DAAP Backend?

Description

On the ArchitecturalOverview page it says a backend translating from DAAP to UPnP AV could be created - is there already such a thing? I personally feel this would be quite an interesting thing to work on. Although I am not really able to write python (which I would have to learn then, have some experience with other languages), I'd like to have a try and work on it.

Are there any good starting points for this like documentation or good example implementations? I have already looked at the existing sources, but there seem to be not that many comments.

Would appreciate any help :)

Well, Python seems quite simple to me, this works fine. Have also found the lolcats example and some API docs, but still I do not understand the concept of BackendItems?, those IDs (e.g. get_by_id and such stuff) and how it is generally meant to work. Could someone please enlighten me?

I've finished so far, the backend works fine. However, there are still some points to work on:

- MIME types: currently, there are only two supported ones: audio/mpeg3 and audio/ogg. its not that easy to do because DAAP does only serve some sort of strange string (of which I don't know how it works) that has to be translated to a MIME type. Still, I have contacted the author of mt-daapd to get at least some information on how DAAP presents the type of a file.

- cleanup: is there a way to know when coherence shuts down? actually, there is the need to logout from the DAAP server

- playlists: according to gupnp-universal-cp, they should work, but totem (GNOME's media player using coherence) does recognize them but can't use them and I don't know any other possibility to test this.

Took a look at it beginning of the week.

No success so far as I do not seem to be able to compile a proper version of the python-daap library.

Any chance you've got a working version of this library for Windows?

Admittedly, I do not know.

Anyway, I must have a look at the backend again next week because there is also a problem with a mt-daapd server distributing a large number of files (~ 15,000) - until now the plugin is working.. and working.. and working with 50% CPU load of both, the mt-daapd and the Coherence process.

When doing this, I'll also test this in my Windows virtual machine. Expect some new information on Tuesday or Wednesday (4th/5th August)

Hi, any feedback from your tests on Windows?

I tested this on jaunty and have few things to say:

- could be nice to use avahi to detect all the DAAP shares on the LAN and export each as a MS - with the rhythmbox share i tried, all the tracks were put at the root level of the MS. could be nice to at least have a by artist/album hierarchy - the ID of the tracks appear to be wrong (when displayed with the inspector)
