What about an HDMI in?

I won’t mind the latency @nrp

This article on Hackaday looks interesting: delete that HDMI Out and I want to believe this will fit in a Framework accessory footprint…

Ah right: same person also have an HDMI Capture-only board as well…

Ooh! That looks just right for a larger expansion card like the ethernet one. Getting a tiny capture card in an expansion card form factor would be a dream.

I found a device from MicroCenter that has the necessary ports, usb c to hdmi in, but it looks a little long. https://www.microcenter.com/product/645805/inland-hdmi-to-usb-a-c-video-capture-dongle

I don’t know if this directly applies or could be adapted to an expansion card format but I thought the announcement might be of interest to some of you:

“eEver Technology, a subsidiary of eTron Technology, has launched the EJ523D 4Kp60 audio and video capture and streaming processor with a USB 3.2 interface, along with a reference platform currently showcased at COMPUTEX 2023.”

Man that chip alone looks bigger than an expansion card but the capabilities do sound nice

Wow, yea. Good luck getting that into an expansion card.

Yeah, perhaps HDMI-IN in an i/o array as an expansion bay.

Dreaming bigger…an expansion bay geared towards media and content i/o:

  • HDMI-IN
  • HDMI-Out
  • audio line in
  • audio out

Or just a mega connectivity expansion bay…caveat, I have no idea on bandwidth constraints. Any/all of these:

  • Dual USB-A
  • Dual USB-C
  • 10Gb ethernet
  • full size SD Card reader
  • HDMI-IN
  • HDMI-Out

I would absolutely pick up one of these before buying a dGPU expansion bay.

I like that too! I would pay for that! I bought the dual SSD expansion but this sounds way too cool!

I have an Android tablet that has this functionality. Lenovo Yoga Tab 13. I use it both as an Android tablet and as a workbench monitor for troubleshooting Chromebooks and as a second screen sometimes. The way Lenovo appears to have implemented this seems to be that Android doesn’t see the devices plugged in via the micro-HDMI-in.

The tablet was touted as being able to be used as a portable screen for mobile gaming devices like a Switch or even for consoles in some situations. It’s not a perfect solution. The image is a tiny bit fuzzy, but it has made my job easier in a number of ways with the help of a HDMI Female to micro-HDMI-male and a USB-C male to HDMI male cable.

If my Framework could serve a similar purpose, I’d snap one of these up in a second…and recommend them to my boss for the rest of the team.

It’s a shame because CES has come and gone and while I didn’t look exhaustively, there didn’t seem to be any new chipsets/consumer facing products released around HDMI Capture.

There’s a reference design here: GitHub - ultrasemier/ms213x_community

@Maxwell_Edwards, that’s requested in an implementation-inspecific manner elsewhere:
