After for example after 30 minutes of watching I want to skip adds, I found on time scale the moment of what is showing as a current playback time plus 5 minutes and click on this point then player start showing instead of next episode after advertising some prior several minutes back episode

What API of archive?

I don't know what you mean about API. Source is ottg.tv from m3u playlist. Progdvb version 7.44.7

But archive is working? You can try change API in IPTV client

ps: Other way is using timeshift in place of archive.
