Sent in email in regards to question https://github.com/shaka-project/shaka-player/issues/5087
What configuration are you using? What is the output of player.getConfiguration()
?
default
What did you do?
Play the manifest url provided in email, in the demo app, select captions -> Svenska There should be some preroll ads, when the program starts, the captions will be out of sync
What did you expect to happen? Captions should be in sync after ad breaks
What actually happened?
Manifest contains #EXT-X-DISCONTINUITY which should signal when sync should be reset, it seems like it's not working properly.
It wasn't an issue before the rewrite to use sequenceMode for HLS, so it works in 3.3.18, the same content also plays fine in other players (hls.js) with no caption sync issues.
@fredrik-telia are you interested on send a PR to fix it? Thanks!
