        Description:
        public abstract class Transcoder : Object
        
        
          The base Transcoder class. Each implementation derives from it and must implement create_source() and get_distance().
          Transcoders are obtained from rygel_media_engine_get_transcoders() and are only expected to support the derived #RygelDataSource types 
            provided by the same media engine.

        Methods:
        
          - public abstract DataSource create_source (MediaItem item, DataSource src) throws ErrorCreates a transcoding source.
             
- public virtual DIDLLiteResource? add_resource (DIDLLiteItemdidl_item, MediaItem item, TranscodeManager manager) throwsErrorDerived classes should implement this function to fill a 
                GUPnPDIDLLiteResource, representing the transcoded content, with parameters specific to the transcoder, such as bitrate or resolution.
                The GUPnPDIDLLiteResource should be instantiated by calling this base class implementation, passing the provided didl_item, item and 
                manager parameters.
             
- public boolcan_handle (stringtarget)Returns whether this trancoder can handle the specified DLNA profile. 
                This is determined by the #RygelTranscodeManager, which checks the suitability of each #RygelTranscoder by calling 
                rygel_transcoder_get_distance() with each #RygelMediaItem, choosing one DLNA profile for each transcoder to handle.
             
- public abstract uintget_distance (MediaItem item)Gets a numeric value that gives an gives an estimate of how hard it 
                would be for this transcoder to trancode @item to the target profile of this transcoder.
