Recording NVIDIA NVENC AV1 not showing up as option?

[DaReaLDeviL]

Hello,
I just wanted to test out my new 4080 with OBS and recording. But in the dropdown menu it only shows AOM AV1 and no NVIDIA NVENC AV1 option.

Is there a dependency on when it is shown or do I miss some special settings? Colorsettings, Windowssettings, etc

Windows 11 pro - 22H2
NVIDIA - 531.18
OBS - 29.0.2

Please post a log with your issue! Here's how...

OBS Studio creates a log file each time you run it which contains very useful diagnostic information. Without a log file, it's much harder for any support volunteers to figure out problems and your post may be ignored. To upload a log file, go to the Help menu > Log Files > Upload Last Log...

Any Ideas from anyone please?

Please read and follow directions and recommendations on the analyzer:

Analyzer | OBS

OBS (Open Broadcaster Software) is free and open source software for video recording and live streaming. Stream to Twitch, YouTube and many other providers or record your own videos with high quality H264 / AAC encoding.

Also check the plugins for updates or completelly remove them if any of them is not updated to work with OBS 29+.
And for the log, a test recording of at least 30 seconds is needed.

Make sure you have the latest nvidia driver. Do not trust windows update for it. Use either nvidia experience or directly from the nvidia website.

@PaiSand thank you for the replay. Is there an easy way to get rid of all plugins? Maybe there are some old leftovers. How do I find them?

 

[PaiSand]

Most plugins are simple, you just need to delete the files in the plugin folders:
C:\Program Files\obs-studio\obs-plugins\64bit (the dll file)
C:\Program Files\obs-studio\data\obs-plugins (other files)

Some other plugins need to be uninstalled with the uninstaller they provide, like streamelements. But it also uses %appdata%\obs-studio\ path to store other files and configurations which aren't removed when you uninstall the plugin. StreamFX also uses this path.

You don't need to remove all of them. Just the old ones (not updated) or those you don't use.
Make sure you first removed any reference to them in the scenes and sources.

@DaReaLDeviL Did you find a solution for this? I'm experiencing a similar issue.

 

[DaReaLDeviL]

Nope not - but I just had time to dig deeper now :/ but still testing with no positive result :( @pleythru

 

[R1CH]

Can you try running the test directly from cmd prompt, e.g:

C:\Users\Richard>cd C:\Program Files\obs-studio\bin\64bit

C:\Program Files\obs-studio\bin\64bit>obs-nvenc-test.exe

 

[DaReaLDeviL]

@R1CH

C:\Program Files\obs-studio\bin\64bit>obs-nvenc-test.exe
[0]
is_nvidia=true
supports_av1=true
[1]
is_nvidia=false
supports_av1=false
[2]
is_nvidia=false
supports_av1=false

Is there anything else I need to add? This outcome tells me nothing :/

 

[R1CH]

For some reason OBS itself is unable to run that program, so it can't tell which devices support NVENC. Could you try removing any 3rd party plugins?

 

[DaReaLDeviL]

This is not an easy task. Can I just save an entire folder as a backup and install it from scratch then?

 

[R1CH]

Yes, you could also download the .zip version and run it in portable mode (though some globally installed plugins may still load).

 

[DaReaLDeviL]

Ok things make no more sence for me. I downloaded the zip and started the 64bit obs exe from them with a shortcut and --p.

It loaded my profile and settings right out of the box and now I can use the nvenv av1. But how do I get it to work with my original installed version?

 

[rockbottom]

R1CH already told you it was a plugin in his 2nd post. Not to hard to figure out what needs to be done.

 

[DaReaLDeviL]

@rockbottom sorry I don't understand why it loads all my settings when I use files from a unzipped folder with a portable start link that are not linked to any installation.

All my plugins are loaded. And yes you are right, and R1ch also. It must be leftovers then.

 

[rockbottom]

Yes, you could also download the .zip version and run it in portable mode (though some globally installed plugins may still load).

 

[rockbottom]

I could be wrong but any plugins that loaded in the portable version should be OK since the AV1 encoder was exposed.

 

[R1CH]

Portable mode shouldn't be loading your existing scenes and settings, it should be like a new install. The command line option is -p or --portable, it looks like you may be using --p instead. I notice now the page I linked has that error, I'll fix it.

It seems some plugin in your main install was responsible for the issue.
