From f6cf3a40e479b5f1e98b11cf6c816baf34cb3bac Mon Sep 17 00:00:00 2001 From: Lynne Date: Mon, 28 Aug 2023 22:20:45 +0200 Subject: [PATCH] vulkan: check for extension rather than function pointer The loader ensures only that functions with tagged supported extensions exist, rather than ensuring only those with supported extensions are loaded. As the init function uses Vulkan functions, whose loading requires them to have the extension flags set, the extension flags are guaranteed to also exist at this point. --- libavutil/vulkan.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/libavutil/vulkan.c b/libavutil/vulkan.c index 8e36ba508c..00a7b5b801 100644 --- a/libavutil/vulkan.c +++ b/libavutil/vulkan.c @@ -165,7 +165,7 @@ int ff_vk_load_props(FFVulkanContext *s) vk->GetPhysicalDeviceQueueFamilyProperties2(s->hwctx->phys_dev, &s->tot_nb_qfs, s->qf_props); - if (vk->GetPhysicalDeviceCooperativeMatrixPropertiesKHR) { + if (s->extensions & FF_VK_EXT_COOP_MATRIX) { vk->GetPhysicalDeviceCooperativeMatrixPropertiesKHR(s->hwctx->phys_dev, &s->coop_mat_props_nb, NULL);
