I can reproduce the same behaviour - thanks for reporting.

I've opened internal b/228424439 to report this to the relevant team.

It looks like you are trying to cast to an emulator. Cast requires L1 support, and L1 support requires real hardware.

[icbaker]

@fredgc I don't think there's any casting happening here, this is just local playback. It works on the API 30 emulator, but not the API 31 one. See b/228424439#comment3 and comment4 for some more diagnosis details.

Hi @icbaker - I would be interested in the outcome of this ticket. Apparently when WideVine L3 is forced for a stream where only HDCP is enforced, we get the above mentioned error, having the following cause:

Cannot cast android.hardware.drm@1.0::ICryptoPlugin obj to android.hardware.drm@1.4::ICryptoPlugin plugin

Is there a workaround or solution for this? (Your last comment suggests to be an internal error) This is happening on the DRM system of all the latest Android versions 10 ... 12,13

My suspicion is that once the HDCP is required, this implies as well the presence of the hardware decoded stream, for security reasons, because WV L3 is not considered secure enough.

@tibor-leo-safar-accedo Is your problem on the emulator? This thread is specifically about a known issue with Widevine on API 31 emulators. If you have a non-emulator Widevine question and you're a Widevine partner you can also get support directly from them: https://www.widevine.com/contact.

In general we focus on issues with ExoPlayer's Widevine integration on this issue tracker, rather than general Widevine questions (since we are not Widevine experts).

Hi @icbaker - this is on real devices. Now I am not sure if this is a real issue or it is more a DRM configuration issue of the streams? Anyhow, thank you for the response, since my question is physical device related, it will need an another solution.

@tibor-leo-safar-accedo that is a policy question and unrelated to this tracker or this forum. If you are a Widevine licensee (or would like to become one) you can reach out for Widevine support at https://www.widevine.com/contact
