This specific test triggers a bug in GStreamer HEVC parser, I'm aware of this
one, and it is on my todo to fix (just not as trivial as it looks like, the VCL
nal detection code was implemented wrong and that ended up leaking into the rest
of the design). This specific test will of course be marked and skipped for CI
test that uses GStreamer.

Nicolas
