    • HDCP had flaws and keys up to version 2.1 were extracted/reversed. In addition to that there is hdfury device that legally and following HDCP licencing terms downgraded 2.2 to lower 2.x versions to provide compatibility. They got smarter and blocked downgrading in later versions. Blocking HDCP older than that would also break compatibility with devices that don’t support versions of the standard newer than late 2012. Add a capture card and you are set.
    • Widevine L1 keys were extracted from a Qualcomm CPU in 2021. They are also stored in Intel CPUs in SGX which had so many flaws over the years I’d be surprised nobody grabbed keys at some point
    • Both audio and video has to be decrypted and analog at some point - you can capture it if you have the hardware and willingness to e.g. grab it at a LCD display ribbon. Not as good/convenient as decrypting it, but it is an option.

    4k 120Hz HDR is what current gen consoles can output right now and what is becoming common even on mid-range TVs (quality of HDR aside). I’d expect you’d want most of that experience or future-proof solution that would allow that when you get a new TV.


    • No SBC that I know of can handle 4k 120Hz HDR output, so getting the most of moonlight is not possible.
    • Low latency decode requires some work to get running
    • AV1 encode/decode has even more latency, do you will be running higher bitrate h264, which in turn means wired network connection is recommended.
    • Streaming services limit 4k and/or HDR access on a lot of content to locked devices. E.g. Netflix only guarantees 720p sdr when watching in a browser - how much more you get depends on the deal with the copyright holder.

    Tl;dr; a long, active fiber HDMI cable + USB over IP might be cheaper, better and easier. That’s what I ended up buying despite the cable length being 60m (200ft).
