How to use CEF for Spotify

[RABBITSV]

I tried to use CEFSharp for open Spotify WebBrowser (https://open.spotify.com/browse/featured), and i got page with message "Enable player in your browser (Under Protected content, make sure Allow site to play protected content is enabled.)".

I used different command line arguments:

Code: Select all

settings.CefCommandLineArgs.Add("persist_session_cookies", "1");
settings.CefCommandLineArgs.Add("enable-automatic-password-saving", "enable-automatic-password-saving");
settings.CefCommandLineArgs.Add("enable-password-save-in-page-navigation", "enable-password-save-in-page-navigation");
settings.CefCommandLineArgs.Add("cache-path", @"D:\Chrome\1");
settings.CefCommandLineArgs.Add("enable-widevine-cdm", "1");
settings.CefCommandLineArgs.Add("ppapi-flash-path", Path.Combine(Environment.CurrentDirectory, @"pepflashplayer64_29_0_0_113.dll"));
settings.CefCommandLineArgs.Add("enable-npapi", "1");
settings.CefCommandLineArgs.Add("allow-running-insecure-content", "1");
settings.CefCommandLineArgs.Add("enable-media-stream", "1");

And succesfully registred WidevineCDM additionaly:

Code: Select all

Cef.RegisterWidevineCdm(Path.Combine(Environment.CurrentDirectory, @"widevinecdm"));

Ineffectually.

Then i downloaded a sample application from official Spotify page: http://opensource.spotify.com/cefbuilds/index.html (cef_binary_3.3325.1758.g9aea513_windows32_client.tar.bz2 - test program), and run it:
cefclient.exe --proxy-server=144.76.62.29:3128 --cache-path=D:\Chrome\4 --enable-widevine-cdm
The result is the same.

Spotify local client is based on CEF, therefore it must work. But how?

See the documentation for CefRegisterWidevineCdm

It registred without errors on callback and logs. Test page give out that:

Does the "Test DRM video playback" link work with the Widevine asset? A license error is expected but the video should play for a few seconds before stopping.

Also, what OS are you using? Does it work in Google Chrome with your proxy configuration at the same CEF version?

[RABBITSV]

OS is Windows 7 SP 1.
In cefclient.exe Shaka give out this:

cefclient.exe --proxy-server=144.76.62.29:3128 --cache-path=D:\Chrome\4 --enable-widevine-cdm --widevine-cdm-path=D:\Chrome\WidevineCdm --widevine-cdm-version=1.4.9.1070

My fault is that I used the downloaded WidevineCdm from forum. I did not understand how to get it from Google, but downloaded it myself.
