[Tizen 2020] Problem with stream start for CSAI streams

Open mkochman opened this issue 9 months ago • 0 comments

Hi, I get quite strange behaviour only on Tizen 2020 and CSAI streams with ads, the stream doesn't start, it gets stuck in seeking.

Logic flow looks like that:

  • Get main stream info from API
  • Get ads info from API
  • Add main video element and load
  • If ads then stop main video, remove video element and start ad break
  • Add ad video element, set ad source etc.
  • Run ads...
  • End ad break
  • Remove ad video element
  • Add main video element
  • Set main stream and reload

Only Tizen 2020 have this issue, tried with Tizen 2018/2019, Webos 2018-2020, etc. and it works perfectly there.

Here are some events that we get, it's quite strange that it gets duration change and also emptied 🤔

We also have shaka player integration and it works ok there.
