<![CDATA[Opera 45: Problems with Video Playback]]>Hello everyone,

I have the following problem with Opera (Version 45):
When I try to watch (some) Videos on Youtube, I get the following error message:
"Your browser doesn't know any avaliable video formats"
(may not be 100% accurate, I have to translate it from german.
Strangely, this doesn't happen to all videos, only to some. After I refresh the page with the video that wasn't working, it sometimes starts to work..

I have the same problem on Twitch (Error Message: "No supported video backend avaliable; Flash is not installed).
There it happens to all streams however.
I checked the Opera settings, flash is enabled there.

The error occured yesterday, I switched to Opera two days ago.
I have my 2nd PC running side-by-side to my main one, also running Opera in the same Version, installed on the same day.
All Settings are exactly the same.
There I dont have any problems like that.

I already tried re-installing Opera, unfortunately it didn't work..

Thanks in advance!

This is weird however, because the error says "Flash is not installed".

In opera:// gpu it says, that Video Decode is Hardware accelerated.
Here is a screenshot of the page, in case it is needed:

When having just two tabs open (twitch + opera://media-internals/) it doesn't show any players

Does Twitch use Flash? If so then nothing will be shown on media-internals.

Does opera://gpu says that video decode uses hardware acceleration?

The Youtube-problem seems like is has fixed itself, I am only experiencing issues with Twitch at the moment.

Didn't work either.

Something else, that might be worth mentioning, is that I am using Windows Server 2016 as my OS.
I doubt that it makes a difference however, since other browsers are working fine..

OSync didn't help too.

It might be 3rd party cookies or some other setting - not sure. But reuters.tv always works and some of their other links in stories occasionally work. I always have flash disabled in the chromium based browsers, and not installed in the others. There are very few sites that still suck as far as needing flash - but they are evolving.

Using OSync also helps for some things.

If a clean profile doesn't fix the problem, then reinstall Opera and check what happens, maybe something broken.

Was looking in the wrong directory - there are so many of them nowadays!

Unfortunately a private window or creating a new profile didn't help.
I also tried copying the profile from the working PC, no success either.

From what I know, Twitch is using HTML5 too.
When I manually install Flash it works, but I am asuming I dont need to manually install Flash on my PC?
It works on my other PC and in other browsers, without having Flash installed.

I renamed the old profile folder to *.OLD hoping to keep the original and all it's setting files. The newer version of Opera seems to have a new approach and rather than just recreating a new unpopulated profile folder it wiped the old one out. So I have now lost all my bookmarks, settings etc. 😞

So if you create a new clean profile be sure to take a backup of the old one first.

Now I just have to recreate my original settings etc!

Opera AdBlocker and extensions enabled.

You may try with a Private window Ctrl+Shift+N or a clean profile or download this as a clean profile.

Anyone any idea why none of these Reuters videos will play?

http://www.reuters.com/video

Win 8, Opera 45.0.2552.881, Flash 27.0.0.171

Flash is installed and working OK on other sites, HTML 5 video working OK on other sites. AdBlocker On/Off, makes no difference.

Play fine even in IE v10!
