That message is normal debug output from Awesomium, the Browser embedding technology we're using and can be safely ignored.

What kind of videos are you playing, what resolution are they, what resolution are you running the client at and what hardware are you running the client on?

The view I am playing is not big, it's 720*480 resolution WMV file, it is just windows sample video.
However, the ubuntu linux is installed in VMPlayer. Will it affect the performance?

and when I play the Python Xibo client, the screen shows AVG Renderer, is it possible to configure the renderer as VLC media player ?

Absolutely it will.

You can think of the Xibo Python client as a 3D game. It relies on the hardware acceleration OpenGL gives us - so playing it in VMPlayer will slow things down - as will running on poor graphics hardware or low spec CPU etc.

AVGRenderer is the underlying technology that displays the whole client window. VLC Player is a video player and doesn't have the capabilities that would be required to do the job libavg does. libavg is very efficient - it uses ffmpeg for video decoding.
