Well, I think it is, IMHO the code needs some big polishing but it
offers great potentials, it will surely stay around for a while or be
eventually replaced by a feature equivalent (using cairo-gl backend)
gst-plugins-cairo.
Just consider it "lazily" maintained, i.e. be prepared to work
yourself on any bug you may find instead of relying on the maintainers
doing it.

Hope this helps,
