The H/W video decode codepath in Chromium does not have layout tests to help catch
issues like the one here https://bugs.webkit.org/show_bug.cgi?id=91562

A possible approach mentioned by Adrienne Walker

You could either explicitly enable the hardware video path via a new function in Chromium's LayoutTestController.cpp (look for how we handle loseCompositorContext as an example).  Alternatively, you could create a (hypothetical) LayoutTests/platform/chromium/compositing/hardwarevideo/ directory and then modify TestShell::runFileTest to set these flags on anything in that directory.

Then I think you could just take a basic video layout test and run it through the hardware path.
