Windows 7 with Google Chrome up to date (Version 65.0.3325.181 (Official Build) (64-bit)) and Adobe Flash Player Plug-In version 188.8.131.52
Video does not display any image (all black), but the sound works fine. It happens in for example Kender Du Typen? - Med flygel og bjælkehytte | TV | DR or in Nye løjer med Emil fra Lønneberg (Dansk tale) - Trailer - YouTube
But most youtube videos work well. I checked in a Flash gaming site and it works fine too. And no video on dr.dk/tv works, althought the sound does.
I have tried deleting browsing data and settings as well as local storing settings by site, but after restarting my browser it still doesn't work.
Can you help me?
Please work through the video troubleshooting guide.
If you're still stuck, please follow the directions in the guide on providing the dxdiag report and additional information about what you tested and saw.
If the problem happens when viewing videos in full-screen, then this is likely a YouTube bug Google has been investigating for more than a year.
