Yes we can if it has ac3 sound, no, we can't if it > is mp3. Gstreamer with all its plugins is even worse. The same question came up recently on kde-core-devel. (Concerning program-to-mimetype-bindings, which must be highly dynamic due to all those plugin architectures.)
See: "desktop files spec: Plugin based applications and the MimeType key" which links to "desktop files spec: Plugin based applications and the MimeType key" http://lists.freedesktop.org/archives/xdg/2006-September/008556.html and "proposal request: virtual MIME types unknown in time of installation" http://lists.freedesktop.org/archives/xdg/2005-November/007544.html Some mentioned solutions were to let each plugin install .desktop files which contain the supported mimetypes (if that happens, Freevo/kaa could maybe exploit that information), or to have programs like gstreamer ship small binaries which output the supported mimetypes one-per-line. Either way, it is most difficult for Freevo since we have to deal with various audio and video streams in different containers. Thinking about it, I'd say let the backends deal with that diversity, have a proper default player (which hopefully supports all formats) and automatically fall back on another if that player fails for some reason (missing plugin/similar). The more information kaa.metadata is able to extract, the better educated we can make that decision, but that would indeed require some database of supported formats which would best be queryable from the player installations.. -- Ciao, / / .o. /--/ ..o / / ANS ooo
