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horribly outdated) and it can play the videos, but with terrible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.

Bug description:
  If gstreamer-vaapi is installed Totem fails to play anything, and instead just shows an error popup saying "GStreamer encountered a general stream error". The app doesn't produce any error msg on the terminal, but shows that vaapi is being used:
  ...

  Gst-launch using vaapidecocde and vaapisink still works properly,
  using

  gst-launch-1.0 filesrc location=bbb_sunflower_2160p_60fps_normal.mp4 !
  qtdemux ! vaapidecode ! vaapisink

  takes 6% cpu instead of 300% on my broadwell based laptop.
