[video_player_videohole] DRM not decrypting (VMX)

[mhoeckner]

Hi all,

the license callback works fine and is called. Also the plugin gets the ey from license server, but player does not decrypt the stream.

I created an example code with our DRM provider here: https://github.com/mhoeckner/flutter_tizen_test

To start the streams you need a password - I will send it @haesik and @swift-kim

With the "standard" free google drms the examples work.

You got any ideas what's wrong here?

Thakn you regards Markus

Hi, @mhoeckner Have you add the required privileges in tizen-manifest.xml?

[swift-kim]

Hi. Thanks for reporting.

Do you know if this problem was present in the preview version of the plugin (hyue7's PR) or is it a regression introduced after switching to the released version?

[mhoeckner]

Hi,

@hyue7 - sry - updated my code - available in https://github.com/mhoeckner/flutter_tizen_test

But after adaptations nothing changed - got the correct permissions in other local branch that I tested - sorry for confusion

@swift-kim - the problem already existed in preview version. We weren't sure if we caused the problem - until now - our DRM works in Shaka Web 4.3.5 and ExoPlayer with DASH / Widevine

[hyue7]

Hi, @mhoeckner The stream in your example can't play, and throw error: [E] [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: DioError [bad response]: The request returned an invalid status code of 500.

[mhoeckner]

Hi @hyue7

this i a dev env and so the contract has been revoked. I updated repo - please pull - should work now.

Sorry for the inconvenience, regards Markus

@mhoeckner hi, Markus, this bug is also tizen platform bug, it has been fixed, but now I'm not sure when OTN for this fix will be scheduled. Since this issue is caused by not supporting cbcs encryption mode, you can use cenc mode encryption in server side for now. Sorry for incovinience.

[mhoeckner]

@xuelian-bai - hi Xuelian, thanks for investigation - we are looking forward for update.
