Still not able to use Nvidia NVENV codec

[Yorisoft]

Still getting this error when using this OBS :/

Using driver 470. Nothing else running besides webcam and capture card.

Can I have a look at your encoder settings in OBS? I'm pretty sure you'll have to turn off some options there for this to work. I should probably document this as well...

[Yorisoft]

What settings would you recommend changing?

Im outputting at 1080@60.

[guihkx]

Im outputting at 1080@60.

That's only the resolution, and it shouldn't matter much, I think.

Also, that screenshot seems to be from a much older version of OBS?

Anyway, I'm talking specifically about these options:

Try to match yours with these and try again. If that still doesn't work, please run OBS from the terminal, try to record/stream, and share the output here:

$ flatpak run com.obsproject.Studio
...

[Yorisoft]

You're right! Sorry about that, forgot I went live with another OBS

This is my settings for your project version:

Going to try to match those settings now.

[Yorisoft]

It worked! Thanks a ton!!

I changed my setting to match those you showed and now it works as intended.

[guihkx]

Awesome! :)

I'll leave this open until I properly document this somewhere.

[Yorisoft]

Would there be any issues when using this with multi-rtmp?

My stream keeps crashing now but I cant tell whats the cause.

[guihkx]

Would there be any issues when using this with multi-rtmp?

I'm not sure, I never used that plugin.

Can you share the output from running OBS in the terminal? There might be something useful there.

Also, does it crash with local recordings?

[Yorisoft]

When using these plugins my workflow is, start streaming through OBS controls start multi streams through plugin controls Finally, stop main stream from obs controls

Judging by the logs, and if I had to guess, I'd say you're suffering from VRAM exhaustion.

Are you streaming some type of heavy, 3D game?

Anyway, if you want to be sure that's the root cause of the problem, open NVIDIA X Server Settings, start recording on OBS, and monitor VRAM/Video Engine Utilization, i.e.:

If that's indeed the cause, I'm afraid you'll have to try t lower your encoder settings further.

[Yorisoft]

It doesnt look like the consumption is going past 65%

[Yorisoft]

I did lower the encoder settings. That seems to help but it didnt resolve completely. It lasted a few seconds longer but eventually also crashed.

[guihkx]

I see... What about Video Engine Utilization, though? In your screenshot it's already at 0%, which doesn't tell me much.

Start recording/streaming, and then immediately look at NVENC usage.

I'm guessing the encoder is bottle-necking at 100%, and then OBS stops the stream because many frames were lost.

[Yorisoft]

Yes, that seems to be the case

[guihkx]

Yeah, that's unfortunate.

It seems like your native screen resolution is way larger than 1920x1080 (perhaps 4K?), and so the encoder grabs the frame in the original resolution, and then downscales it to 1920x1080, which might be contributing to the bottleneck.

I'm not sure what would be the best option for you, but if you can, perhaps set your display's resolution to 1920x1080 when you're streaming/recording.

But we have to keep our expectancies in check, too. We're talking about a GPU from 2012 here... :P

[guihkx]

What if you didn't do any downscaling in OBS at all?

Wouldn't Twitch (and other streaming services) downscale it automatically to lower resolutions? That could reduce the bottleneck in the encoder, maybe.

[Yorisoft]

Just tried doing that. No luck.

Seems that the GPU can support multiple rtmp feeds but it cant handle the Vertical Canvas. It alone pushes the Video Engine Utilization to 95%.

[guihkx]

Oh, damn. I don't know what that plugin does, but I assume it must be important for you.

Did it use to work just fine with previous versions of OBS on that same GPU?

[Yorisoft]

This Vertical Plugin allows you to create a Vertical Scene and Stream it to platforms at the same time you do your normal stream.

Tbh, Ive never got it working on this GPU. The OBS version that supports this plugin did not support dedicated encoding on my GPU so I stuck to OBS 27 and not use to plugin. But would love to.
