Can't launch games with obs-gamecapture %command%

[arnogon]

SteamOS 3.4.4 on Steam Deck. Installed OBS, OBS plugin and capture tools from Flathub. OBS now shows 'Game Capture', but games don't launch when I put obs-gamecapture %command% in the launch options.

[arnogon]

Okay. I have since built obs-gamecapture and put it somewhere in PATH. Now games do launch in desktop mode (with obs-gamecapture %command%), but OBS game capture still can't see them; and I still can't launch games with the launch options in game mode.

[nowrep]

Please post logs from both OBS and the game itself.

2023-01-10 21-26-41.txt Where can I find the log for a game?

[nowrep]

PROTON_LOG=1 %command% if trying with Steam games - log will be in your home directory.

[arnogon]

2023-01-10 23-14-26.txt steam-637650.log In game mode the game doesn't launch and there's no Steam log. These are the logs when tested in desktop mode.

[nowrep]

I don't see the game being launched with capture enabled at all in the log. env OBS_VKCAPTURE=1 %command% please see README.

[arnogon]

The logs above were generated with launch options set as 'obs-gamecapture PROTON_LOG=1 %command%'. 2023-01-10 23-52-15.txt steam-637650.log These logs are generated with launch options 'env OBS_VKCAPTURE=1 PROTON_LOG=1 %command%'.. This time the game can be launch in game mode. Please let me know if there's any problem with my launch options.

[nowrep]

You are not running the game with capture enabled: Command: ['/run/media/mmcblk0p1/steamapps/common/FINAL FANTASY XV/ffxv_s.exe']

I’m afraid I don’t understand. Should I change the launch options?

[nowrep]

Try with env VK_LOADER_DEBUG=all OBS_VKCAPTURE=1 PROTON_LOG=1 %command%, it will show why it's not loading vkcapture.

steam-637650.log In Gaming Mode with env VK_LOADER_DEBUG=all OBS_VKCAPTURE=1 PROTON_LOG=1 %command%.

Are you using flatpak steam? Also please just test with vkcube first OBS_VKCAPTURE=1 vkcube.

[arnogon]

Are you using flatpak steam? Also please just test with vkcube first OBS_VKCAPTURE=1 vkcube.

No not Flatpak, it's just the built-in Steam. 2023-01-11 17-05-34.txt Testing in Desktop Mode.

[nowrep]

Please post output of VK_LOADER_DEBUG=all OBS_VKCAPTURE=1 vkcube

[arnogon]

vkcube.log Tested in Gaming Mode.

Alright so it's back to my first reply https://github.com/nowrep/obs-vkcapture/issues/130#issuecomment-1375609155

For capturing games outside Flatpak runtime, you need native build regardless of if you are using Flatpak OBS or not.

If you are on steam deck you should be able to just install obs-vkcapture-git from AUR.

As mentioned I'm now used my own build, so this shouldn't be a problem.

However I just found another problem: PATH in Gaming Mode is different from that in Desktop Mode so my obs-gamecapture wasn't actually there. With that fixed this is the new log. vkcube.log Does that make a difference?

Also I'm aware that I could install it from AUR, but root partition in SteamOS is read-only and I'd rather not break the seal.

[nowrep]

You also need to move the layer json to a path where the vulkan loader will find it. Just install it from AUR.

[arnogon]

Okay, moved the json file to the corresponding path, now OBS recognizes the program and has the correct dimensions for it. But the screen is still black. Here are the logs: 2023-01-11 19-51-24.txt vkcube.log

[nowrep]

Same issue as #127 - try adding OBS_VKCAPTURE_LINEAR=1.

[arnogon]

Thanks, now it works with some games. But for other games, OBS is still not picking the window. 2023-01-11 20-33-09.txt This particular game isn't run through Proton so PROTON_LOG=1 doesn't seem to generate log.

[nowrep]

If it's a Vulkan game, see why the layer didn't load. If it's an OpenGL game, you need to run it with obs-gamecapture ...

[arnogon]

How do I tell if a game is Vulkan or OpenGL? Also I ran it with obs-gamecapture too, but OBS didn’t see that either.

[arnogon]

portal2.log Managed to get the log. I think Portal 2 is Vulkan.

[nowrep]

You also need to install 32bit vkcapture.

[arnogon]

Is that something I can get from Flathub or should it be in my build as well?

[nowrep]

You need to build it yourself.

[arnogon]

I have now built obs_vkcapture_32.json, but don’t I need the 32-bit version of libVkLayer_obs_vkcapture.so as well? Right now I only have the 64-bit version and it’s provided by the Flatpak. I don’t think there’s a i386 version of the plugin on Flathub though.
