First an observation.

When using CamRanger only the Canon LCD is visible in CamRanger, ie the ML overlays are not.

So the request is, can the Canon LCD output that CamRanger taps into be megred with the ML overlay feed, before it is fed out of the camera.

This way any piece of hardware or software that took the Canon LCD feed would also see the ML data.

I'm assuming this camranger uses usb?
Not even the canon gui is fed through usb.
It's just a 4:2:2 mjpeg stream.

Yes the Camranger gets its camera data through the USB.

I'm still ignorant on this.

Are you saying that ML overlays that we see on the LCD can not be merged with the LCD that Camranger sees through the USB?

ItsMeLenny

Correct.

You'd have to figure out how to write to the mjpeg framebuffer.
But they wouldn't be overlays then, they'd be burned into the preview.

Got it. Many thanks for clarifying.
