VLC crashing on playback

BollerwagenPicard · 2022-12-03 13:05:11

Hi all

I have a problem with my setup.
When I try to start a video in VLC it crashes. I do not know why and need your help. As I do not watch videos from HDD that often, I can't say if it is connected with one of the updates I did.

vlc --reset-config --reset-plugins-cache -v
VLC media player 3.0.17.4 Vetinari (revision 3.0.13-8-g41878ff4f2)

Is that output supposed to be related to such crash or just from a re-caching run?

Do you have a coredump?

Edit: faulty hw decoder?

it is a output of the VLC started via ZSH from start to the crash. I opend the file in VLC GUI.

It lists only a coredumps of firefox for today... but I had no problems with firefox.

seth · 2022-12-03 14:47:38

VLC_VERBOSE=3 vlc --reset-config --reset-plugins-cache

and trigger the crash.

BollerwagenPicard · 2022-12-03 15:13:08

you can find the output at https://paste.3server.de/?bcf54cbfb962f … jBGyCh33A6
I hope a past bin is okay for the long log.

How does this crash? Does the vlc processs terminate or does only the video not play?

[00007fac8b065890] avcodec decoder debug: trying format vaapi_vld
…

See the edit in #2, link and please post the output of the three commands.
Also try to configure VLC to use vdpau, https://wiki.archlinux.org/title/VLC_me … celeration

No audio starts... I get a very short black screen in the VLC window and after this it terminates.

It was set to auto... I changed it to vdpau for the test but same problem.

08:01.0 VGA compatible controller: Matrox Electronics Systems Ltd. MGA G200eW WPCM450 (rev 0a)

Is that actually there?
Does it show up in your xorg log?

What if you "export VDPAU_DRIVER=nvidia; vlc video.mp4" (w/ vlc configured for vdpau)
And as a sanity check: download some h264/mp4 video from youtube (w/ yt-dlp) and try to play that (to make sure it's not the video)

I think it is the "GPU" of the motherboard and the remote management... it is a server board.

2 cards showing up in the logs... I'm not sure if this one but 2.

No change to the error

I checked old files that have worked in the past and that new file (downloaded by yt-dlp) which I noticed the error with.

At this point, thank you again for going through this with me.

seth · 2022-12-03 17:19:52

Sanity check: disable the HW acceleration. Does the video play?
Does the video play in mpv?

No, it does not play it

seth wrote:

yes mpv does play it

also firefox can play the video (HW acceleration is on in firefox)

If you're on Nvidia, try downgrading the drivers e.g. to the previous 520.56.06 version. I had the exact same issue and downgrading solved it; I guess it's some new quirk of the latest drivers that VLC is incompatible with.

seth · 2022-12-03 20:21:59

The OP is - did you get some more informative coredump for this crash?

Nocifer · 2022-12-04 15:06:21

Here's a tracelog: https://paste.apexnode.dev/?e0ea7c89978 … Ro5eDjfZhc

I can't really make heads or tails of it, but at least I can confirm that downgrading to the previous Nvidia drivers "fixes" the issue. Also, as in OP's case, I can play video just fine with mpv, ffmpeg and Firefox, so I still think it's probably an incompatibility with either VLC's libplacebo or maybe Qt itself.

Why and how the glx code triggers a (likely) threading bug in VLC, idk. - though maybe it's just a follow-up bug (the video fails and triggers an unpredicted race in the VLC GUI code where it relies on some playback activitiy for the GUI animation)

Can you play the video w/

vlc -I ncurses

?

I haven't yet dared to do the driver downgrade due to lack of experience.

gitkraken is gtk3, so it's probably not a Qt issue.

https://wiki.archlinux.org/title/Arch_Linux_Archive
As long as you're still on linux 6.0.10.arch2-1, you can downgrade to 520.56.06-12
Edit: nvidia and nvidia-utils together.

OK, I found the culprit, at least in my case. I noticed a bunch of Firefox coredumps from within the past few days that point to issues with libva, and I remembered that I've been using libva-nvidia-driver for a while now in order to get Firefox's HW acceleration to work with Nvidia via VA-API. I disabled that (i.e. uninstalled it, because for some reason VLC will still crash when it's installed even with HW acceleration explicitly disabled or set to VDPAU) and sure enough, VLC is working again.

I also checked upstream's github, and found this: Issue after upgrading to 525 series drivers. It seems it has been a kind-of-known issue since the 525 beta (kind of, because there are no libplacebo crashes reported, in fact there is even mention of using that as a testbed).

OP, could you be using this third-party driver as well? I'd guess you do, seeing as you've mentioned that you have Firefox on Nvidia with working HW acceleration. And I just noticed that you also mentioned seeing a bunch of Firefox coredumps...

Fixed it for me with a change to libva-vdpau-driver
