click menu works (and thus the contents are in the clipboard) however trying to paste said contents in MC via Paste from right click or CTRL+V doesn't work. Paste isn't selectable so it's not reading the clipboard.

EDIT 2: Okay, tested from the native Arch install and the results are the same. Copying from outside MC (e.g gedit) and pasting to MC doesn't work. Nor does copying from MC and pasting to gedit. However copying and pasting within MC itself seems to be working fine. So that's pretty much it here - I've confirmed this behaviour in the native Arch install, Ubuntu VM, Arch VM and Mint VM. I'll test the Debian VM here in a few mins, but I suspect the result will be the same.

EDIT 3: Same result with the Debian VM.

Good day.

Definition of testing system ... a) I have no .Xdefaults nor .Xresources files on my system. b) I am using twm for window manager  .  c) I had to ask where the Customized Display menu was (right-click on "JRiver Media Center 21" text) located.

With gedit, I can type there and select (double/triple click for example) and then control-C (or right button->copy). Go to MediaCenter and control-V to paste (or right button->paste). 

The opposite shows how broken various X applications are with regards to CLIPBOARD/PRIMARY cut and paste.  If you control-V into gedit, it pastes. The right button->Paste is greyed out in gedit. But, control-V works fine.

I do not have the middle button paste of selections from PRIMARY working.  If you select in Media Center, it stays in MediaCenter. It does not do a selection clear event to whoever the owner of the PRIMARY selection property is, nor does it change the PRIMARY property to contain the selection. (On the list ...along with virtual keys and control keys for menu options...)

[Marshall]

I am guessing that the "Paste" menu un-grayed-out in gedit depends on the selection clear event for PRIMARY property arriving. "Most interesting..."   ?
