@avl I have the same issue. It started after updating opera and my mac on the same day.
It's happening on sites like
IMDB where the video starts then freezes and then you see : This video file cannot be played.
(Error Code: 224002) .
Tumblr where the video disappears as soon as I try to play it.
On instagram the video starts playing then stops.
It's also happening on various streaming websites, such as Vidtodo where the video does not play at all and it says The media playback was aborted due to a corruption problem or because the media used features your browser did not support.
Would love some help! thanks. The videos are playing fine on Safari, but I usually prefer Opera and would like to keep using it.
