 Under most circumstances, VAAPI can only be used for the first video
 opened. If another video is opened right after (like when using live TV
 and changing channels); then VAAPI will not be used.

 Instead VAAPI display creation will fail with an error and decoding will
 default to ffmpeg for following videos.

 Error displayed is:
 "Already have a VAAPI display of a different type"

 Reason is that to detect VAAPI availability, a temporary VAAPI display is
 created with the type X11 when there's already an OpenGL one being used.

 The VAAPIDisplay shouldn't be re-used when we're only trying to check
 VAAPI capabilities
