Pawel, can you help traige this out? If we can fix this quickly that would be appreciated, as this will hold up the 68 dev release this week.

Actually, if this does not break streaming (e.g. YouTube works) and it is only local video files (rarely used) we can probably go ahead with Dev on this.

Comment 5 by vsu...@chromium.org, May 21 2018 

The description does say YouTube is broken as well; Avinash, can you confirm?

Comment 6 by avkodipelli@chromium.org, May 21 2018 

This has impact on every video which uses H/W decoding, Ex:Youtube, vimeo, local

Comment 7 by avkodipelli@chromium.org, May 21 2018 

FYI, audio is good but video is corrupted for these playbacks.

This issue is specific to Hardware_accelerated video decode. 

Workaround is disabling  "Hardware_accelerated video decode"  flag from about:flags
