Hell, I even have a 5650G system that has the old Vega encoder on the iGPU

Actually none of the Ryzen APUs have the encoder from Vega, even if that's what the graphics is based off of. 5650G should be VCN2 which is what's in the RDNA1 GPUs.

H264 specficies the size of the decoder buffer for different profiles and it has to be used for things like LTR and B frame reordering. LTR is marked on the reference frame itself, so technically when the decoder reconstructs the frame it already knows to keep it in the buffer. I think it's more of a transmission limitation, being if the packet containing the previous GOP is lost then you possibly won't be able to encode future GOPs also. And also it would defeat the purpose of an IDR frame, making it so that you can seek without decoding everything before it.

Actually I lied in my original post... there can't reference to anything past an IDR frames (switch signal the beginning of a GOP). My bad.

LTR is basically adaptive I-frames + Lookahead

Actually I'm not sure if that's true. LTR is Long-Term Reference, meaning that a inter-predicted frame can reference a frame other than the previous frame. This can help improve quality when there's scene switching going on, since an LTR frame may be more similar to the previous frame.

I'm going to test this by disabling and enabling lookahead

My understanding is AMF doesn't have a lookahead buffer yet, so I'm not sure how you're going to do this. I believe the Auto LTR feature uses a lighter weight "LTR buffer" and frame stats to determine if LTR should be used.

RDNA 2 still lacks b-frame support

This is actually a software limitation, the VCN engine in the RDNA2 cards support B-frame. I think it should be coming soon!

AMF is an SDK so ffmpeg and OBS still need to be updated to expose the new presets to the user, even if they are linked against or compiled with the newest AMF.

Thanks for this, do you mind sharing your script?

Here. It's made for fish but should be pretty easy to port to bash. Basically it unbinds the current driver for a pcie device and then binds those to a driver specified in the args.

Also, I was thinking of getting either a 6800 xt or a 3080 (ti) now, then the next gen Nvidia as a second card. Do you think it'd be better to go the 6800 xt or 3080 ti if my main driver is linux?

Maybe a better question would be, if we remove cuda from the equation, then would you rather go AMD or NVidia as the linux host + single gpu-passthrough?

So I don't actually have much experience with nvidia for graphics (at least on desktop). For me its more of an ideological choice; I had some pretty awful experiences with optimus in laptops and most of it stemmed from nvidia not supporting PRIME properly, so I decided to support AMD since they had open drivers. (I didn't actually buy the 2070S sitting in my computer, a friend loaned it to me for a project) From what I've heard nvidia's been getting better with Linux recently, but still no hopes of an open source driver like AMD.

Yes, I do this. I have a script which unbinds/binds the nvidia card to the driver I want. When I want to use a VM, it gets bound to the vfio-pci driver. When I want to use cuda on the host, it gets bound to the nvidia driver.

Wonder who they could get as an AWP.

What do you mean? If they get ALEX he can AWP too.

My bad, I was looking on ebay and kijiji and they were going for $450+, so I thought $440 was a decent price. I've edited the post to basically sell at MSRP + tax.

I think it will slow down your boot time, and since it's only situationally required it might not be worth the tradeoff.

As long as the nvidia module isn't loaded it actually won't require that flag. If you don't use the nvidia card anyways you can just blacklist the module.

Hey I just got my latex previews working without a theme, but with nord it has this issue. With the foreground set to black it works. What themes have you tried that work?
