Hi How are attachments (cd cover image, fonts for subtitles, ...) supposed to be stored in nut? As i originally designed things, info packets should have been used. But after changes upon which some fanatically insisted info packets no longer are flexible enough. They are required to be repeated after every header and they can only apply to a single stream. Neither of these limitations was in the original design. So for 10 subtitle streams, we would need a minimum of 30 copies of all fonts. My original design could have stored a version of the font and still kept proper references so that it was known to the demuxer which streams the attachment applied to. -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB I do not agree with what you have to say, but I'll defend to the death your right to say it. -- Voltaire
