Seems like this is an issue due to Flash version 23.0.0.111 on M53 & M54.

Raising to P0 as this is blocking today's beta release.

Guessing this is due to new flash version.Lopping to Adobe folks.

In the meantime, to get Beta unstuck, would it make sense to rollback Flash and retrigger the build?

Thanks Anthony, we are on the process of rolling back and triggering a new candidate.

CC-ing Joe who is working on crash issues on DRM.

Today, Adobe delivered new Beta builds (23.0.0.126) to Google. Adobe DRM team is aware of that there are crash issues in 23.0.0.111. It looks some of them are fixed in 23.0.0.126, but still it is not perfect.

Confirming that crash is fixed with the previous flash version: 22.0.0.209
53.0.2785.46 (Official Build) (64-bit).

Confirming that, no crash is seen on 53.0.2785.46(flash version: 22.0.0.209) on Windows-7,8,10.

Latest canary with the reverted flash version: 23.0.0.111 is not available due to Issue 634214, hence unable to verify the same on M-54.

DRM Video is not playing in latest canary- 54.0.2819.0 (Official Build) canary (64-bit) with flash version : 23.0.0.126.

Flash is not crashing but videos are not loading.

steele@ can we have the latest update, blocking dev channel release, please get this fixed asap.

There won't be a new build (of Flash Player) in time for the next Dev channel cut.  If the would be advisable to rollback Flash to the LKGR on trunk, so that the Dev cut will be viable.

Dimu@, please roll back to Flash version 22.0.0.209 on trunk to unblock next week Dev.

I reverted the recent 2 flash roll CLs, now trunk Flash version is back to 22.0.0.209.

Thank you Di.

Test team, please make sure that next canary has Flash #22.0.0.209 and it works (no crash and video loads fine).

Verified the fix works fine on current canary build Version 54.0.2820.2 canary (64-bit) - Win7/64 bit.

Adobe Flash Player - Version: 22.0.0.209

Please mark this bug as Fixed as this is working fine as per # 23.
