Some frameworks (EFL) expect BGRA textures for storage. However, adding support for that broadly into GStreamer framework implies two kinds of hacks: (i) libgstgl helpers currently do not support BGRA textures correctly, (ii) we need to better parse downstream suggested caps and intersect them with what the VA plugin elements can offer to them for GL texturing.
