Flash Player in own CefBrowser after 2020

[KlayKlay]

Hello,

i have developed a C# Webbrowser with CefSharp (Chromium embedded Framework) i loade the Flash plugin so flash pages still do work. If i dont update my own developed webrowser, like for example stay at CefSharp 83.4.20 & Flash 32.0.0.414, is it still possible to use the webbrowser with its flash after 2020?

The thing is that Flash is a mandatory thing for my Webpage and Game. Its 100% nessecary and there is no other way for me around it. 

So i extra developed the Webbrowser in C# to still continue use Flash.

Plugin: pepflashplayer64_32_0_0_414.dll

CefSharp: 83.4.20

Please dont mark as spammed. or at least tell me what im doing wrong so its marked as spam

Thank you so much!

Is this for your personal use only? It will be forbidden to distribute Flash Player to anyone else! (It already needs a license, but there will be no license).

Yes. this is perfectly for myself.

Currently it does work perfectly like i want but i just want to know if i am able to use it after 2020 the same?

Thank you very much!

Embedding Flash Player in any application requires a Flash Player distribution license.  See https://www.adobe.com/products/flashplayer/distribution.html and click on the option that best describes your situation.

i dont belive i require a license for my personal own use. I wont distribute it.

Currently it does work perfectly like i want but i just want to know if i am able to use it after 2020 the same?

Thank you very much!

Ok, if you don't need to distribute it, you will still have to deal with it self-blocking at the end of the year. I read there is a whitelist of sites. I suggest you do tests changing the date to next year.

i just found out about the "mms.cfg" so it says i can put "EnableWhitelist" than it should allow me to allow specifi sites. I put the mms.config in the same folder as my: "pepflashplayer64_32_0_0_414.dll" and i changed the mms.cfg content to:

SilentAutoUpdateEnable=1
AutoUpdateDisable=0
EOLUninstallDisable=0
EnableWhitelist=1
WhitelistUrlPattern=192.168.2.35

Now i changed my local PC time to 2021 and in my local apache webserver there is now a flash icon with a blue information icon in it. When i click on it it redirect me to https://www.adobe.com/products/flashplayer/end-of-life.html

So it seems to not work correctly.

Does someone have a idea what im doing wrong?

Thank you for your help!

Edit: Sorry, I had a little brain cramp there.  😄

My guess is that your mms.cfg settings aren't being applied.  Chromium doesn't read from the standard system location.  You'll need to look at the chromium documentation for the appropriate location in Chromium's filesystem.  Also, if you're loading files locally, you need to have the appropriate directives set (e.g. AllowListURLPattern=file:///path/to/whatever), and maybe EnableInsecureLocalWithFilesystem=1 as well. 

I'm not sure that we can write logs from inside Chrome's sandbox either, but we're able to trace to the JavaScript console now, if you can watch it in the context of your running application.  Check out the TraceOutputEcho directive for more info there.

Hi,

did you manage to find a way with CefSharp/mms.cfg?

Thanks
