Can't find anything related to this, so I may asked:
Current vlcs (e.g. 2.1.3) play fine with h264-Video, but at the end of the video or when pressing the stop button vlc vanish into nothing. Playing the same videos without vaapi enabled (hw acceleration disabled at all) don't make vlc disappear pressing the stop button or reaching the end of the video.
I watch this on archlinux on a pc with intel HD 2000 Graphics.
Has someone else noticed this? Someone else with intel HD Graphics using vaapi without these observations?
