Hello, I am recording an MP4 with AMF metadata in Wowza from my incoming RTMP stream. I know wowza can restream this MP4 as an HLS stream, but how do I get the metadata out of this file for conversion to ID3?

Do I just use the standard **IHTTPStreamerCupertinoLivePacketizerDataHandler2** and get the data in the **onFillChunkDataPacket** method?

I wound up extending **IHTTPStreamerCupertinoVODActionNotify**.

I started from the example here:

> <https://github.com/WowzaMediaSystems/wse-plugin-cupertinoliveattachpicture/blob/main/src/com/wowza/wms/plugin/CupertinoVODAttachPicture.java>

And then wound up including an override for this method to do the injection of metadata as ID3 tags:

```
public void onFillChunkDataPacket(IHTTPStreamerCupertinoIndex index, IHTTPStreamerCupertinoIndexItem indexItem,
				LiveStreamPacketizerCupertinoChunk chunk, boolean arg3, AMFPacket packet, ID3Frames id3Frames) { 
...
}
```
