Bij mij is het probleem opgelost door in Chrome naar deze pagina te gaan
en de versnelling dus aan te zetten.
“I found a solution. I had already tried installing the codec pack, but there was no difference. I went into chromes setting here: chrome://flags/#disable-accelerated-video-decode, and disabled it, enabling acceleration. Now everything looks great. And videos seem to be running clear. This option is different from the one I found in chromes settings disabling 3d acceleration.”
Of zie hier.
