When I connect 2 clients (use HLS) to a live streaming by WMS, they don’t access to the same location in the stream. Rtmp is fine. How can I fix it? Thanks ---

Because of the way that Wowza chunks streams for HLS there is not a way to synchronize streams between devices. To get closer, you can try encoding with 1 second key frame frequency and set cupertinoChunkDurationTarget to “1000”.

Thanks Richard. After set that, it got better now. But why HLS live stream always start after rtmp ? Can I configure this?
