Hello,
I’m facing the same issue. Some devices report the following error when attempting to play Live or Catch‑up streams:

“Failed to execute ‘createMediaKeys’ on ‘MediaKeySystemAccess’: Unable to create CDM.”

We are using DASH streams with the HEVC codec and Widevine DRM, and the player is Shaka Player v4.11.4.

The problem occurs across all device groups (LCD, NanoCell, QNED, OLED). Our application is available on 2022–2025 models, but the issue mainly affects 2024–2025 devices.

I’m using same code base on webOS and Tizen devices. “Unable to create CDM” error occurs only on webOS devices. Maybe it is something device dependent? Also, yesterday I have checked, switching from HEVC to AVC does not solve the issue.

Hi, I work on the Shaka team.

We’ve had similar reports, solely on 2025 models. We rely on system capabilities and the CDM to establish encrypted playback. We integrate with EME as described per spec. Unfortunately there isn’t much left to do when createMediaKeys promise rejects our request.

I suspect there’s an issue with the Widevine CDM shipping with these newer models. Happy to discuss this more indepth.
