I am getting this error with Vivaldi: Adobe Flash Player is blocked
-

@cejno It is not an error. Flash Player should be blocked — it is a security risk. If you want to enable the Flash Plugin, got to Settings, Webpages, Plugins
-
@Pesala Hi, When I do that, it is working but then I cannot change the playback speed on Udemy, which is very important for me.
I want to be able to change the playback speed also. -
I suggest contacting Udemy. Their technology is clearly out of date, and I would be surprised if they have no plans to release their courses in HTML5 or some format other than Flash.
Do you get the playback controls if you use IE11 or some other obsolete browser?
-
@Pesala I tried all other browsers (Google Chrome, Safari, Firefox) and they all work without any issue. I was thinking from now on I will use Vivaldi but I cannot use with Udemy.
-
@cejno It should work if you permanently allow flash on the site settings under the padlock at the left end of the address bar.
-
@cejno Udemy uses the HTML5 player with the
<video>
element for me. And I can change the playback speed.Deselect the Flash player option in Vivaldi, then try to clear cache (Menu > Tools > Clear browsing data), make sure to select All Time, then Cookies, Storage, Cache and Application Cache. Don't clear passwords (no need).
If you don't want to clear all cookies (understandable really), go to Settings > Privacy > Cookies and filter on
udemy.com
and delete all of them.If it still doesn't work, then maybe the course itself is Flash-only, which is strange but maybe. If so you need to contact Udemy to help you.

@Pathduck I did everything you said and it didn't work. Is it possible that the internet speed is causing this?

When I enable the flash then I cannot change the playback speed.

I doubt the speed is causing it. After all, other browsers work fine right?
But maybe the site for some reason thinks you're unable to playback HTML5 video, and serves you Flash instead. First we need to verify you're able to play video with DRM, there may be something wrong on your system.
Go to the following URLs and check if you can play all of them, especially the ones tagged with DRM
https://demo.castlabs.com/
https://bitmovin.com/demos/drmIf they play, then you need to contact Udemy support and ask why they are serving Flash video when your browser is perfectly capable of playing HTML5 video with DRM.

Hello, I was able to play these videos without any problem.
But maybe the site for some reason thinks you're unable to playback HTML5 video, and serves you Flash instead.
I feel like only Udemy thinks that I am unable to playback HTML5. I don't have problem with Google Chrome when I am using Udemy.
Is there a way that I can tell my browser pull this video from this website as an HTML5 format?Image 1:

@cejno
What is your version of Vivaldi? I notice we've not asked you this and it could matter a lot if you're running an older version.Have you contacted Udemy Support yet?

@cejno What happens if you click on the Blocked Content icon in right of address field?
That could unblock flash content.Yes I can do and the video plays but I cannot change playback speed. I usually watch Udemy videos at the speed of 1.5x but when I enable flash in Vivaldi then I cannot change the video speed.

I am using "Vivaldi 2.10.1745.27 is currently the newest version available." I usually check for update also and hoping a new update might solve my problem, so I use the latest version.
I didn't contacted the Udemy support yet but they usually suggest Google Chrome, when the last time I contacted them for something else. I have no problem with google chrome when I am streaming from Udemy, but Google Chrome is killing my battery so I was trying to use Vivaldi for everything. -
@Gwen-Dragon
Thank you and thanks to everybody for trying to help. I will try that. -

@PathduckHello, everyone.
This Adobe flash error that I was getting is when I was streaming from Udemy from my house. My house internet is little bit slow. Today I was at the coffee shop and the coffee shop internet is so fast. I realized that I have no problem with Udemy while using Vivaldi. This made me think that this problem only occurs while using slow internet.
I am not the expert, but while I right clicked and inspect again in coffee shop with the same video, I saw the difference in the code.
While I was in my house with slow internet, it was streaming as Adobe flash and while in coffee shop with fast internet, it was streaming as HTML5.I tried to add the screenshots also, as you can see on the screenshots:

@cejno If it really is the internet speed which determines if you get Flash or HTML5 content, it would surprise me. Also it would be pretty stupid for Udemy to do it that way - as Flash is being phased out during 2020 and few users will have it installed these days.
Anyway, it would be easy to test such a theory, just going into Dev.Tools and setting Throttling to "Slow 3G" in the network tab. Obviously you'd need to do this in a place with fast internet, like the coffee shop. When I tried, it just set my video resolution to a very blurry 144p but it was still regular video, not flash.
Have you tried in a Guest Profile yet, to exclude any settings or extensions?
https://help.vivaldi.com/article/guest-view/Another thing I notice in your first screenshot is this:
Is that a blank extension icon, if so what extension is it? Have you tried to disable all extensions? -

Hello, right now I am in the coffee shop and when I do that, slowing down the internet it gives me flash error again.
But with regular fast speed, there is no error. Same video.Another thing I notice in your first screenshot is this:
Is that a blank extension icon, if so what extension is it? Have you tried to disable all extensions?This is uBlock origin extension that I disabled on Udemy. I only have that extension and I disabled that on Udemy.

@cejno Well, I'm officially surprised :smiling_face_with_open_mouth_closed_eyes:
Why would they do that, with Flash being phased out?
And you said it doesn't set it to Flash when you're using Chrome/Firefox etc? Or did I misunderstand that bit?
I'd definitely hear with their Support why their site would do that.
