1. Rialto is currently enabled on both stable2 and sprint branches, but an old version of it might be used by default. To include the latest version of Rialto in the image, add "rialto_head" to DISTRO_FEATURES in the Yocto build.
  2. Rialto is already integrated into AppService. To use Rialto in the widget, add "rialto" capability in the widget's config.xml file. Once this is set, AppService will include all the needed Rialto resources, and RialtoClient will be able to connect to RialtoServer. 
    <capabilities>
...
<capability name="rialto"/>

</capabilities>
  3. If RialtoClient↔RialtoServer connection is possible, rialto-gstreamer sinks will be added into gst-registry of the gstreamer application when gst_init is called by the client application.
  4. To add content decryption with rialto, change the linked library from libocdm.so to libocdmRialto.so.
