As I have now finished up the amplifier boards (STE100, SWE300) I wanted to start work on the controller system for the AVR. I have already started on the faders for volume control and plan on controlling them with a STM32 over I2C as shown in the diagram bellow. My main hurdle will most likely be the LCD or if I am ballsy enough, a proper HDMI I2S de-embedder with a switch and a DSP (Analog Devices Sharc). Just wanted some thoughts on the diagram and what you would do if you where to make something like this?

Just a thought, but you might want to look at an RPI 4 for a lot of what you're after. I believe it can support CamillaDSP and has a lot of GPIO pins for hardware control. It has a built-in HDMI controller and, since it can run linux, offers all kinds of GUI opportunities. Along with connectivity so it wouldn't be (too) difficult to control your setup via Ethernet or Wireless options. Or, of course, with a mouse/keyboard/monitor setup.
Linux has a number of multimedia systems that also might be useful w/regard to your project. VLC can play all kinds of video formats, pretty much out of the box, so to speak.
I used an RPI-like single board computer for about a year as my personal computer. It had 8 cores, was pretty fast and was far smaller than the monitor it was connected to. All for less than $100. Those things are great for the kind of thing you want......and with a lot less engineering on your part.
