I'm using Opera GX for a while, but nowadays I experience at some Youtube videos that I can't play them and I get the following error:

In Edge these videos are working fine, but most of the videos works for me at Opera GX also. So I don't really know what is the difference about working and non working ones.

Am I the only one with this issue? Do anyone has any advice, what should I do to resolve it? I don't really want to switch back to Opera from GX.

@leocg Thank you very much, I installed it and it is working fine now. You can close this thread.

@leocg This will be the issue, I have N version. Can I somehow fix it or only with reinstall windows for non N version?

@leocg Honestly I don't remember, how could I check it? But wouldn't cause that one issues at Edge also?

@leocg I compared the results with my Edge browser and found 2 differences:

Video: Edge has H.264 support, but GX does not.
Audio: Edge has AAC suppor, but GX does not.

Edge:

GX:

So maybe we found it, but is there any way to resolve it? Did you get the same results on you GX?

@leocg Sorry, I forgot to mention, but I experience this problem under Windows 10.
