VLC Not Detected

[HeyITGuyFixIt]

I load Quelea 2022.0 (installed from snap on Linux Mint 20 Ulyana, based on Ubuntu 20.04 focal), and I get a message saying to install VLC. It has been installed, so I'm not sure what's wrong. The error log has this:

May 07, 2022 5:52:21 PM org.quelea.windows.multimedia.VLCWindowEmbed lambda$new$2
INFO: Couldn't initialise video, almost definitely because VLC (or correct version of VLC) was not found.
java.lang.RuntimeException: Failed to load the native library.

The error was "Unable to load library 'vlc':
libvlc.so: cannot open shared object file: No such file or directory
libvlc.so: cannot open shared object file: No such file or directory
Native library (linux-x86-64/libvlc.so) not found in resource path (/snap/quelea/950/jar/Quelea.jar)".

The required native libraries are named "libvlc.so" and "libvlccore.so".

In the text below <libvlc-path> represents the name of the directory containing "libvlc.so" and "libvlccore.so"...

There are a number of different ways to specify where to find the native libraries:
 1. Include NativeLibrary.addSearchPath("vlc", "<libvlc-path>"); at the start of your application code.
 2. Include System.setProperty("jna.library.path", "<libvlc-path>"); at the start of your application code.
 3. Specify -Djna.library.path=<libvlc-path> on the command-line when starting your application.
 4. Add <libvlc-path> to the system search path (and reboot).

If this still does not work, then it may be necessary to explicitly add the native library directory to the operating
system configuration - e.g. on Linux this might mean setting the LD_LIBRARY_PATH environment variable, or adding
configuration to the "/etc/ld.so.conf" file or the "/etc/ld.so.conf.d" directory. Of these options, setting
LD_LIBRARY_PATH is the only one that would not require root privileges.

Finally, it is not possible to mix CPU architectures - it is not possible for a 64-bit Java Virtual Machine to load
32-bit native libraries.

More information may be available in the log.

libvlc.so is at /usr/lib/x86_64-linux-gnu/libvlc.so and $PATH is set to:

/usr/lib/x86_64-linux-gnu/:/home/tgocala/.nvm/versions/node/v14.18.0/bin:/usr/lib/x86_64-linux-gnu/:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/opt/gfie-3.6:/opt/gfie-3.6

The folder libvlc.so is found in is listed in /etc/ld.so.conf.d/x86_64-linux-gnu.conf. Not sure what else to do to fix this.

VLC version:

VLC media player 3.0.9.2 Vetinari (revision 3.0.9.2-0-gd4c1aefe4d)

[berry120]

Have you definitely installed the 64 bit version of VLC? The path (x86_64) suggests that might be the 32 bit library.

[frebergguru]

It is the same problem here.

I am running quelea under linux Manjaro Kde. I have the same problem, quelea2022 don't see VLC, I have been VLC user for many years. Is it possible to install quelea2021 via snap, while I am waiting for a solution of the problem with vlc with quelea2022. I need to run videos in quelea.

[berry120]

Is this a regression in 2022 (did it work ok in 2021?)

[berry120]

(Sorry, fat-fingered the button, didn't mean to close)

[helgeheo]

In 2021 there is no question of vlc, and it was possible to run videos. In 2022, I am not able to run videos as long as quelea don't see vlc.

[HeyITGuyFixIt]

@berry120 I purged vlc and all packages with vlc in their names, and reinstalled them explicitly specifying to install the amd64 versions. And it still doesn't detect vlc.

[berry120]

Just a quick note to say I can reproduce this, am working on a fix, but unfortunately haven't managed to narrow down exactly what's going on yet. Only seems to happen with the snap version which makes debugging & releasing a pain. I am actively looking at it whenever I can though.

[berry120]

Update on this one - unfortunately it doesn't seem to be as simple as widening the path, as (at least on my test VM) the VLC library loads ok but causes a hard crash after playing a video for the first time.

