Navigate to https://awstest.wevideo.com/static/movieeditor/test/video.html on a convertible (laptop/tablet) chromebook 2. Press play What is the expected behavior? You should see two videos playing What went wrong? On convertible chromebooks, only one video is playing. Perhaps related to https://bugs.chromium.org/p/chromium/issues/detail?id=701060 Seems to be working without any issue on non convertible chromebooks, mac os x, and windows chrome. Is it a problem with Flash or HTML5? HTML5 Chrome version: 63.0.3239.132 Channel: stable OS Version: 63.0.3239.116 (Official Build) (32-bit) We believe this to be isolated to a specific chipset on convertible chromebooks. Rockchip chipset with a Mali-T760 gpu Reported devices with the issue include Asus Chromebook Flip c100 and CTL Chromebook Model J4+

Disabling chrome://flags/#disable-accelerated-video-decode appears to have fixed the problem on my ASUS Flip C100PA

This fixed my Samsung Chromebook Plus.

Will disabling accelerated video decode have a negative impact on other applications? We are experiencing this problem on ctl J4+ as well. It is affecting our students when they are using WeVideo.com and trying to layer text over background images.

Disabling the accelerated video decode fixed this problem for my chromebook. I have not seen any negative consequences while using various web based video, graphics, html, flash, web browsing, and gsuite services - as of yet.

At most you'll see increased battery drain, if that's not a problem for you then that's a reasonable workaround.

Could reproduce the issue with build R63-10032.79.0 on Minnie, investigating...

This is fixed on R64-10176.65.0. Performing a bisect.

Found that the issue was fixed between 10176.14.0 and 10176.15.0, meaning the fix has landed in Chrome between 64.0.3282.24 and 64.0.3282.31. Looking from there.

This issue is fixed by the following CL: https://chromium-review.googlesource.com/c/chromium/src/+/821151 It is already in M64, but a merge to M63 is also necessary - requesting approval for merging to M63.

M64 is already shipping to stable, I don't think they're taking 63 merges anymore.

Yeah, looks like I am kind of alone on the Merge-Request-63 tag. :) Closing as fixed, since this is fixed in 64 which should ship soon.

Some of our chrome books will still not display the preview screen/canvas. We shut down and restarted and we also disabled accelerated video decode. We are running version 63 and cannot update to 64, which might be a fix, because our state testing is being done now and they only support 60 to 63. Also, some that are running 63 work while others don't. |
