Whether we add the new feature via a new, separate mechanism or by extending the existing XML is another matter. I think it should be doable by extending the XML format, even if it means introducing a new sublanguage, analogous to the way VM interaction commands are expressed as a sublanguage within the dvdauthor XML files. > Perhaps a more literal translation of the spu stream with the > ability to implement all control sequence commands in the xml. Yeah. I think this fits in with the overall spirit of DVDAuthor, to provide complete access to capabilities, even if it means doing so at a rather low level. This way, other people can build higher-level tools on top. |
