We have some weird issues serving mp3 files via HLS.

**Firefox** console shows this message “Media resource blob:[http://stage.rosebud-media.de/d82976b7-5554-f142-96fe-07f665759862](http://stage.rosebud-media.de/d82976b7-5554-f142-96fe-07f665759862) could not be decoded.” **Chrome** doesn’t play without any message. **Safari** works fine. Same on Windows and MacOS.

The same file is playing in any browser without any issue when using http download.

Example player can be found here:

[http://stage.rosebud-media.de/jwplayer/bl\_jw\_audio.php](http://stage.rosebud-media.de/jwplayer/bl_jw_audio.php)

The playlist contains some working and not working examples.

For me the issues seems to be clearly related to the Wowza server. Any ideas or suggestions how to solve this?

Thanks,

Oliver

Hi,

Try setting the following property in the Engine Manager:

Path: /Root/Application/HTTPStreamer  
Name: cupertinoPacketizeAllStreamsAsTSVOD  
Type: Boolean  
Value: true

Alternatively, you can edit your [install-dir]/conf/[app-name]/Application.xml and set the HTTPStreamer section to the following (restart the specific Wowza app afterwards)

```auto
<HTTPStreamer>
                       <Properties>
                                <Property>
                                        <Name>cupertinoPacketizeAllStreamsAsTS</Name>
                                        <Value>true</Value>
                                        <Type>Boolean</Type>
                                </Property>
                        </Properties>
</HTTPStreamer>

```

That may make the MP3 file more compatibile with some players.

Regards,

Dear @olt999 and @Paul Shields,

Can i get some sample smil file for audio (MP3 & AAC) only on demand,

coz’ i have some difficulties to play those file.

```auto
<smil>
        <head/>
        <body>
            <switch>
                <audio src="mp3:test.mp3"/>
            </switch>
        </body>
</smil>

```

i only change config from VOD that i’m using to play video from mediacache.

```auto
<smil>
        <head/>
        <body>
            <switch>
                <video src="mp4:mohini2.mp4" system-bitrate="372023" width="416" height="240" />
            </switch>
        </body>
    </smil> 

```

is there anything that i need to add on the audio smil configuration? or is there any configuration i need to update on the vod(media cache) application?

Thanks,

Iyus Dedi Putra
