gst-libav should also be sufficient. Also, it *might* be necessary to
install 'gstreamer' to the same profile that 'gst-*' is installed in, to
ensure that the environment variables are automatically set as needed.

I think it's important that plugins with patent-encumbered codecs, or
codecs with code quality issues, should remain *optional*, and not be
installed automatically. It should be possible to install a modern
desktop environment in Guix that does not include these codecs.
What do you think?
