Wait for the end of the first ad, at the end (~30s) it says "hers.com" but the ".com" audio is often cut off.
What did you expect to happen?
The audio shouldn't be cut off.
What actually happened?
The player is reporting a gap even though there is no gap if you inspect the media:
Jumping forward 0.3113419999999998 seconds because of gap starting at 29.994666 and ending at 30.03
The audio rendition is actually 30.08s and the video is 30.03s.
We were wondering if shaka is getting an incorrect duration for the audio, thinks there is a gap, and then mistakenly jumps ahead. Some decoders may discard what they think are priming samples and shorten the audio. Our audio files do not have priming samples.
Are you planning to send a PR to fix it?
No
