Hello all, CC'ing the list.

Good thing is that 10-usb-music-players.fdi is very regular and does not use any weird fdi constructs, thus it's possible to convert it to udev rules and ini files fully automatically (unlike the keymap stuff). Thus we can do a "live migration" from newer hal-infos for a while. I put the current stuff on http://people.ubuntu.com/~pitti/tmp/hal-udev-music-players/ including the generated output from current hal-info trunk. If you want to hack on it, this is how to call it: wget http://people.ubuntu.com/~pitti/tmp/hal-udev-music-players/fdi2rules.py mkdir media-players python fdi2rules.py ~/fdo/hal-info/trunk/fdi/*/*/10-usb-music-players.fdi > 40-usb-music-players.rules Status: * DONE: complete parsing of .fdi * DONE: creation of .ini files * DONE: creation of udev rules * TODO: nicer names for .ini files As you see, the generated 40-usb-music-players.rules is pretty small and just serves to identify a device as a media player. ENV{ID_MEDIA_PLAYER} gives you the file name to look for (which should be somewhere in /usr/share/libmediaplayerid/media-players/<filename>.ini): http://people.ubuntu.com/~pitti/tmp/hal-udev-music-players/40-usb-music-players.rules The .ini files currently have sections 'Device', 'Media', 'Playlist', and 'storage'. This is a pretty comprehensive example of a "normal" USB player: http://people.ubuntu.com/~pitti/tmp/hal-udev-music-players/media-players/781-7432_7433_7434_7435_74c0_74c1_74c2_74c3.ini Different drive type, and special case (no usb vendor/product): http://people.ubuntu.com/~pitti/tmp/hal-udev-music-players/media-players/sony-psp.ini Please have a look and see whether the structure suits you. As I said, I'll strive to generate nicer ini name files, probably by looking up at least the vendor in usb.ids. A big question now is finding a place where this data should live. As a fallback we could dump it into udev-extras, but since we also have stuff like http://bugzilla.gnome.org/show_bug.cgi?id=551403, and perhaps some code to infer a proper icon from a device, it would perhaps make sense to create a libmediaplayerid project and add this and future code there. I wouldn't like to be the primary developer on this, since this should be driven by the Rhythmbox/Banshee/Amarok/GStreamer/etc. developers, but I'm fine to continue to maintain the actual player DB, from bug reports (just as I'm doing with hal-info nowadays). Thanks in advance for any ideas, Martin -- Martin Pitt | http://www.piware.de Ubuntu Developer (www.ubuntu.com) | Debian Developer (www.debian.org)
