zoom on phone

[toto6976]

Hi,
Is it possible to have a zoom with "--video-source=camera --camera-id=1" ?

Camera zoom is not implemented. Depending on what you want, --crop=… might fit your needs.

I don't know how to use --crop . Can you see me ?

You must specify a rectangle width:height:x:y which is fully inside the input size.

For example, if you capture at 2560x1920, then you can crop 500 pixels on every side: --crop=1560:920:500:500.

I would like to enlarge the area located at the top left for example. I don't see how to do it with the --crop command?!

[rom1v]

For the top left quarter: --crop=1280:960:0:0.

[toto6976]

Great ! is it possible to make the top even bigger??

i understand how to do it : --crop=960:720:0:0 is what i want to have.

Thank you
