No video playback visible

Installed requirements, got it compiling and linking.
Application starts, can navigate with mouse and cursor keys.
However, there is no video playback visible on the walls.
Still debugging why the video surfaces are displayed black only.

Someone recently tried the application and got video playback visible?

Ok, at least got "active noise" being displayed instead of only a black video surface on the wall:

Ok, needed to change from VA_FOURCC_RGBA to VA_FOURCC_BGRA as shown in PullRequest "#3":
