+Subject: [PATCH] khronos: backport typedef for EGL_EXT_image_dma_buf_import
+
+The `gstreamer1.0-plugins-base` package version `1.14` uses `EGL_EXT_image_dma_buf_import`, which
+expects the `EGLuint64KHR` typedef that is present in recent versions of Khronos.
+However, the older version included in userland does not provide it.
+
+This patch backports the missing typedef from recent Khronos into userland.
+See: <https://www.khronos.org/registry/EGL/api/EGL/eglext.h>
+
+Submitted to userland in <https://github.com/raspberrypi/userland/pull/467>
+
+Upstream-Status: Submitted
