What doesn't work on your side?
Audio should work. The problem should be the codec for mp3 or other non-free media formats. See Support mp3 and H264 in video and audio tag
2 extra DLL files from DirectX are needed, or your GFX card/driver is on Chromium's black list. See https://github.com/rogerwang/node-webkit/issues/185
Sometimes the css doesn't display correctly, such as
-webkit-transform:translateZ(-1000px);. Maybe it's the problem with the WebGL.
By default they are running in the same thread.
Lack of libudev.so.0
Maybe node-webkit doesn't work on your computer with the error.
nw: error while loading shared libraries: libudev.so.0: cannot open shared object file: No such file or directory
