AW: why timeoverlay doesn't work

[Thornton, Keith]

Textoverlay works for me on windows. I do set some parameters
             g_object_set(G_OBJECT(m_pFrameCountOverlay), "valignment", 3, static_cast<char*>(nullptr));
        g_object_set(G_OBJECT(m_pFrameCountOverlay), "xpos", 0.5, static_cast<char*>(nullptr));
        g_object_set(G_OBJECT(m_pFrameCountOverlay), "ypos", 0.7, static_cast<char*>(nullptr));

I also use timeoverlay
        g_object_set(G_OBJECT(m_pTimeOverlay), "font-desc", "Arial        g_object_set(G_OBJECT(m_pTimeOverlay), "xpos", 0.5, static_cast<char*>(nullptr));
        g_object_set(G_OBJECT(m_pTimeOverlay), "ypos", 0.3, static_cast<char*>(nullptr));
normal 18", static_cast<char*>(nullptr));
        g_object_set(G_OBJECT(m_pTimeOverlay), "halignment", 1, static_cast<char*>(nullptr));
        g_object_set(G_OBJECT(m_pTimeOverlay), "valignment", 3, static_cast<char*>(nullptr));
but I havn’t tried clockoverlay

Not sure about dshowvideosink, but clockoverlay and textoverlay uses cairo to draw test.
Cairo in turn uses pango to lay glyphs on buffers.

Are pango and cairo working on your system?

I'm not sure how to test them on Windows.
