[WPE 2.38] Hlsjs PlayReady 4.0 Sample App is not working in Sagemcom VA

[elanisinthan-e-infosys]

Created a Sample App for Hlsjs PlayReady 4.0. The sample app is working fine in Microsoft Edge Browser. But in Sagemcom its showing Error loading playback.
So tried whitelisting url using following steps:

• ssh into Sagemcom and vi /etc/WPEFramework/plugins/WebKitBrowser.json
• added "mixedcontentwhitelist":"[{"origin":"https://.", "domain":["http://"]}, {"origin":"http://.", "domain":["http://"]},{"origin":"http://.", "domain":["https://*"]}]",
• Restarted wpeframework: systemctl restart wpeframework
• Using thunder UI I have ran the sample app

After whitelisting also its showing Error loading playback.
Sample app:
shaka3.zip
Logs after whitelisting:
sgm_wlsa_logs.txt
Logs before whitelisting:
sgmerror_samplelog.txt
Error loading playback image:

After whitelisting also its showing Error loading playback.

I am getting here a 404 for https://cdnjs.cloudflare.com/ajax/libs/shaka-player/4.3.1/shaka-player.ui.css in the inspector so I wonder if this could be related.

[calvaris]

First finding, this is not going to work if you don't enable the media capabilities API. Then you need to serve this from https because WebCrypto won't work. Then there are other errors I am still investigating, just commenting now as I suspect I will have to fiddle through several things like this and I don't want to forget the ones I am bypassing step by step.

[calvaris]

Ah, and the first thing I did was switching to https://cdnjs.cloudflare.com/ajax/libs/shaka-player/4.3.1/shaka-player.compiled.debug.min.js as this gives more necessary information to debug.

[calvaris]

I just pushed calvaris/1427 branch. Please try it and let me know if it works.

@elanisinthan-e-infosys , Could you please try the proposed changes? Thank you!

[elanisinthan-e-infosys]

Tested using the proposed changes and have tried with different versions(4.3.2, 4.3.6) of shaka player.
Issue is not resolved. Its showing Error loading playback.
Sample App used:
shaka4.3.6.zip

[calvaris]

I just tried and the original version and 4.3.6 and both work well with that branch. I suspect that you might be missing something in your deployment. So please, ensure the following things:

• That you're building the proper branch calvaris/1427
• Ensure you are deploying and accessing through https for WebCrypto to work. If you are using plain http, WebCrypto won't work.

@calvaris
We are still trying to do the change for https for WebCrypto to work.

May I know that you have tried with test application which is attached to ticket or do you have a your own test application for the shaka player. If yes then can you please share your test application to check on our setup.

Second, if you could also share the details for " https for WebCrypto to work" , what changes you have done from your side. Is the changes in local Apache server side or something to do the changes in test application as well.

Third, if you thing that your patch calvaris/1427 is a generic changes and it is required for m3u8 content then Can you please merge this changes officially so that we can backport it.

Thanks in advance.

The test you shared with a couple of changes. I replaced the shaka player with the debug version to get more information of what was going on and I also added a couple more things to ensure nothing was broken.

shaka3.html.txt

Second, if you could also share the details for " https for WebCrypto to work" , what changes you have done from your side. Is the changes in local Apache server side or something to do the changes in test application as well.

Changes need to happen in the Apache server, yes. From what I know, just a server with a valid certificate would be enough. This would mean that when you load them in Firefox, for example, you see the lock saying that the connection is secure and no message of insecure connections are shown in the browser.

Third, if you thing that your patch calvaris/1427 is a generic changes and it is required for m3u8 content then Can you please merge this changes officially so that we can backport it.

I won't merge this until you ensure me that everything works properly.

@suresh-khurdiya-infosys Do you have any feedback? Thank you!

[suresh-khurdiya-infosys]

We tried with couple of changes in Apache server for "WebCrypto to work" But, it is still failing. Not sure, why only shaka player with PlayReady is failing.
If I try with shaka plater with widevine content then test case is passing.
Same if try with dash player plus playready content then also test setup is working fine.

So, only an issue with shaka player plus play ready content URL. We are still trying it.
