Details

Was watching a 30 minutes video. 15 minutes into it an ad got displayed for 15s. When normal program resumed, A/V sync was off by about 3s.

I've reproduced it twice ; unfortunately, getting the ad mid-stream appears random.

I believe this is something Maja reported alread; so likely a duplicate of another bug

I haven't seen it myself, but Syd described something similar while working on EME tests in a hotel room with terrible wifi.

I was testing our automated video tests. Basically, I saw three behaviors when there was a network stall:

- The video started where it left off.
- The video started, but audio was not in sync.
- The audio kept playing, and the video played real fast until it caught up.

I don't have a good sample as to how often each event happened.
