The init data may be malformed or in an unsupported format. error.data[0] is an error message string from the browser. error.data[1] is the error object from the browser. error.data[2] is a string with the extended error code, if available.

I can reproduce the issue with v2.5.0-beta3
According the drm provider in v2.0.3 the issue doesn't happen due to changes in the pssh.

@avelad I would be interested in knowing more about the pssh changes you mention. Could you reach out to me? [email protected]

[avelad]

I just tested with Edge 18 in v2.02, v2.0.3 and v2.5.0-beta3 and It doesn't work.
With Edge 15 works in 2.02, v2.0.3 but not in v2.5.0-beta3
It a bit curious...

Note: the same manifest with Widevine in Chrome/Firefox/Opera work without problem.

The stream works with http://reference.dashif.org/dash.js/v2.9.3/samples/dash-if-reference-player/index.html

So, I think that is not a browser error

[cristioltean]

Hello ,

I have sent an email to [email protected] with more data : mpd link , license serve url.
Also a screenshot with the decode initData used when doing a session.generateRequest call.
It will help us allot if you can provide some information of how this initData is generated , I believe that the player crashes because it cannot get exact structure it needs to create it.
Regards,

Cristian

@cristioltean - The error code indicates that the init data is incorect. If you could provide me with the information you sent to [email protected] we can help determine the root cause

[cristioltean]

Hi @johnsim if you can provide me an email address or another way to send you the info I will do it ASAP.

@cristioltean ,in this comment you have the mail.

[cristioltean]

@avelad Thanks Alvaro , I have forwarded the email to you @johnsim

[johnsim]

Thanks, @cristioltean, @avelad - the Microsoft PlayReady team is evaluating the data now. I will update this issue with our findings.

[avelad]

@johnsim , do you have any update?

[cristioltean]

Hello Alvaro,

I was talking with John via email and currently we are trying to understand why the initData used to generate a license request is not compatible for Shaka.

Latest question from him was if this Star channel is working with Widevine , as far as I know in your tests Widevine is working fine.

[avelad]

@cristioltean , Yes, Widevine is working without problem in Chrome, Firefox and Opera.

The pssh data in the media is bad. It contains a valid Widevine pssh box, but the pssh box for PlayReady has an invalid System ID. The correct System ID is "9a04f079-9840-4286-ab92-e65be0885f95" but you have "9a04f079-9840-4286-ab92-e65be0889f95".

[avelad]

@TheModMaker, Would it be possible to add a more explicit error code for when the content does not have a valid system ID?

[cristioltean]

Hi Alvaro , what I can see it's that the the System id in the init segment indeed is not 9a04f079-9840-4286-ab92-e65be0889f95

I will check this with R&D.

Thanks @TheModMaker

@avelad We don't like assuming init data formats or System IDs. That could be a valid System ID for some unknown key system, so we don't want to throw an error for it. We just give the data to the browser and let it handle it. But we could use the data in the manifest to validate the expected System IDs (at least for the ones we know about). You could file a feature request for that.

[cristioltean]

Hello , indeed the system id was not correctly set in the init segment which was causing this , after fixing the typo playback is working ok .Closing ticket for now.
thanks for the help.
