I just ran into this as well.  Repros on current dev, but works ok on beta.

What Android version do you have? What website did you reproduce it on?

Doesn't YouTube use custom controls on Android? pdknsk, is there a reason you used "native" in the summary?

Beta is currently M55 and dev is currently M56, so this is a regression in M56.

This is likely a regression from the controls cutting feature. Though, it would be good to have a page to reproduce the bug on.

This repros on https://developers.google.com/youtube/youtube_player_demo.  I am reproing on Android N.

Taking this since it's semi-blocking something I'm trying to test.

Marking RBS to ensure this gets a merge back to m56.

this is likely same as crbug/672019

Bisect script pointed to this CL as the cause - https://chromium.googlesource.com/chromium/src/+/3347bb8ad251e778ed35c433c0246e0659f2402d

I was using this test page - https://www.buzzfeed.com/mercedessandoval/mini-twice-baked-potatoes

Ensure LayoutMedia notifies MediaControls of panel width

Some pages weren't showing native media controls on Android.  This was easiest to repro when using an iframe to embed youtube content.

LayoutMedia notifies MediaControls of the panel width so MediaControls can decide what controls will fit.  LayoutMedia calculates the size during layout, and only notifies the MediaControls if the size changes.

In the case of the bug, LayoutMedia never notifies MediaControls of the correct size.  The first time layout occurs, there is no child MediaControls.  During subsequent layouts, notifications aren't sent because the size hasn't changed.

The fix is to ensure we send the panel width to MediaControls if the size change or if we haven't yet sent the width.

​> pdknsk, is there a reason you used "native" in the summary?

My comment is obsolete now, but the reason is that the class name of the
bar is yt-native-controls or similar.​

This should now be fixed with the CP back to M56.  Marking as such, please reopen if further work required.

Thanks billorr@ :)

Checked on Pixel XL / NMF26S vs 56.0.2924.23 and Nexus 5 / MOB31H vs 56.0.2924.23 
video controls were fixed, but when you click on the CNN link from Facebook and try to watch video, it will get stuck in spinning mode 
And when I tried to watch video on EuroBD News through Facebook, I see video and control are working fine, but video is cut in half 

please see screenshots and logs -> http://go/chrome-androidlogs1/6/672019 

Reopening until we understand what might be causing this.

Sorry, #c21 is not related to this bug. Please, file a new bug for investigation.
