Hello,

We’re trying to stream MP3’s via HLS, but all it seems to is load and load and load, then the following error is in the log:

```auto
WARN	server	comment	2013-05-09	13:43:21	-	-	-	-	-	0.126	-	-	-	-	-	-	-	127.0.0.1/files/file.mp3	MediaReaderH264.open[2]: java.lang.Exception: QTUtils.parseQTMediaContainer: File is missing 'moov' atom.

```

We’re using the following url:

[HTML]http://[wowza-server]:1935/vod/mp3:/files/file.mp3/playlist.m3u8[/HTML]

Any ideas what could cause this or how to fix it?

Thank you!

Take out the forward slash after the mp3: prefix, and add “_definst_” since the .mp3 file is in a subfolder:

```auto
http://[wowza-server]:1935/vod/_definst_/mp3:files/file.mp3/playlist.m3u8

```

Hi Richard,

That did the trick, now we get:

> Picture data in MP3 file is too large for iOS device playback: limit:256k size:269467

Which is what we’re expecting for this particular file. Thanks so much!
