As a result of significant code changes after 1.54.00 release and lack of communication with community from my part some deprecated code was removed earlier than expected. Notable examples are: DLNAMediaSubtitle, DLNAMediaInfo, DLNAResource and PMS. Also two public methods were renamed in DLNAMediaInfo: getSubtitlesCodes -> getSubtitleTracksList and getAudioCodes -> getAudioTracksList.
Please make necessary fixes for compilation against git HEAD before next ps3ms release.
Maybe this is sign from heaven to finally read all deprecation warnings and change direct access to instance variables to corresponding getters/setters.
