We plan to replace labels with media_codecs.xml (http://crbug.com/663285). So hardware_VideoDecodeCapable won't be needed.
hardware_VideoDecodeCapable is not running on any device because no device has vaapi or video_decode_v4l2 labels. I looked at the checked formats in the test and it's not up-to-date for all devices. Also, Nvidia tried to run the test and it failed because nyan doesn't use v4l2 devices. We should remove the test to avoid confusion.
