+wayland-egl (mesa EGL component)
+
+The Wayland display server protocol uses EGL. If you build qt5 with
+its optional dependency wayland and then build vlc then vlc will
+require wayland-egl.
+
+EGL is an interface between Khronos rendering APIs (such as OpenGL,
+OpenGL ES or OpenVG) and the underlying native platform windowing
+system. EGL handles graphics context management, surface/buffer
+binding, rendering synchronization, and enables "high-performance,
+accelerated, mixed-mode 2D APIs". EGL is managed by the non-profit
+technology consortium Khronos Group.
