[DRM] License-server key-request fails

[jaylinski]

Description of the issue

When I'm trying to play a DRM protected video via inputstream.adaptive, the request to the license-server fails.

I'm experiencing this issue with the following stream:

#KODIPROP:inputstream=inputstream.adaptive
#KODIPROP:inputstream.adaptive.manifest_type=mpd
#KODIPROP:inputstream.adaptive.license_type=com.widevine.alpha
#KODIPROP:inputstream.adaptive.license_key=https://drm.ors.at/acquire-license/widevine?BrandGuid=13f2e056-53fe-4469-ba6d-999970dbe549&userToken=https://drm.ors.at/acquire-license/widevine?BrandGuid=13f2e056-53fe-4469-ba6d-999970dbe549&userToken=<token>
https://orf1.mdn.ors.at/out/u/orf1/drmqxa/manifest.mpd

Important: The license-server URL requires a fresh token for the userToken-param which can be requested by calling https://api-stage-tvthek.orf.at/livestream/_token and copying the base64-value.

This stream may be geo-blocked to Austrian IPs.

Expected behaviour

Kodi (inputstream.adaptive) plays the stream.

This stream may be geo-blocked to Austrian IPs.

Actual behaviour

Kodi doesn't play the stream and shows an error. (See License server returned failure error in logs below)

The DASH reference player (https://reference.dashif.org/dash.js/latest/samples/dash-if-reference-player/) can play the stream without issues.

Is there a way to get the response content from the license-server request? (Failed: HTTP returned error 400)

It would probably help to debug this issue.

[matthuisman]

if the server is returning 400 it means your not providing enough or the correct data.
It isn't an Inputstream Adaptive issue unfortunately.
You'll need to use EME logger or chrome dev tools to find out the type of request it makes, the headers it needs, the payload type and the response type

[glennguy]

It's possibly a VMP issue.

Try it on an Android device if you have access to one. If it works then VMP is to blame unfortunately.

[glennguy]

Is there a way to get the response content from the license-server request?

Yes, you could try running it through something like mitmproxy

[jaylinski]

@matthuisman @glennguy Thanks for the tips! I think VMP is not the issue, since the stream doesn't work on my (rooted) Android phone.

I used mitmproxy and devtools in order to inspect the requests. The DASH reference player sends some binary blob to the license server, while Kodi sends some JSON non-binary data:

Is there any way to change the payload-type? (I read https://developers.google.com/web/fundamentals/media/eme, but it didn't really help me to understand if there are different payload-types...)

[matthuisman]

Ummm. That json data is the response from their server... Not the request payload

[jaylinski]

@matthuisman Have a look at the picture in the middle. It shows the request-payload.

Edit: the request-payload is not json... I see that now. But it is still not the same payload-format as the DASH player is sending.

[matthuisman]

https://github.com/xbmc/inputstream.adaptive/wiki/Integration#inputstreamadaptivelicense_key

So try add ||R{SSM} to the license url.
(Not sure why json would be the default...)
Most of the time R{SSM} = raw format is used

this isn't an issue in IA. General help like this should be done in the Kodi forum. And these issues kept for actual bugs

[jaylinski]

Thanks for your help! I totally missed the info in the wiki 🙈.

I think I'll get it to work with this info! Thanks for your quick replies and for your work on this addon! Greatly appreciated!

[jaylinski]

It works now. If anyone else has the same issue, this is the config which works for me:

https://orf1.mdn.ors.at/out/u/orf1/drmqxa/manifest.mpd

[matthuisman]

I'll look into making R{SSM} the default payload type if none provided
