Transcoder
Object Hierarchy:
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
Error
Creates a transcoding source.
- public virtual
DIDLLiteResource
? add_resource (DIDLLiteItem
didl_item, MediaItem item, TranscodeManager manager) throws Error
Derived 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
bool
can_handle (string
target)
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
uint
get_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.

bool
mime_type_is_a (string
mime_type1, string
mime_type2)
