Transcoding definitions have a particular rules for inheritance. Serviio comes with some profiles per-defined but it really is up to the community to create their own configurations for different devices. Generic profile doesn't transcode any local media files, unless they require hardsubs transcoding. An online file is transcoded if there is an OnlineTranscoding or (local) transcoding matching it. Generally, a local file is transcoded if there is a Transcoding or HardSubsTranscoding configuration for it.
General transcoding of files ( Transcoding element), additional transcoding of online files ( OnlineTranscoding element) and transcoding used for burning-in subtitles ( HardSubsTranscoding element). Transcoding configuration is set up per renderer profile in profiles.xml.
