+Subject: [PATCH] {avcodec,tests}: rename the bundled Mesa AV1 vulkan video
+ headers
+
+This together with adjusting the inclusion define allows for the
+build to not fail with latest Vulkan-Headers that contain the
+stabilized Vulkan AV1 decoding definitions.
+
+Compilation fails currently as the AV1 header is getting included
+via hwcontext_vulkan.h -> <vulkan/vulkan.h> -> vulkan_core.h, which
+finally includes vk_video/vulkan_video_codec_av1std.h and the decode
+header, leading to the bundled header to never defining anything
+due to the inclusion define being the same.
+
+This fix is imperfect, as it leads to additional re-definition
+warnings for things such as
+VK_STD_VULKAN_VIDEO_CODEC_AV1_DECODE_SPEC_VERSION. , but it is
+not clear how to otherwise have the bundled version trump the
+actually standardized one for a short-term compilation fix.
+
+(cherry picked from commit e06ce6d2b45edac4a2df04f304e18d4727417d24)
