Note: it would be nice at some point to have a selection switch
--use-vda=exynos|omx|libva|dxva|... like we have --use-gl, rather than an
explosion of switches with undocumented precedence as we add more paths. Not
necessarily for this CL, but maybe as a follow-up?

This is just a temporary flag, which I intend to remove as soon as we finish the
switchover from sec_omx.
