What is your idea?

Currently all still camera images are scaled to the size requested by iOS. Suggestion is to use the aspect ratio of the input image.

My stills are 1600x1200 (4:3 ratio) but are squished to 16:9 ratio.

Any more details?

I believe this can be changed on this like of code:

node-red-contrib-homekit-bridged/src/lib/cameraSource/index.js

Line 170 in d96c745

let resolution = request.width + 'x' + request.height

Additional comments?

streaming view (proper scale):

Any code or functions to add?

After more research... scaling would not help here. The still image needs to be cropped down to a 16:9 ratio, centered at 50% of the still image height or width (whichever needs to be cropped).

In my case I was hoping to change the still image source from:

-i http://10.0.1.3/snap.jpeg

to:

-i http://10.0.1.3/snap.jpeg -vf "crop=1600:900:0:150"

Which would output a proper image - but it doesn't seem to be working ... there must be something conflicting with that ffmpeg command later on in the code.
