Describe the Bug

Hey, great work on the new xdg desktop portal capture method backend. I have personally been waiting on this feature for quite a while. I just tested it out and noticed that it doesn't work on hyprland. I tested again on kde plasma and it worked perfectly. The only thing that stood out to me when checking the status of sunshine via systemd was the line Pipewire Error, id:2 seq:24 message: no more input formats.

I searched online for that particular error, but it seem to have drug up old issues regarding having the display set to 10 bit instead of 8. However changing to 8 bit did not fix the issue. I tried restarting all of the portal services as well as sunshine after doing so to no avail.

I know that screencasting works on hyprland via obs, vesktop, and the mozilla test page, but I can't seem to get sunshines implementation to work.

If there is any additional info I can provide. Please let me know.

If you can compile Sunshine yourself, try removing the DRM_FORMAT_ARGB8888 format from the array in src/platform/linux/portalgrab.cpp:

  static constexpr std::array<format_map_t, 3> format_map = {{
    {DRM_FORMAT_ARGB8888, SPA_VIDEO_FORMAT_BGRA},
    {DRM_FORMAT_XRGB8888, SPA_VIDEO_FORMAT_BGRx},
    {0, 0},
  }};

to:

  static constexpr std::array<format_map_t, 3> format_map = {{
    {DRM_FORMAT_XRGB8888, SPA_VIDEO_FORMAT_BGRx},
    {0, 0},
  }};

@psyke83 Unfortunately, that change did not appear to make a difference. I used the pkgbuild from nightly and changed the branch and commit to my branch and the commit I made that contained your change in order to test this out nicely.

Not sure if it helps, but hyprland actually lists the format being used for all display via hyprctl monitors. Right now I can see that the current format for my display is XRGB2101010 when set to 10 bit and XRGB8888 when set to 8 bit. I don't know much about pipewire or this code in general, but I can see that when set to 8 bit it matches the format in your array even though it still appears to not be working.
