Netflix & Amazon Prime Video, at fullscreen, jump between various crop/zoom levels

Reported by eofferm...@gmail.com, Jan 30 2018

Issue description

UserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36

Example URL:
https://www.amazon.com/Suits-Pilot/dp/B005544V6A

Steps to reproduce the problem:
1. Play video
2. Watch as video switches to peculiar crops

What is the expected behavior?
Video to play at a consistent aspect ratio and uncropped.

What went wrong?
In the last few days (likely beginning with the update to 64.0.3282) the video rectangle will change periodically during playback. It seems to coincide with scene changes - I don't *think* I've seen it do it mid-cut, though because of how dramatic the crops can be, it's hard to tell.

Sometimes it will be letterboxed at 1.85:1 and bounce to fullscreen 16:9 and then back. At other times, it will suddenly punch in, grabbing a center crop, then pop back to normal framing. It happens frequently or infrequently, but seems to be repeatable at the same locations in a stream.

Playing the same stream on Safari and Chrome version 63.0.3239.132 (on Windows) and the videos play as expected on both.

Did this work before? Yes 63.0.3239

Is it a problem with Flash or HTML5? HTML5

Does this work in other browsers? Yes

Comment 3 by ericde@google.com, Jan 30 2018

@eoffermann : I tried to repro this on my mac using M64 stable and couldn't repro it. Fullscreen stayed same letterboxed aspect ratio, and outside of changing resolution (increasing to HD), playback was unchanged for 10min I watched. I'll try different titles, but when you saw this issue how long did it take to repro and does it do so consistently?
On that particular stream it took place during the opening scenes which is why I singled out that particular one. On other videos it takes place at other places throughout the stream and may not show up for some time.

When it occurs, it has been very consistent. Leaving the page and returning, even quitting Chrome and relaunching, it would recur consistently in what would appear to be the same moments in the stream.

I’ll test with the developer console up later and see if there’s anything more illuminating. I’ll also try doing a fresh install of Chrome at that time and report back.

I don’t know for certain that it’s not doing it on other sites - but I’m fairly certain I’ve watched Hulu on that machine, with that version of Chrome, and haven’t seen the problem. Same goes for watching something from my Plex server. Not sure if that’s helpful or not.
After reinstalling, the problem hasn't recurred. Considering that "playing video on Netflix and Amazon Prime" are not edge-case behaviors, I'd expect to see a flood of similar reports soon if this represents a widespread bug. Otherwise, can probably be dismissed as a corrupted file somewhere.
Unable to reproduce the issue on chrome version 64.0.3282.119 using Mac 10.13.1 with steps mentioned below:
1) Launched chrome reported version and navigated to URL https://www.amazon.com/Suits-Pilot/dp/B005544V6A
2) Unable to play the video (Please find the attached screenshot 807176.png)

We tried playing another video from Amazon prime videos, unable to reproduce the issue, we tried playing for around 10 min.

@Reporter:
Please find the attached screencast for your reference and let us know if we missed anything in reproducing the issue. Try to test this issue by creating new profile with no extensions and apps in it and let us know if the issue still persists.

Thanks!

Are you watching with captions? If so, is it possible that the changes happen when the captions disappear? This could be triggered by low power fullscreen.

Either way, is there a chance you could share a video?
Not watching with captions.

It's now been about a week since it last happened - it was very persistent
until it wasn't.

I'd have to check that machine to see if Chrome updated on it - I know
there was a minor release Feb 1 that seems to have a bit of fullscreen code
fixes in it. This problem wasn't considered in the release notes, but may
have addressed an underlying cause accidentally.

Either way, I can no longer reproduce it either - so I'd consider the
problem resolved unless others report issues as well.

Status: WontFix (was: Unconfirmed)
As per the comment#9 from the reporter, as the issue is no longer reproducible, hence closing this and marking it as won't fix.
Removing Needs-Bisect label as the issue is not reproducible from reporters end.

@Reporter:
Feel free to raise a new issue if you reproduce the issue again.

Thanks!
