Description

GUPnPDLNAAudioInformation holds all audio metadatas important for matching profiles. Note that it does not mean all data should be provided for every audio file as in some cases it does not make sense (e.g. WMA version does not make sense for MPEG audio files).

For metadata attributes that do not exist in current audio file an unset value should be returned. For metadata attributes that do exist a set value with proper underlying value should be returned. In case metadata extractor has completely no clue how to extract some metadata attribute at all, an unsupported value should be returned. Note that unsupported values should be a temporary mean before fixing the multimedia framework to be able to extract such attribute.

Note that gupnp_dlna_audio_information_get_mime() should always return a set value. Otherwise it is highly probably that the file will not match against any DLNA profile.
