Description Kenta Ueda 2014-12-19 09:58:05 UTC

When wmv video was played with VAAPI on gstreamer and mplayer, green and pink color is shown in the video screen.
If disabled VAAPI option in the playback, this issue is not occurred.
This issue is not occurred windows 7 and 8 system.
According to the result, I think that this is VAAPI HW docder issue.
