Youtube problem on Opera

[Dimitri]

Seemingly at random, in Opera YT will give me the message that some video can't be played because I can't play any of the formats, however I clearly play at various times both html5 videos and flash (I can tell by the different interface) and on FFox I can play every YT video.

When I go to the YT page that shows which formats my browser supports there's a ! next to H.264 and MSE & H.264, everything else is good.

Does anyone know why this is happening?

Is this on linux by any chance?

If so, try these directions: https://gist.github.com/lukaszzek/ec04d5c953226c062dac

Its not Linux, I'm on Win XP.

If you go to opera://flags/#mse-h264-support is it set to disabled?

 

[Dimitri]

When I type that into the URL bar it takes me to a menu called "experiments" and there's 128 things I can change but there's no MSE-h264 support option.

However, I just realized that, even tho Opera tells me I have the latest version, I have Opera 36, which is not the latest. So I'll update and get back to you.

Well, turns out that since I'm on win XP this is the latest version I'll be able to use, later versions aren't supported on XP. Don't know whether that makes a difference.

Looked into it a bit more, seems Windows XP doesn't have native support for h264 (which is the MSE-264 thing) hence it not working in Opera.

Firefox may be providing support for it by a plugin I'm not sure.

 

[Dimitri]

I see.

You think this is the reason for this weird behavior of Youtube?

 

[Cromewell]

I suspect yes, but unfortunately I don't have an XP machine I can try it out myself with.

You could try installing a codec pack like K-Lite and see if that helps.

But in all seriousness, you should move off XP.
