In general, we ask submitters to share a fluster [0] score (this is just to
demonstrate that the integration has been well validated). LibreELEC community
have patch to enable this ffmpeg fork. I don't expect any surprise here, and you
can just reply to my email here.

Alternatively, this test tool is shipped in latest Debian, and with the
appropriate GStreamer packages you'll be able to run the VP8 and H.264 tests.
