if (descriptors == null)

if (descriptors != null)
{
WMSLoggerFactory.getLogger(CLASS).info(CLASSNAME+".onPMT: Hit cue point PID: 0x"+Integer.toHexString(s.PID));
if (!rtDePacketizerMPEGTS.containsPIDMonitorMap(s.PID))
{
rtDePacketizerMPEGTS.putPIDMonitorMap(s.PID, new MPEGTSMonitorCUE());
}
}
}
}
}
}
```
The code example above as MPEG-TS listener and PID monitor for processing ad markers and inserting the onCUE AMF data event into the stream with the ad marker data.
The are some question i want to know about
- Where do put that code? do have to compile it become jar file?
- Do i still need to setup [Use generic Stream Target API to prepare Apple HLS streams for ad insertion (SCTE-35)](https://www.wowza.com/docs/how-to-use-generic-stream-target-api-to-prepare-apple-hls-streams-for-ad-insertion-scte-35) because our vendor just need to get the SCTE-35 markers.
- Do i need to put that code on all our wowza server?
note : our topology is camera --\> encoder --\> transcoder(ffmpeg) + wowza origin --\> edge server.

- Where do put that code? do have to compile it become jar file?
> Compile into a jar file and put under lib folder of Wowza, then configure the application to load that module, refer the guideline
- Do i still need to setup
> Setup Stream Target to output to UDP (MPEG-TS)
- Do i need to put that code on all our wowza server?
> Only on the server that processing the stream and insert the SCTE-35 marker, then output to MPEG-TS (UDP)

If you want to use the ‘RTPDePacketizerMPEGTSMonitorCUE’, unchanged, then there is a version that is included, so you don’t need to compile the example one. The name is `com.wowza.wms.rtp.depacketizer.RTPDePacketizerMPEGTSMonitorCUE`.
For HLS playback using splice markers, you do need to compile the Stream target code, but if you want to do something else with the data then you will need to use your own code. You would need to enable the depacketizer monitor on each server that is ingesting SCTE-35.
If you would like additional assistance setting up this workflow, you can post in our Hire a Consultant Forum or reach out in a support ticket if you receive error codes. Thanks.

we don’t want to do anything else with the data stream, so for our needs with need to setup and compile the java code an put it on our edge server, isn’t it?
