Note
- When the user leads netflix, plays a video with subtitles and launches the PiP, he will notice that the subs are not displayed in PiP.
Affected versions
- Nightly v102.0a1
- Beta v101.0b5
Affected platforms
- all
Steps to reproduce
- Launch browser.
- Load Netflix, play video with subs.
- Launch PiP
Expected result
- Subtitles are properly displayed in the PiP.
Actual result
- Subtitles aren't being displayed in the PiP.
Regression range
- It is a recent regression between 3rd and 4th of May (nightly v102.0a1). Unfortunately, all the mozregression builds from autoland have failed to play Netflix videos all toghether, were skipped, so a clear regressor could not be determined.
- Mozreg logs:
Tested mozilla-central build: 2022-05-06 (verdict: b)
Tested mozilla-central build: 2022-05-04 (verdict: b)
Tested mozilla-central build: 2022-05-03 (verdict: g)
Bisecting on mozilla-central [ff375ced - 38697602] - none of these builds played netflix
Bisecting on autoland [6783c31c - 38697602] - also these

The dates in comment 0 correspond to a pushlog that at most is a subset of this pushlog, which includes bug 1767516 which also got uplifted to beta, so would explain why this also broke on beta.
I expect Netflix either changed their subtitle code or some films/series produce differently formatted subtitles than others. We should try to make the adapter more tolerant in what it takes in. Niklas, can you take a look?

These are the detailed mozregression logs. All the next builds mozregression spits out (between the 3rd and 4th of May) aren't testable because they won't play Netflix videos.

Bug 1768818 - More robust way to find subtitles on Netflix. r=#pip-reviewers!
Beta/Release Uplift Approval Request
- User impact if declined: Users are unable to see subtitles in the PiP window on Netflix
- Is this code covered by automated tests?: No
- Has the fix been verified in Nightly?: No
- Needs manual test from QE?: Yes
- If yes, steps to reproduce: 1. Navigate to Netflix
- Make sure subtitles are enabled in the original video and make sure
media.videocontrols.picture-in-picture.display-text-tracks.enabled
is set to true - Open a PiP window and confirm the subtitles are visible on the PiP window
- List of other uplifts needed: None
- Risk to taking this patch: Low
- Why is the change risky/not risky? (and alternatives if risky): Not risky because this only affects users watching videos in PiP on Netflix. This is an urgent fix because of the recent release of PiP though.
- String changes made/needed: No
- Is Android affected?: No
