I’ve looked through the forums trying to find an answer to this, but i haven’t had any luck.
I’ve got a library i’ve just copied over from a windows system, all the files play perfectly under iTunes directly. (most files are aac files).
Some files whilst appearing in the library do not play when streamed by mt-daapd. Interestingly the majority of files that don’t play all appear with the artist “various”.
I’ve rebuilt the database a few times – i’ve checked permissions on all these files.
Any help would be appreciated – this program rocks and I’m going to keep using it regardless!
btw, I have no idea what if any help this will be, but this is the log file of attempting to play one of these files:

Turns out there are two ways to build aac files. One way puts the data in the front of the file, and the metadata at the end. The other way puts the metadata at the front, and the data at the end.
Either way is fine when playing locally, as iTunes can skip to the end of the song, read the metadata about the bitrate, etc, then skip back to the front of the song and start playing.
But if the data is first and the metadata last on a streaming song, iTunes can’t skip to the end to get the metadata it needs to decode the data. I just has to punt.
Formatting aac files so they can be decoded while streaming is called “fast-start streaming”, and you can convert a file to fast-start using mp4creator from the MPEG4IP project.
Command line necessary to do that is discussed here

You know what – I wouldn’t have ever noticed that. In iTunes it actually specifies which version of iTunes created a file in the info page – I’d stared at that info for ages without noticing that some files had that info and others didn’t. I’d forgotten that I’d even used anything else to create some of those files.
I couldn’t seem to get mpeg4ip to work terribly well under Ubuntu (i couldn’t find a package in the 20 minutes i bothered looking). But if you select all the problem files while they’re in a local iTunes library and select “Convert to AAC”… suddenly all is well.
I can’t help but wonder – if iTunes is streaming a file, does it cheat and check the data before it streams it? I’ve never had this problem when using iTunes at both ends.
But for now my problems are solved.
Thanks Ron, you rock. 😳 😳

That’s good info. I’ll remember that if anyone else asks.

Really? iTunes to iTunes it streams okay? Wow… wonder if it is somehow fixing up the data before it streams it. Interesting.

Ha! It happens sometimes. Mostly accidentally. 🙂
