Is there anyway to enable widevine cdm adapter in Chromium? I am trying to get netflix to play in Chromium. I turned on the proprietary codecs option but it is still complaining about missing the widevine component. It seems that the source files for widevine is not available in the public Chromium source tree. I copied the widevincecdmadapter.dll from Chrome binaries to the Chromium compiling folder. But it doesn't pick it up automatically. I guess there might be switch we have to turn on in order for it to work?

Widevine key system is not supported in Chromium. You have to use Google Chrome to play Netflix.

Why is the key system not supported?

I found a file named "widevine_cdm_version.h". Added two lines into it:

#define WIDEVINE_CDM_AVAILABLE
#define WIDEVINE_CDM_VERSION_STRING 1.4.6.758

That did get Chromium to load the widevinecdmadapter.dll. Then I tried to play netflix in Chromium. It no longer complains about missing widevine. But somehow the video playing page always shows spinning wheel and the video never starts to play. Something else is missing.

Hi,

 

I guess that chromium's open source does not support to plug-in Widevine CDM automatically.

It means that Widevine CDM should work as external process with the below option

 

example option) --ppapi-out-of-process --register-pepper-plugins="widevinecdmadapter.dll;application/x-ppapi-widevine-cdm"

I tried it but it didn't work, at least not for netflix. Netflix still complains about missing widevine component when I start Chromium with the options you mentioned.

Could you try it on Android?

On Android, there is Widevine support and we tried that before and worked.

I also noticed that the web page (both netflix and google play) issued a request for a mime type "x-ppapi-clearkey-cdm" which Chromium responds as not handled. I read up some docs on EME and it is said that Clear Key support is always required. Is this clear key support implemented by another plugin?

Hi, 

It's possible to do EME with chromium on Linux, but you need to recompile chromium with a patch.

we track the progress of this bug for Ubuntu here : 


which is link to the crbug here with instructions to build a working chromium :

Yes. We got it working eventually by modifying the file widevine_cdm_version.h, but only on m40. On m38, we couldn't get it to work after various attempt.
