Hi,
We're trying to integrate google dai service in our app. The service would process both live and vod content and eventually provides multi period manifests. We are using the native's AVPlay API to play media content.
Here is what we got so far: When the player plays such streams, it plays only the first period and then it fails/freezes. So my question is:
- Does tizen's AVPlay supprots such streams?
- If it does, then is the player triggers notifications, when it starts playing a new period?
Here is a sample of manifest for a LIVE content generated by dai service:
................................
