I am working a lot with videos using a gstreamer based subtitle editor called subtitleeditor (compiled from upstream, ubuntu's version is horribly outdated) and it can play the videos, but with terrible performace (lots of stuttering, sometimes it skips 30 frames or even more before continuing to play). Removing gstreamer-vaapi solves it too.