For anyone who wants to test to see / confirm if the same behaviour happens to them, that'd be much appreciated just to check it's not something odd with my setup. (You can do so by temporarily installing the "edge" release of the snap - snap install quelea --edge - but it's definitely not stable at the moment so please make sure you don't do that on a system where you rely on Quelea to work!)

[HeyITGuyFixIt]

@berry120 not sure what error you get, but when I try it I get an error from vlc saying:

vdpau_avcodec generic error: Xlib is required for VDPAU

That results in a fatal JRE error from ld-linux-x86-64.so.2+0xcc78.

It happens when a video stops playing. Whether as a song background or just a video on loop or not. As a song background or as a video on loop, it crashes right as it is about to loop.

Now my setup is kinda weird. It's my laptop running Ubuntu Server (focal), and I've manually added the needed display software for x11. I'm not sure if I'm missing something that causes this or if this is the same error you get.

[quelea-bot]

The error I get is also in ld-linux-x86-64.so.2+0xcc78 - I don't get the Xlib warning though so not sure if that's related, or a red herring. Regardless, thanks very much for the confirmation and I'll keep digging.

That could be specific to my setup.

[HeyITGuyFixIt]

@berry120 any updates on this?

[quelea-bot]

Afraid not (at least not yet.) Tried a few things that made no difference, I need to put aside a solid block of time to take a look and unfortunately things are very busy here at the moment. Feel free to keep hassling me on it though :-)

[LAfricain]

Same issue.

[HeyITGuyFixIt]

@berry120 hassling you again, any updates?

[Waterkloof]

I also have this problem on Ubuntu 20.04 has anybody tested it on Ubuntu 22.04?

[helgeheo]

I think this is a common problem for all linux distros

[HeyITGuyFixIt]

@berry120 bugging you again. Can I help with anything?

[berry120]

Hey, sorry for the silence on this one - things at the "real job" have been rather busy as of late!

Current status is that I'm seeing if I can just bundle a pre-packaged release of VLC into Quelea rather than relying on a snap dependency, therefore sidestepping the issue that JNA seem to have when loading the universal binaries (I'm still not sure why this is the case.) That's proving annoyingly time consuming however. I'll post back when I have a more concrete update.

On Ubuntu 22.04.1 LTS with the latest quelea edge snap:

• VLC plays a schedule video (added to the schedule using Add Multimedia)
• But when the video ends Quelea aborts and has to be restarted.
• Also, when during the video display a next schedule song item is selected and Go Live is pushed: Quelea aborts and has to be restarted.

[jeremehancock]

I just wanted to check to see if there had been any progress for this. I am hoping to include the Quelea Snap package in the UbuntuCE Software Center. I totally understand how it goes with balancing the "real job" and the passion projects. Believe me! :) Thanks for the hard work Quelea.

[berry120]

@jeremehancock No solid progress yet I'm afraid, I need to find another solid block of time to look at it, and time is proving hard to find at the moment!

Thank you for the update. I completely understand!

[berry120]

Taking another look at things I think we'll maybe need to look at bundling a version of VLC in the snap itself, so that's the approach I'll look at next. Have just wound back a bunch of experimental changes that I'd made in the hope that we could avoid this (in order to get a smaller & more efficient snap), but alas it wasn't to be.

[jeremehancock]

Fingers crossed. I appreciate the update. I really appreciate it.

[jeremehancock]

@berry120 Just wanted to check in on this. I see that there is a 2023.0 milestone. Thanks in advance

[juoliveiraneto]

Hello guys! I just wanted to check to see if there had been any progress for this.

[berry120]

Sorry for the delay everyone - we've now switched to GStreamer. This is still relatively new so there may be some issues, but initial testing seems to show that this works much better (at least on Windows & Ubuntu) than VLC.

I'll close this one now as we're no longer using VLC, but please do try the latest CI / edge release and open a new issue if there's any problems.
