This causes problems when using Youtube. I'd like to play yt movies on html5, but most of them are coded by webm vp8. Flash plugin disables possibility of play as html5 and forces to play as flash video.</p>
<p dir="auto">Is there any way to have installed and enabled Flash plugin and at the same time play youtube videos as html5 webm vp8?</p>
<p dir="auto">Here is when flash plugins disabled:<br />

And yes, I have Flash Player (15.0.0.152) and it is enabled, and used on YouTube if I choose to use the default player.</p>

<p dir="auto">Flash is being forced in YouTube by you with the PATCH-1164 BrowserJS because YouTube <strong>was</strong> 1. bugging in Opera browser 2. not giving it access to higher resolution videos. Check the bug tracker for the patch, check OTW-9353.</p>

<p dir="auto">HTML5 (VP9) is used, with Flash Player enabled or disabled.</p>
<p dir="auto">Did you try to add an exception for YouTube in opera://settings/contentExceptions#plugins (and set the behaviour to Block)?</p>
<p dir="auto">Which version of Opera do you use? I use 25.0.1606.0 (on Ubuntu) with Flash Player 15.0.0.114 from Chrome beta.</p>

I HAVE html5-player enabled. But most videos are probably coded in vp8, because after opening video, for a second is shown message that codec is missing and player is automaticaly switched to flash version. If these videos would be in vp9, they were opened by html5 player.<br />
When I turn off flash plugin, then the same video is properly played as html5.</p>
