AirTunes support for the PI is now in master.

Once again thanks for the Demuxer. But the libshairport problem with the ipv6 patch is still present. This is not part of xbmc itself but the patch is deliverd in the xbmc sources.

So the problem occures on machines that have AF_INET6 defined during compilation but IPv6 is not available on runtime. Here are the relavant xbmc.log entries with a little bit extra enabled debug output. It was captured on an OpenELEC build that have the above preconditions. What should be the default at the moment.

Code:

root ~ # cat .xbmc/temp/xbmc.log | grep AIR

07:04 T:1075663376    INFO: AIRPLAY Server: Successfully initialized

07:04 T:1075663376   DEBUG: AIRTUNES: Error setting up server socket on port 36666, try specifying a different port

Have made a minimal invasive patch that fixes the problem. But I am not happy with the libshairport src/socketlib.c code at all.
The patch is a a little bit hard to read because it is a patch for the ipv6 patch.

We are not happy with libshairports code aswell - but thats what we got for supporting airtunes. We want to switch over to libshairplay after frodo and moving all the airplaycode to an addon aswell. Until then i will try to remember to test and add your patch before frodo.

thx

@ribbon10

Patch can be watched here https://github.com/xbmc/xbmc/pull/1573

thx again. (though i didn't test because everything is ipv6 enabled here - at least it didn't break it. But i just try to trust in you that you have verified it. Well once in a time i try to trust Wink

).

kudos to gimli,
great work.

StefanK · 2012-10-30 23:54

I also cannot play sound over airplay (windows-frodo-alpha2 compiled with spotify).
But being a complete github noob I dont know if the four files from gimli can be used by me - not to say how to use them if they do work...

**Memphiz** · 2012-10-31 22:27

Nahh this is definitly not the same issue. Windows uses a different lib. Not really sure if airtunes support for windows was already there in alpha2 tbh. Maybe try a more up to date version.

I just got my rpi and I've been using openelec builds 12220 through 12350 today and I can't get airplay working in any of them. I have airplay enabled in xbmc with no password protection and zeroconf on too, but my iphone doesn't even detect that an airplay device exists and thus doesn't show the airplay icon (other airplay devices on the same network work fine). I tried raspbmc and confirmed that the airplay icon appears on my iphone (but playback of audio doesn't work) and in xbian both the icon and playback of audio works... video didn't).

How can I further debug this with openelec? Step 1 for me is to figure out why the rpi isn't showing as an airplay device on my iphone. Thoughts on what logs to produce to help debug?
