Explicitly query supported DMA-BUF modifiers from the compositor and use them when creating GBM buffers. This fixes capture failures on Sway when using the Vulkan renderer, which rejects the implicit INVALID modifier.

This is continuing to work well for me. I'm not sure when I should remove the DRAFT designation. Any input from maintainers? |
If you think it's ready for review or close to being mergable, you can remove draft. Typically I don't really review anything that's in draft unless asked, just because there is so much to review already. And with that said, I don't really use Linux myself so would appreciate anyone of the other contributors also reviewing and/or testing the changes. |
Considering I relied heavily on Gemini to create this that would certainly make me much more comfortable. I'll take it out of draft though. I'm happy with the results personally, and if/when HDR support gets merged for Sway it would be nice to have this working as it relies on the sway's vulkan renderer. |

Can you provide more precise instructions to test this PR? For me build from pipeline doesn't work at all on headless sway instance on Arch. Both with and without Vulkan. Upstream builds work without Vulkan, but don't work with it. Also it might be more beneficial to revive this PR: #4788 which implements more modern capture method. |
|
For my testing I cloned the pacman-repo repository and edited the PKGBUILD to use my repo and branch, then installed with makepkg and pacman. I've been testing on headless sway as well, using the WLR_RENDERER=vulkan variable. I verified that the env variable is set in the headless sway session from the terminal. |

Yes, I've installed build from PR pipelines, but it doesn't work both with and without Vulkan. I've attached the log. Is there any reason to try to build it from PKGBUILD of cloned repo? There might be additional problems, because I'm running it inside of Proxmox container, but this setup works without Vulkan. |

I've tested the build from the PR pipeline (Archlinux + wlroots-git commit 7265a79e + sway-git commit e51f9d7) for about an hour with WLR_RENDERER=vulkan. Notably HDR still doesn't work, I think it's not yet supported by the wlroots headless backend based on this log from sway: |
I didn't attempt HDR support in this PR. I'm not entirely sure it's possible in sway yet? I think sway-git might have added some support but I'm not sure It would work with the screen capture method being used. Someone can correct me if I'm wrong there. |
Sway 1.12 just released with HDR support, but yeah, I don't think it's possible with the wlroots headless backend (the log I posted is just from Sway, before even starting Sunshine). I just mentioned it in case people were following this PR for this reason, I doubt anything can be done about it until wlroots supports it. |

@joeknock90 could you fix the lint errors? https://github.com/LizardByte/Sunshine/actions/runs/26135435165/job/77045005439?pr=5132 |

I believe that clang-format was just looking for a space? Pushed and rebased. |

DISCLAIMER: I am not a developer, programmer, or really any sort of smart person at all. I punched this issue into Gemini-CLI. I manually approved all of he changes it made with very little understanding of them, but did learn a little bit. Never thought I'd be a vibe coder 🤮
For full transparency, here is the prompt I used:
I am currently testing my branch and it seems to be working well for me so far.
