Description of your issue, suggested solution and other information

The issue applies to all videos on BBC News. It worked fine until a few days/weeks ago.
I read similar topics. Most solutions involved updating the ffmpeg, but I couldn't find a newer version and I believe my ffmpeg is up to date.
