Does it run when you click on "Run all plugins this time"?

I can't repro on Samus M55/8783.0.0/23.0.0.162, but it looks like you are prevented by corp policy from automatically playing Flash content.

Notice this site has a working html5 fallback, so if Flash is properly disabled it still plays the video.

issue no reproduce on 8743.18.0/54.0.2840.15. the video from above two link play fine without issue

I am using non-corp account to login and everything is fine.

Thank you for spending time to repro the issue and look into this bug.

I can still reproduce the issue (ie videos still dont play) even if I allow plugins from Omnibox or right click to play the video.

Can repro issue while connected to Google or my own network
Plugin setting : Let me choose when to run plugin content.

However, I can play video if I disable flash from chrome://plugins
Given that we have a workaround, I can try to propose this solution to the user.

I just tested it on my beta channel samus

http://www.cnn.com/help/cnngo-troubleshooting.html doesn't work initially. However, after I enabled 3rd party cookies and reset my DRM instructions, it is working

Wrt brainpop - original bug - it is working in both Flash and non flash situations, as intended.

Not sure what the issue might have been on M53, sounds like we are having trouble reproing, but we've fixed the click to run issue that's present in M54+ (https://bugs.chromium.org/p/chromium/issues/detail?id=641028).

jainabhishek - can you update Chrome (from chrome://chrome) and see if you can still repro?

Just verified, I was able to play flash video without any issues.
