Hi, gstreamer-devel:
Sorry guy, Actually I have no experiences on running gstreamer on
windows. So you should dig it yourself or ask somebody else. On linux, seems
there is no need to set any environment variables. I compiled gstreamer and
plugins on linux and install, that's all. Everything works fine.
