I am a little unclear as to the current state of DAAP support in XBMC.

I currently run XBMC installed via XBMC's stable PPA on Ubuntu 10.10 i686, there is no SVN revision in the sys info, it only says Built on Mar 9 2011 (Git:Unknown).

I am running the mt-daapd DAAP server, availalbe in the Ubuntu 10.10 repos. I am able to add it as a source by selecting: Add Source > Add network location and choosing iiTunes music share (DAAP) as the Protocol.

I can play files when not in library mode, but in library mode I get a playback error. To reproduce, simply add a DAAP server as a source, scan it to the library, browse the library and try to play a song. I only have MP3s, so I don't know if it happens to other codecs as well.

My debug log file from this is here if you are interested: http://www.prupert.co.uk/scripts/xbmc.log careful, it is 16,000 lines long and 1.5MB in size, though here is a snippet of the log when it fails to play:

It looks like there is no player capable of playing the DAAP protocol in library mode.

I was all set to post a bug report, when I did a few forum searches first.

I found these posts:

http://forum.xbmc.org/showthread.php?tid...light=daap
http://forum.xbmc.org/showthread.php?tid...light=daap
http://forum.xbmc.org/showthread.php?tid...light=daap

http://forum.xbmc.org/showthread.php?tid...light=daap

Showing this problem is impacting all platforms and it has got no response from the devs, though admitedly most of these error reports weren't even following the basic guidelines for error reporting.

I then came across this post:

http://forum.xbmc.org/showthread.php?tid...light=daap

Which seems to indicate that as far as the devs are concerned, DAAP is no longer supported.

If this is the case, why then is it still listed as a Network Location and why is there no mention on the DAAP XBMC wiki page (http://wiki.xbmc.org/index.php?title=ITunes_(DAAP)) that support has been fazed out?

I know it is great to continue to add support for new features and platforms, but if this means phasing out other features, it is important to document that as well.

It'd be great to get a final viewpoint on this, because if DAAP isn't supported, I'd love to know what people do to share one common music library across multiple devices with one common playcount record (as XBMC's shared SQL solution doesn't yet seem to support playcount and there is no way marry this solution to syncing with a portable device like an Android phone or iPod).

I suspect (and you're probably in a better position than me to find out) that the reason is because you lose the session-id - i.e. whatever is in the library (check the files/path tables) is missing information in order to actually find the song to play it.

If you can sort that out, then we'd be happy to have it fixed. Effectively you require a stable URL so that given the URL you can play the song.

Cheers,
Jonathan

Hi

Thanks very much for the reply.

I'll have a look through the database and see what I can find. I am not that familiar with mysql, but I am sure I can find something on the net to let me have a basic look at the table.

I'll let you know what I find.

Cheers

So, been doing some digging.

The only difference between what I can see in the library when it doesn't play and what XBMC access direct from the daap server when it does play is the session-id changes.

Here is the log when it succeeds by manually browsing the daap server:

Weirdly here, I chose the same song, but the file name is totally different, so I am thinking there is also an error in the library import as well. Are you able to tell me what the "musicdb://4/" refers to, is the 4 the 4th path entry in the music db? If it is, then it is using the wrong path, it should be 2. Also, I notice in the SQL db, in the path table, one of the paths (the one that works when playing in non-library mode) doesn't have a strHash...., is this important?

So, it is recording a session-id, but maybe it is getting the path wrong?

soulchar · 2011-04-10, 09:23

I've taken a quick look in the DB too.
The entries seem to be correct and the Web Interfaces are able to display and play from the library as it should be.
The 'musicdb://...' call seems to resolve a wrong path.

That is also the conclusion I have come to (though interesting that the web interface gets it right, i did't know that).

Unfortunately, I can't as yet decipher the music db entry that is called when trying to play from the library via the GUI.

Looks like we are on the right path to getting this fixed though.

Devs, how can we progress this and help to get it fixed?

prupert · 2011-04-14, 10:27

This is just a little gentle BUMP.

How can we progress this futher devs to help get this fixed, since it seems to be a problem with the path location entered in the library when scanning DAAP shares....?

Do we need to submit this to a spearate bugzilla / trac site?

I'd love to submit a fix myself if I could, but my coding skills stop at basic VBA in Excel, Syntax in SPSS and Bash in Linux, so I can't help much on that front.

soulchar · 2011-04-14, 17:53

This bug is tracked for 2 years now:
http://trac.xbmc.org/ticket/6540

I think there not enough people who are using a daap server, so it is not important enough Sad

prupert · 2011-04-14, 21:43

Ahh, bugger, that's a shame. Still can't get why people don't use DAAP more, since it seems like the best solution for multi-PC set-ups.

~~Robotica~~ · 2011-04-15, 13:00

Maybe you should update the ticket with your findings and some devs might be triggered to fix your problems.

prupert · 2011-04-15, 21:47

Maybe I am being really dumb, but I can't see anyway to register and thus login to post comments to the bug.......
