It seems that it conflicts with MediaOzonePlatform. For example, when
use_ozone=1, it will never use MediaOzonePlatform since it will meet the
condition defined(OS_CHROMEOS) && defined(ARCH_CPU_X86_FAMILY). This CL's target
is making Vaapi accelerator work with ozone. So maybe you can further abstract
it to work with wayland. In that case, We can remove MediaOzonePlatform
directly.

Wayland builds for desktop (chromeos=0) and should hit the correct path.

   video_decode_accelerator_.reset(new VaapiVideoDecodeAccelerator(
-      glx_context->display(), make_context_current_));
+      stub_->decoder()->GetGLContext(), make_context_current_));
 #elif defined(USE_OZONE)
   media::MediaOzonePlatform* platform =
       media::MediaOzonePlatform::GetInstance();
   video_decode_accelerator_.reset(platform->CreateVideoDecodeAccelerator(
       make_context_current_));
   if (!video_decode_accelerator_) {
     SendCreateDecoderReply(init_done_msg, false);
     return;
   }
