Gstreamer was not installed by reporter.
Can an administrator close this bug as INVALID?
No problem with that. My confusion came from gentoo maintainers which doesn't put gstreamer are hard dependency for wine. Other source of confusion is when gentoo maintainers use gstreamer flag is rather to install gstreamer backend than using it as a multimedia framework.
