Maps GstVideoFormats to suitable DRM fourccs which work with glcolorconvert, using gst_gl_memory_alloc(). We require mostly only 4 formats to be supported by the driver. We require DRM equivalent to RGB16, RGBA, R8 and RG88. This way it's compatible with DesktopGL, since GL_TEXTURE_2D is used and limit driver requirements. With this we can virtually support all formats the glcolorconvert supports. https://bugzilla.gnome.org/show_bug.cgi?id=743345
