Problem with Wowza nDVR UTC playlist request api

Wowza Streaming Engine
1

WSE UTC playlist request api returns playlist of duration lesser than requested.

For Example: - http://host/app/stream/playlist.m3u8?DVR&wowzadvrplayliststart=20190517115100&wowzadvrplaylistduration=3600000

The above url requests a playlist of an hour, but WSE would fetch me video of around 50 minutes.

This is the tutorial used to use the api: https://www.wowza.com/docs/how-to-use-wowza-ndvr-playlist-request-api

I run WSE 4.7.7, on ubuntu 16.04 and Java 1.8

Is there a problem with the question here?
Does this not reach the right people?

I have been facing issues with this since long.

Hello @Anurag Saini, you have my apology for missing this in the forums- I was out of the country when you posted this in May. I do see you had submitted a ticket for this issue twice and in checking the tickets, the engineers had tried sharing potential solutions with you for 6 days and it says they got no response from you- they tried to directly email you as well. Is it possible that all their emails went into a spam box and you missed them?

Ticket #322639

and

Ticket # 322362

I can try and share some of what they suggested here, but it’s quite long and several engineers had posted. I would also suggest you search your emails for those tickets.

@Anurag Saini

We have some example code that discusses this here:
https://www.wowza.com/docs/how-to-use-wowza-ndvr-recording-api

You would need to create the custom code as we do not have a prebuilt custom module for the specific workflow that you require.

Please do keep in mind that one drawback to this workflow would be that when there is a rollover from one 24 hour period (day) to the next, it would be hard to configure the API call to start in one dvr store and end in another.

From your tickets:

I also see that you do have a custom property configured to accommodate the 30 days of recording storage.
This type of settings can lead to performance issues with DVR. The maximum limit we recommend is 30 hours.
