I can't get videos to play in Chrome. Every other time, I've had to turn off Hardware Acceleration then turn it back on as described in this answer (Chrome youtube doesn't play/Twitch plays with no sound), but now that doesn't even work! I even tried incognito mode. Videos play in VideoLAN and IE.
Here are some examples of videos that won't play: https://vimeo.com/channels/staffpicks/162334918, https://www.facebook.com/ABC7MorningShow/videos/vb.603158273027819/1198044330205874/
I tried to disable this setting, chrome://flags/#disable-accelerated-video-decode, but it still won't work.
I tried to disable Pepper Flash, chrome://plugins/, but it still won't work.
Version 50.0.2661.75 m, Google Chrome is up to date. They release a new version, Version 50.0.2661.87 m, but it's still broken.
