from the ID3v1 tag solves<br>the problem?<br><br>Lukas<br><br>[1] <a href="https://github.com/taglib/taglib/blob/master/taglib/mpeg/mpegfile.cpp#L159" target="_blank">https://github.com/taglib/taglib/blob/master/taglib/mpeg/mpegfile.cpp#L159</a><br>_______________________________________________<br>taglib-devel mailing list<br><a ymailto="mailto:taglib-devel@kde.org" href="mailto:taglib-devel@kde.org">taglib-devel@kde.org</a><br><a href="https://mail.kde.org/mailman/listinfo/taglib-devel" target="_blank">https://mail.kde.org/mailman/listinfo/taglib-devel</a><br></div></div>
