I have an app to display DRM videos using shaka. I made my own custom controller. Everything works fine, except for the playback speed. Why doesn’t it work? Is it that video tags can’t use playback speed?

We cannot check 3rd party player issues. For questions about Shaka Player, please contact Shaka Player support. For your information, the native player does not support changing media playback speed. Thank you.

So, if I change the playbackspeed via the element video tag, it won’t work, because webos doesn’t support it. Is that so?

That’s right. When playing media, only seek and live seek are supported. For more information, please refer to [Streaming Protocol and DRM](https://webostv.developer.lge.com/develop/specifications/streaming-protocol-drm). Thank you.
