Re: Is it possible to stream movies from a Nikon D5200 at its supported resolutions?

HI,

I have actually to correct myself.

Nikons can switch their Liveview size.

Options:

	320x240	QVGA
	640x480	VGA (default)

and:
	1024x768 XGA

The XGA mode is available apparently on:

	D850, Z6, Z7, D7500, D500

Not on: p330, d3300, d3400, d3500, d4, d5200, d5500, d5600, d7100, d7200, d750, s9700

see below (XGA is the "3" value in the enum)

cameras/nikon-coolpix-p330.txt:Property 0xd1ac:(read only) (type=0x2) Enumeration [1,2] value: 1

cameras/nikon-z7.txt:Property 0xd1ac:(readwrite) (type=0x2) Enumeration [1,2,3] value: 2

The list is not complete, as I do not have it for all cameras.

I hooked it up as "liveviewsize" option in current GIT.

Ciao, Marcus
