        "rotation": 0,
        "scale": 1,
        "content_mode": "scale_to_fill",
        "blur": 0.5,

    }
}

Enable virtual background.

Parameter	Description	Optional	Default Value
transparency	Sets the background transparency from 0 to 1.		0.0
texture	Sets the file (image or video) as background texture.		null
rotation	Rotates the background texture clockwise in degrees.		0.0
scale	Scales the background texture.		1.0
content_mode	Fits the background texture inside frame. Possible values are: scale_to_fill, fill, fit.		"scale_to_fill"
blur	Sets the background blur radius. Radius in [0, 1] range.		0.0
clear_color	Specifies the color of the area not covered by background texture (e.g. content_mode fit). Black by default. Transparency (the last) is a conventional value only and currently ignored (use 1 for it).		"0 0 0 0"
