Hey James,
You might want to have a look at bug
709723 as well.
I haven't thought about it in a bit, but I recall that some slight
refactoring of how rygel-relational-_expression_.vala does its thing
would be useful for supporting the musicTrack/musicAlbum/etc.
There's a patch I attached to the bug
demonstrating a pattern that should allow for the UPnP
class-specific properties to be added cleanly. I just didn't have
time to follow through on it, unfortunately. (and the last thing
Jens needs are more patches from me... ;^J)
To answer your question about dev tools: I've been using Geany for
my Rygel development. It has limited symbolic capabilities. But it
can invoke valac just fine, walk through compilers errors, etc.
pretty well.
hth,

Hi
A couple of questions here:
1. As I mentioned last month, I'm developing my own external
plug-in (DBus server) for rygel. For small (and static) music
collections it's working OK on most of the UPnP clients I've
tested it with, apart from one. This is a Roberts Stream 63i
radio (so an embedded client), and the problem is that music
tracks are being displayed in alphabetical order, not track
sequence. It only happens with this client, and the client works
fine with other UPnP servers (minimserver, serviio, minidnla,
mediatomb).
I'm using the most recent release (including the fix to bug
720672) so rygel should be passing through the sort sequence from
the external plugin unchanged. My DBus server is passing the
items through in track sequence - and if I use the UPnPlay Android
app with the "let server decide sequence" option the tracks appear
in the correct order.
My hypothesis is that there's code in the Stream 63i that checks
the upnp class of the container and sorts by name (or requests the
items sorted by name) if the container isn't
object.container.album.musicAlbum. I've used uPnP-inspector to
browse the same album shared from rygel and minidnla;
uPnP-inspector displays the tracks in the correct order and the
only meaningful difference between the two servers is the upnp
class of the container (with rygel it's just object.container,
with minidnla it's object.container.album.musicAlbum).
I've seen via
http://comments.gmane.org/gmane.comp.gnome.apps.rygel/432 that
there has been discussion about extending the MediaServer2 spec to
allow containers to be identified as albums - is anyone still
looking at this or has it been set aside for lack of time?
Presumably all that needs to be done is to retrieve the new DBus
property (if it is set) and then amend the upnp_class of the
container object appropriately.
I might have a try at incorporating this myself... which leads me
onto my second question
2. I can code, but I've not worked on a multi-sourcefile project
like rygel for 20+ years (the last IDE I used was Visual C++ 1.0).
I know my way around Linux but have never done serious software
building on it. And I have no experience with vala of course. So
- (a) are the build instructions on the gnome wiki for rygel still
up to date?, and (b) can you recommend an IDE? What development
tools work best for you?
Thanks
James
