Hello,

I have two Wowza systems working in tandem, the first is creating a Stream which runs a Playlist and injects captions via onTextData calls. The resulting stream is pushed to the second Wowza instance which transcodes the stream for HLS delivery.

On the transcoding system, I have enabled the ModuleOnTextDataToCEA608 module and configured it to add the captions to each transcode result by setting closedCaptionLiveEnableTranscoderResults = true.

When the debugging is turned on (closedCaptionLiveLogOnTextDataEvents=true) I can see that the module IS detecting the incoming text data events and is attempting to send them through the transcoded streams:

```auto
2015-07-14	21:13:25	UTC	comment	server	INFO	200	-	ModuleOnTextDataToCEA608#OnTextDataHandler.onCallback[live/_definst_/999]: ccTextBlock:&#9834; PUT YOUR HANDS UP MAKE 'EM TOUCH &#9834;
2015-07-14	21:13:26	UTC	comment	server	INFO	200	-	ModuleOnTextDataToCEA608#OnTextDataHandler.onCallback[live/_definst_/999_160p]: ccTextBlock:&#9834; PUT YOUR HANDS UP MAKE 'EM TOUCH &#9834;
2015-07-14	21:13:26	UTC	comment	server	INFO	200	-	ModuleOnTextDataToCEA608#OnTextDataHandler.onCallback[live/_definst_/999_source]: ccTextBlock:&#9834; PUT YOUR HANDS UP MAKE 'EM TOUCH &#9834;

```

However, when playing back the resulting streams, the captions do not exist. The captions DO exist when I play back the “999” stream, but neither “999\_160p” nor “999\_source” contain any caption data.

Can you provide any advice on how to address this?

The pertinent parts of the Application.xml are below:

```auto
<Module>
  <Name>ModuleOnTextDataToCEA608</Name>
  <Description>ModuleOnTextDataToCEA608</Description>
  <Class>com.wowza.wms.timedtext.live.module.ModuleOnTextDataToCEA608</Class>
</Module>
...
<Properties>
			<Property>
				<Name>closedCaptionLiveCharacterSet</Name>
				<Value>UTF-8</Value>
			</Property>
			<Property>
				<Name>closedCaptionLiveLogOnTextDataEvents</Name>
				<Value>true</Value>
				<Type>Boolean</Type>
			</Property>
			<Property>
				<Name>closedCaptionLiveEnableTranscoderResults</Name>
				<Value>true</Value>
				<Type>Boolean</Type>
			</Property>
</Properties>

```

Thank you
