Zattoo HLS5 live stream: Large audio sync error

[sunsettrack4]

Good day,

I'm working on a solution to watch Zattoo live streams via IPTV Simple Client. In Kodi 19, the support for the inputstream.adaptive addon has been added for IPTV Simple PVR. Unfortunately, the most streams do not start with audio properly. After a few seconds of video playback without audio, the screen gets black, then the stream starts correctly.

The .m3u8 file provides separated video and audio segments.
Example: https://streams.wilmaa.com/m3u8/get?channelId=pro7_ch_hd&profile=8

I hope that a solution can be found - if you need more information about the .m3u8 files, just let me know :)

Can you try pausing and unpausing briefly at the start? We have seen a similar issue for some streams, and pausing/unpausing seems to help.

You could also try the new upcoming v2.4.3 release from #387
