I have done everything suggested in the last two years to try and get videos working again. I hjave NO extensions, the videos do not work in safe mode, I've downloaded and installed all of the recommended libraries. And please stop referring me to youtube's video checker, as it says everything is perfect, but still nothing works.

Any media related messages in the Web Console or in the Browser Console (show content messages) ?

I assume you have the latest FFmpeg/libavcodec packages installed ?
