There should not be a gap in text references >1s error

Have you read the FAQ and checked for duplicate open issues?: yes What version of Shaka Player are you using?: 2.5.0 – [JP: assumed to be 2.5.0-beta, which is the latest release as of today] Can you reproduce the issue with our latest release version?: yes Can you reproduce the issue with the latest code from master?: yes Are you using the demo app or your own custom app?: both If custom app, can you reproduce the issue using our demo app?: yes What browser and OS are you using?: mac os & chrome What are the manifest and license server URIs?: https://goo.gl/MDjuDA

What did you do? I tried to play the VOD with enabled subtitles. What did you expect to happen? To have a smooth playback What actually happened? The playback starts fine but if seek to middle, it stops and keeps spamming the console with Assertion failed: There should not be a gap in text references >1s. I checked the MPD and did not see any gaps in the segment template.

This content was produced with shaka-packager. Please note that this content even with subtitles enabled is playable with dashjs and on android with exoplayer. Is this an issue with the packaged content or with shaka player?

Thank you Jakub

I found the cause in Shaka Player, and it should be easy to fix. Thanks for reporting this!

I managed to reproduce using the latest code in master, which is currently equivalent to v2.5.0-beta released a few days ago. I initially missed that subtitles must be enabled for this bug to reproduce.

Full repro steps I came up with:

1. Paste the goo.gl URL into the demo app as a custom asset
2. Click load
3. Get the real URL from the error message in the JS console (since the redirect at goo.gl does not support CORS)
4. Paste the real URL into the custom asset field
5. Click load
6. Wait for the content to play
7. Enable subtitles
8. Seek to the middle (roughly) of the seek range

Also reproduces in v2.4.4, v2.3.10, but not in v2.2.10.
