Dear All,

i’m currently trying to publish my app on the apple store.

So i use the mediastreamvalidator tools from apple to check if my stream if my m3u8 playlist is correct.

The tools give me some warnings :

Playlist Syntax:

```auto
Warning: (0:-12274) PROGRAM-ID has been deprecated and is no longer a valid attribute for #EXT-X-STREAM-INF
	--> #EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=4245000,RESOLUTION=1920x1080

```

Is there any problem?

Best regards

Richard

hi Richard,

From what I know, Warning lines in Apple Validator are not critical for App store acceptance. I can’t explain why PROGRAM-ID is reported deprecated, but it is still part of the Wowza HLS playlist and is not a problem.
