This race condition is caused when one thread creates a swap chain,
which calls OBS_CreateSwapchainKHR, at the same time another thread
calls OBS_CreateImageView.
OBS_CreateSwapchainKHR allocates swap data, publishes this into the
data->swaps linked list, then initializes it. Meanwhile,
OBS_CreateImageView is iterating the swaps linked list, to see if the
image matches any swap chain images. Due to the order in
OBS_CreateSwapchainKHR, there's no guarantee this data is initialized
so it often ends up running out of bounds on the swap_images array.
The fix is simply to defer the swap data publish to after init.
Our solution for adding TRANSFER_SRC usage for imageless framebuffers
was triggering validation errors when combined with image view usage
overrides. Add TRANSFER_SRC onto usage overrides for swap chain image
views to fix mismatches.
Applications that use this Vulkan extension would have image usage
mismatches because we add VK_IMAGE_USAGE_TRANSFER_SRC_BIT to
VkSwapchainCreateInfoKHR::imageUsage, so make the same modification to
VkFramebufferAttachmentImageInfo::usage.
When changing a subproject (e.g. graphics-hook), the generated binaries
are not installed without also building win-capture. This commit enables
the subprojects to be treated as "plugins" which are installed to rundir
and also the installation directory without any additional workarounds.
The `add_target_resource` function uses unnecessary path components
when copying files to the rundir, resulting in files added that way
not to end up where OBS expects them to.
The generated binaries created by sub-targets also need to be copied
as part of `win-capture`'s data files, which was easy to fix as the
target exists before CMake switches into the subdirectories.
Doesn't make sense to grab the oldest frame when not capturing overlays,
because the overlay was already rendered in it. This will grab the
latest frame (before the overlay is rendered).
Use D3D12_RESOURCE_STATE_PRESENT for CreateWrappedResource arguments. We
should assume the application will set the backbuffer to PRESENT, and
expect that to be preserved across the Present() call.
Remove unnecessary calls to ReleaseWrappedResources.
Clean up (void**) casts with modern patterns.
