faad_decode:387 error reading stream header

[GoogleCodeExporter]

Just tried to play a m4a album and squeezelite exploded with the `error reading 
stream` message. None of the tracks played (but they work in other places: vlc, 
other hardware squeezeboxes).

I've tried 1.3, upgraded to 1.5 and then built from trunk. All showed the same 
error. Other music plays fine.

I'm happy to give you as much header information as I can about this file but I 
obviously can't upload it for copyright reasons. This was ripped *years* ago so 
again, no idea how I did this, let alone a way to reproduce it. Here's a avconv 
dump to get you started :)

Can you edit the file to only include the first second of audio and upload it?  
Can't do anything with this data without the file I'm afraid.

Also can you enable debugging and post what the output is?

Attached is:

 - a 5 second excerpt that triggers the same broken response
 - The `-l all=sdebug` log of that trying to play.

I've tested the file again in other players and they seem to cope with it just 
fine. Warning, it starts quiet and gets quiet loud but that's Coldplay's fault, 
not mine :)

This will play on squeezelite if you disable native playback for mp4 and rely 
on faad to decode on the server.  However, I don't believe it will play on 
hardware players with native mp4/aac decode either - Touch or Radio.

The problem is that the metadata necessary to decode the audio comes after the 
audio data.  When transcoding on the server or reading the file from a local 
application it is possible to skip to the end of the file to find it.  However 
when streaming to a player, the player doesn't get this information.

That makes sense, thank you. It is working on our Radio so I had a quick look 
in the webmin while it was playing and say this:

 Bitrate: 335kbps CBR (Converted to 705kbps FLAC) 

So I assume this is the server transcoding it. No idea why.

HODOR HODOR!

It was synced with two other players so it was proxied. After unsyncing it 
fails very much as it did locally with the squeezelite! So that's good. Crappy 
files are the problem.

Sorry for making you trawl through a problem that isn't really yours. I'll see 
if I can badger this album into working. Thanks again.
