obs-vkcapture VS obs-gstreamer

I can't speak for Chrome nor VMWare, but Firefox and OBS have received "Wayland native" screen capturing functionality, through XDG portals and Pipewire, as far as I'm aware.

As a side-note, I've recently discovered a really cool project[0] that enables incredibly fast screen capture for OpenGL and Vulkan applications, mostly tailored to games. Tried it with a bunch of stuff and it works much better than both X's and Pipewire's screen grabbing. I can actually capture videos at my monitor's native refresh rate (144Hz).

Hello, so I use this OBS plugin obs-vkcapture. I use it as opposed to the built-in Window Capture, because with that option I would keep having to alt-tab back into OBS to select the game I want to record. This plugin is basically the "Game Capture" feature on OBS Windows brought to Linux. It makes it to where I can put a Steam launch option obs-gamecapture %command% and launching the game will make its executable show up in the Game Capture source, so I can just press record on move on, no more opening OBS to select the game's window and risk nuking it when alt-tabbing. It is much more performance efficient and it's a package/patch that is included in GloriousEggroll's Nobara distro's build of OBS as well. I however use it on Arch from the AUR, it's the only AUR package I use in fact.

I was using https://github.com/nowrep/obs-vkcapture but I also had Proton-GE 7-49

Back in december when I tried I had some success using this https://github.com/nowrep/obs-vkcapture

Additionally, I'd like to use Game Capture in OBS if possible via obs-vkcapture. If using this with gamescope, where do I actually put the variable or obs-gamecapture command? Does it wrap the entire gamescope command, or does it get wrapped by gamescope?

I think you mean obs-vkcapture-git. It lets you capture a window through Vulkan. Here is also its github repo for more informations.

I have spent a few hours trying all kinds of dependencies on Fedora 36 Workstation trying to get obs-vkcapture to compile. I have found the exact ones and hopefully it helps someone in the future: cmake gcc gcc-c++ obs-studio-devel mesa-libGL-devel vulkan-loader-devel Here is a convenient command to install all at once: sudo dnf install cmake gcc gcc-c++ obs-studio-devel mesa-libGL-devel vulkan-loader-devel

I'd recommend you to look for obs-vaapi and obs-gstreamer as plugins to utilize GPU encoding on OBS. On Flatpak they're available as OBS plugins you can install alongside the Flatpak version of OBS.

I wanted to start experimenting with GPU recording on my Ubuntu machine and saw this video from GloriousEggroll demonstrating VAAPI working better than ever using the obs-gstreamer plugin, which would now be the standalone obs-vaapi plugin. I'm running Ubuntu 22.10 and the latest stable version of OBS from the ppa. As instructed, I checked the VAAPI version on my system with vainfo, got this.

On Nvidia you'd use obs-gstreamer (it's the same but obs-vaapi has only the vaapi part, not the entire implementation) because vaapi isn't supported by Nvidia.

Plus, since my Crysis 3 gameplay I'm using obs-gstreamer which fixed the crappy ffmpeg performance while recording with hardware encoding.

Try obs-gstreamer plugin... I'll write the easy way tomorrow if you don't know how to compile and install it, but if you can read then it's fine

Use obs-gstreamer https://github.com/fzwoch/obs-gstreamer

The video description is a bit misleading. You need this OBS plugin in addition to installing gstreamer-vaapi.
