I want to construct a streaming backend for the following usage: - Android client ‘A’ send audio stream ‘A@’ to backend - Android client ‘B’ playback the stream ‘A@’ - There is no inverse situation. ‘A’ just send stream, and ‘B’ just playback the stream. - One user holds ‘A’, ‘B’ device and multiple users can exist simultaneously. Under the above circumstance, i’m testing [gocoder-sdk-sample-app](https://github.com/WowzaMediaSystems/gocoder-sdk-samples-android) using Wowza Streaming Engine, and seems like working. - Device ‘A’ sends stream ‘A@’ and device ‘B’ playback ‘A@’ by accessing ‘http://{IP\_ADDRESS}/live/myStream/playlist.m3u8’. What I wonder is, does my approach is appropriate for situation i mentioned above? I think it’s a bit vague because for supporting multiple user simultaneously, each stream must be unique and then i must use database or ‘non-collision’ hash function or something. Also, is it possible to run m3u8 files natively using some built-in feature of the SDK instead a web browser? I’m new to Wowza, so any advice would be appreciated. ---
