Ubuntu18.04

The libwidevinecdmadapter.so link in your post above links only to text/xml.

try this one

libwidevinecdmadapter

It's strange. I used this solution on 2 laptops and it works.

1. Did you use the right setup in the point 2?
2. Do you use also another user agent besides the one mentioned in the point 2? If yes then switch it off.
3. Check also what you have in the file widevine_config.json. It should be located in /usr/lib/x86_64-linux-gnu/opera/resources
   My file contains
   [
   {
   "preload" : "/opt/google/chrome/libwidevinecdm.so",
   "plugin" : "/opt/google/chrome/libwidevinecdmadapter.so"
   },
   {
   "preload" : "/opt/google/chrome-beta/libwidevinecdm.so",
   "plugin" : "/opt/google/chrome-beta/libwidevinecdmadapter.so"
   },
   {
   "preload" : "/opt/google/chrome-unstable/libwidevinecdm.so",
   "plugin" : "/opt/google/chrome-unstable/libwidevinecdmadapter.so"
   }
   ]

1. Put files libwidevinecdm and libwidevinecdmadapter to /opt/google/chrome
   If that folder doesn't exist then create it. If you don't have those files you can
   download them from my googledrive
   libwidevinecdm
   libwidevinecdmadapter
2. Install User-Agent Switcher addon and setup it to chome Linux and the highest chrome number
3. Watch Netflix

If I use a user agent switcher, Netflix loads and neither gives me a widevine error nor redirects me to the support site (https://help.netflix.com/en/node/23742).
But the problem is that the video is loading forever (https://imgur.com/WWyH4vt).
And it doesn't matter if I have Chrome installed or not, i. e. if there's an additional libwidevinecdmadapter.so file, the video will still load forever. The widevine_config.json file is also configured correctly.

I don't know what I'm doing wrong...
Any help is appreciated :smiling_face_with_open_mouth_smiling_eyes:

BTW, it works in Vivaldi out of the box.

I used Opera 52 on Ubuntu and Opera 51 on Manjaro.

As we all see from the above, opera expects to find the widevice libs inside chrome's installation path. Why not add the

/usr/lib/chromium-browser/

path to the above. It is where ubuntu's chromium package installs the same libs. I mean, opera checks for the ppapi flash in various locations in order to find it, so why not look for the widevine libs elsewhere? Editing these files to add the proper path, as far as I know, breaks opera because it somehow checks the "originality" of them and fails to start.

And all that is just a part of a bigger discussion about customizability, e.g. the default search engines follow the same rules and cause the same problem if their file is altered.

@jimunderscorep I create and copy libwidevinecdm.so & libwidevinecdmadapter.so manually into /opt/google/chrome and it work !

thanks guys for your help.

PS: in opera://components I have always nothing

$ cat /usr/lib/x86_64-linux-gnu/opera/resources/widevine_config.json
[
{
"preload" : "/opt/google/chrome/libwidevinecdm.so",
"plugin" : "/opt/google/chrome/libwidevinecdmadapter.so"
},
{
"preload" : "/opt/google/chrome-beta/libwidevinecdm.so",
"plugin" : "/opt/google/chrome-beta/libwidevinecdmadapter.so"
},
{
"preload" : "/opt/google/chrome-unstable/libwidevinecdm.so",
"plugin" : "/opt/google/chrome-unstable/libwidevinecdmadapter.so"
}
]

And as it seems, all of them are the ones that come with the chrome packages.

/home/user/.config/chromium/WidevineCdm
This folder is empty but may work for you.

/usr/lib/chromium-browser/WidevineCdm
Contains the manifest.json

Files found were....
/usr/lib/chromium-browser/libwidevinecdmadapter.so
/usr/lib/x86_64-linux-gnu/opera/resources/widevine_config.json
/usr/lib/x86_64-linux-gnu/opera developer/resources/widevine_config.json

I'm running Opera version 49.0.2725.39

Inside of it there should be a folder with Widevine's version number. I'm on Windows but I don't think it is much different in Linux.

I have nothing in opera://components and it doesn't work.

Thanks

For chromium I have install the package chromium-widevine who contain:
/usr/lib/chromium/libwidevinecdm.so

In opera profile directory I have no plugins directory.
I don't know what I must copy and where.

Do you know where Opera download Widevine and where it copy it ? maybe I can do it manually.

In chromium //components I have:
SSL Error Assistant - Version : 4
CRLSet - Version : 4194
File Type Policies - Version : 14
Origin Trials - Version : 0.0.0.0
Signed Tree Heads - Version : 619

Thanks
