For best usability, Rhytmbox could be better used by installing gstreamer/gstreamer1 packages from encumbered repository (for example listening radio podcasts over internet) Use pfexec/sudo and IPS pkg(5) command to install, for example:
Other gstreamer , gstreamer1 and other/codecs packages are seen with pkg list command. For example:
..lists available packages at hipster-encumbered publisher (repository)
Use pkg search when searching for packages and see Package Repositories page for adding IPS publishers.
Our small community is always happy to welcome new users and contributors: OpenIndiana is built with oi-userland in the form of a hierarchy of components: aside from the base system illumos, some of these components are developed by the project while others are integrated from open-source projects. Maintaining the different components involves mainly integration: importing, re-branding, applying OpenIndinana-specific fixes.
