Hi,
For a particular project I need to add video and snapshot recording to the device I'm building. I have a Zynq-7000 FPGA performing the video manipulation and all of that is working fine. The customer wants to add video and snapshot recording (a.k.a DVR). One solution I thought of was to feed the video output from my FPGA to a RPi CM4 via the MIPI interface, build a DVR application inside the RPi, and route the HDMI output back to the FPGA. The control signals can be passed via uart or GPIO between the FPGA and RPi.
However, the RPi compute module has been out of stock for more than a year and things dont' seem to be improving so far.I could probably find one or two on ebay or similar, but I don't want to use somethign I can't source in quantities 6 months down the line. So I think I need to find an alternative. Ideally, I want something that I can plug into the main baseboard I am building (like the RPi CM4 does) for reliability. I have seen many RPi experts on this forum, and I am hoping to get some recommendations for alternatives that are easier to source.
Looking forward to hearing from you!

p.s If you know of a better approach to adding DVR functionality compared to my use of RPi, please do share as well! I have considered switching to KRia SOM but it will not fit the budget, plus that is suffering from availability issues too.
