Browser source doesn't show anything with some versions of CEF

CEF builds that are working properly:

• 3.3440.1805
• 3.3440.1803
  ...
• 3.3359.1769
• 3.3325.1750

If you have successfully run obs-linuxbrowser with other CEF builds, we'd be glad, if you'd post them in this thread so we can add them to this list.

I think at some point I updated / recompiled OBS Studio from source and the linuxbrowser plugin stopped working for me and I simply don't see the browser source in the preview area. In the past I may have just had to recompile the plugin and CEF again, but not having that luck this time. Any ideas what might be wrong?

OBS log file: https://hastebin.com/oronevikac
Additional error in terminal: https://hastebin.com/omegukokuq.m

OS: Arch Linux
obs-studio-git 21.1.1.r93.gb41ca1ca
obs-linuxbrowser 0.3.1-1 (Just recompiled now, so commit 2b0319a)
cef-minimal 3.3359.1772.gd1df190-1

edit: Appears to be an issue with recent versions of CEF, actually. No issues when using 3.3325.1750.gaabe4c4.

I have the exact same issue. I tried to downgrade to 20.0.1 just to see if that fixed the problem. No luck

Hello. Unfortunately I don't really understand what happened. Could you try uninstalling linuxbrowser packages and manually ~/.config/obs-studio/plugins if there are any files there.
Then installing that aur package again or just building yourself?

@bazukas I tried this way many times and it's not working.

[bazukas]

@NexAdn could you please try to reproduce this error, unfortunately I no longer have an arch system

[yurwpjt]

@bazukas Where are you from? (don't reply if too personal) If we're in the same country you or your friend can tell me the solution in our language.

[bazukas]

@yurwpjt there is no solution yet, we're trying to figure it out

~/.config/obs-studio/plugins does not exist. obs-linuxbrowser installs to /usr/lib/obs-plugins/obs-linuxbrowser.so and /usr/share/obs/obs-plugins/obs-linuxbrowser/. After removing the package, those files are gone. Had no luck with reinstalling.

Alright, I installed an old version of the cef-minimal package, version 3.3325.1750.gaabe4c4 from 2018-03-18 instead of 3.3359.1772.gd1df190. That ended up working out for me.

[bazukas]

@copygirl thanks for the info, seems like the problem lies in certain versions of cef

[yurwpjt]

@copygirl Worked for me, ty dude

[RedLionhead]

I just removed cef-minimal completely and that fixed my issue

I encounter the same problem when installing some specific CEF builds, but I didn't figure out what makes CEF crash, neither did I figure out if the browser is crashing or if the rendering engine is not working correctly. The latest version that worked for me was 3.3359.1769.gd0bfc4d if I remember correctly (I am not on my desktop right now so I can't verify).

If I encounter this problem again, I could try to debug it.

EDIT: When using 3.3359.1772.gd1df190 all browser processes seem to crash. Neither OBS log gives any information about the crash, nor does any source-specific obs-linuxbrowser log (under .cache/obs-linuxbrowser/.../, being completely empty. @bazukas are there any other log files I could look into to maybe find the cause of the crash?

Obviously the crash seems to happen at a very early stage. When restarting the browser via the menu button in the source config, htop shows a browser process for one tick and then it seems to crash. After that, there are no instances of browser-subprocess or browser, but just obs.

EDIT 2: Okay, the last one appeared when I was using a global install of obs-linuxbrowser (AUR) having it compiled with3.3359.1769.gd0bfc4d and using a provided 3.3359.1772.gd1df190 cef-minimal in /opt/cef (AUR). I just installed obs-linuxbrowser locally and it gives me similar output as OP uploaded. All browser and browser-subprocess instances seem to be running, but not working. The debug.log file in the binary directory (.../bin/64bit/) has these contents:
