Video.js: Fullscreen player poster and no preload aspect ratio inconsistency

[third774]

Description

When hitting play for the first time, the poster is hidden revealing the video element which does not display with the correct aspect ratio briefly before playback begins. This is much more noticeable on slower connections.

Reduced test case

Steps to reproduce

When the follow criteria are met:

1. Player's dimensions are not fixed pixel values (using viewport in example)
2. preload is set to none
3. poster attribute is set and matches video's aspect ratio

Hit play (in Chrome) and the issue should be visible.

Results

Expected

I expect the video element to display with the same aspect ratio as the poster.

Actual

The video element stretches the poster to a different aspect ratio before correcting itself.

I can reproduce it if I set the connection to slow 3g before hitting play.
I can actually reproduce it without Video.js. Seems like this is a Chrome issue.

Should we keep this issue open to continue tracking?

[gkatsev]

We can. Last I checked there wasn't a bug opened against chrome. Would be good to open a bug against it if one still doesn't exist.

I opened a bug with Chrome for this: https://crbug.com/1154296

[gkatsev]

Going to close this now as we have a crbug. I'll probably circle back here if the issue is ever fixed.

Awesome! Thanks for opening!
