Hi again,
finally i have good news to report
. I got it working, although not in the browser i had expected. I am not quite sure what actually did the trick but i will try to explain what i did.
Yesterday i installed
Chromium55 and
Widevine-plugin55. I enabled the Widevine plugin but it was still not working.
After that i read the posts, quoted by Alien_Bob and tried out those commands after closing all browsers:
Code:
rm ~/.config/wine-wininet-installer.accept-license -> there was nothing to delete
rm -rf ~/.wine-pipelight -> the folder was deleted
I restarted Firefox and reinstalled Silverlight. Then i was trying again with no success. Suddenly i tried it out in Chromium and it was working, without User Agent Switcher. I was presenting myself as Linux OS and nevertheless the stream started (with subtitles and sound). I was astonished. I personally think, that those two removals solved my problem after closing all browser windows.
Now i can watch those streams. We will see what would happen upon a next update.
I read somewhere that Firefox50 would support Widevine built in it, if you configure it with a special option at build time. I would like to try to upgrade my Firefox and see what the result would be. Is there a way upgrade the browser in an easy way? There was a time when Alien_Bob was creating such SlackBuild-packages and i was easily installing them, but i cannot find them anymore.
