S-video / composite in on RPi 4 or Zero W

I have a project where I am aiming at video transfer between two RPi´s using a 5.8ghz FPV transmitter and receiver. On the RPi Zero W there is an analogue video / TV out that I will use for the transmitter but I am having a hard time to find a way to get analogue video in on the RPi (RPi4 or Zero W) I would like to use a 5.8ghz FPV receiver from Boscam but that is not a must. I see that Auvidea har a few HDMI boards and PiCapture has a board supporting progressive video but I have not found anything with analogue / composite video. Preferably using the Picamera connection. Any advice is appreciated.
Thanks a bunch!

Thanks for this. I am hoping for a more embedded approach than EasyCap though

As you have already found input devices are HDMi or NTSC/PAL. Apart from the USB Easycap I am not aware of any other Composite Input solution.

Not off the shelf, but the Analog Devices ADV7282-M chip does analogue video (composite, S, or component) to CSI2, andd is supported by the kernel drivers.
I'm not aware of a commerically available board for it beyond the
Eval board

There are FPV receivers with a built-in USB capture device.

Good point!
And cheap too.

UVC so shouldn't need a driver.
Not a recommendation, just a search result.
