Ultra low latency wowza player on mobile doesn't work

Hello,

I am using stream target ULL.

I see that on mobile the Wowza player doesn’t work (iOS/Safari and Android/Chrome).

Is this normal ?

Is that possible to have ULL on mobile or not ?

HTML5 player doesn’t support ULL evidently…

Hello @Jeremie PERERA, I see you have submitted a support ticket and will follow the progress.

Here the answer :

For true ULL playback on mobile devices, the GoCoder SDK (App) is required. Some mobile players may work using the Wowza Player but they’ll receive a reduced latency HLS stream instead of the ULL stream. So if the device is compatible, they’ll see a latency time around 8-10 seconds unless they utilize the GoCoder SDK App.

Thanks very much for sharing this with the community.

It is true that with HLS playback, a certain number of “chunks” are required for playback to start and while it can catch up later on in the stream, initial playback will have a bit more latency than true ULL.

BUT, there are things you can do to reduce HLS latency:

Thank you :).

But doing this prevent me to use ULL on computer :slight_smile:
