Hi,

I’m testing the latest release. So the new property in HTTPStreamers\>Properties called “cupertinoEnableProgramDateTime” would be nice for us. But, if I do it right, it will not work.

Just got my Information from the release notes which said :

_Added HTTPStreamer/Properties property to control display of program date and time headers in Apple HLS (cupertino) chunklists for live streams. This property must be true and program date and time set in chunk for the header to display:_

_cupertinoEnableProgramDateTime: Boolean property to control if EXT-X-PROGRAM-DATE-TIME headers are added to chunklist (default is false)_

What I’ve done

```auto
                <HTTPStreamer>
                        <Properties>
                                <Property>
                                        <Name>cupertinoEnableProgramDateTime</Name>
                                        <Value>true</Value>
                                </Property>
                              <Property>
                                        <Name>cupertinoUserHTTPHeaders</Name>
                                        <Value>Access-Control-Allow-Origin: *</Value>
                                </Property>
                              <Property>
                                        <Name>mpegdashUserHTTPHeaders</Name>
                                        <Value>Access-Control-Allow-Origin: *</Value>
                                </Property>
                              <Property>
                                        <Name>smoothUserHTTPHeaders</Name>
                                        <Value>Access-Control-Allow-Origin: *</Value>
                                </Property>
                        </Properties>
                </HTTPStreamer>

```

But a

```auto
curl http://10.10.40.22/clemschltest/_definst_/what/a/test.mp4/chunklist_w237516550.m3u8

```

returns

**#EXTM3U**

**#EXT-X-VERSION:3**

**#EXT-X-ALLOW-CACHE:NO**

**#EXT-X-TARGETDURATION:12**

**#EXT-X-MEDIA-SEQUENCE:17**

**#EXTINF:11.745,**

**media\_w237516550\_17.ts**

**#EXTINF:5.823,**

**media\_w237516550\_18.ts**

**#EXTINF:11.713,**

**media\_w237516550\_19.ts**

Are there any further hints? 😕

Thanks a lot!

– Tom

Hi Tom,

There is a preliminary step that you would need to implement in order to view this header in the generated manifest.

You would need to use the following method to intercept the packetizing process:

[https://www.wowza.com/docs/how-to-convert-ontextdata-events-in-a-live-or-vod-stream-to-timed-events-id3-tags-in-an-apple-hls-stream](https://www.wowza.com/docs/how-to-convert-ontextdata-events-in-a-live-or-vod-stream-to-timed-events-id3-tags-in-an-apple-hls-stream)

in any of the calls:

onFillChunkStart

onFillChunkEnd

onFillChunkDataPacket

You can set the program-date and time for that chunk by invoking the chunk.setProgramDateTime(str) method. You would need to do this for each chunk.

Hi michelle\_b,

I meet the same problem, and If I do this by developing a wowza plugin. What does the cupertinoEnableProgramDateTime property mean?
