Although this bug is only about decoding support, I'd like to leave a note about the rendering: AFAIK rendering without any slow copies requires DMABUF support, so processes can share resources on the GPU. For the Wayland backend this about to land, see bug 1552590, quote:
> Wayland dmabuf surface are located in GPU and can be attached as EGLImage or wl_buffer. It allows direct rendering to GPU and share the HW buffer across processes.
