Question / Help OBS Studio AMD VCE won't record unless downscaled.

[Arcanekitten]

I want to use obs to record something and use amd vce else I get very poor framerate.

But when I try to start recording I doesn't do anything it just sits there doing nothing and what fixes it is if I downscale the image from 2560x1080 to 1920x1200 or lower anything above that It ain't work.

So I pull up the logs and see this error which I can't really make anything out of except it has some kind of error with the output res.



And to clearify I have tried a lot of things and it tries multiple times before failing.

Log is incomplete.

Also, don't use the Media Foundation implementation of VCE, look for the plugin made by Xaymar.

@Harold Sorry thought that was enough.

 

[Arcanekitten]

@Fenrir yh but it crashes when I try to record I will try to give a log.

@Harold @Fenrir Here is the crash log from the Xaymar VCE mod.

You do not have a 3rd Generation GCN card, so the maximum resolution hardware encoding can do for your card is 1920x1920.

Upgrade to a 3rd Generation GCN card if you want to record/stream using your hardware at 4K for example. I have a full list of those cards here: https://github.com/Xaymar/OBS-AMD-Advanced-Media-Framework/wiki/Hardware,-GCN-and-VCE-Limits

Wow never knew this and I can't seem to find it online but it does make sense now I know this, sadly I have a 2560x1080 screen so it's kind of annoying (paired with r9 290)
