From the article:

> At this time an open source HDMI 2.1 implementation is not possible without running afoul of the HDMI Forum requirements.

I wonder on what basis. Perhaps an obligation to ensure the software resists reverse-engineering?

I assume that Blu-Ray is similar. As I understand, there are no fully open source implementations of a video decoder for Blu-Ray discs. (Is that still true in 2025?)

As far as I am aware VLC Media Player is capable of playing blu ray dics:

but you have to install some additional files:

If this does not satisfy your claim "there are no fully open source implementations of a video decoder for Blu-Ray discs" tell me where I am wrong.

		Hat tip. I was unaware. When I looked deeper, it requires you to supply the encryption keys for each disc. I highly doubt this method is "approved" by the Blu-Ray consortium. I don't even know the legality in highly advanced economies.
