video-stream :- help required to dynamically compress or scale down minicap framess

[asolanki-in]

I am using node js to start video-stream and converting received buffer to frames. I am able to achieve minicap stream for connected device on browser. But each image frame size is more that 140kb. Want to reduce it more if at all possible or already done by anyone let me know.

For Reference:

this.proc = spawn("idb", [
		"video-stream",
		"--udid",
		udid,
		"--fps",
		"15",
		"--format",
		"minicap",
		"--compression-quality",
		"0.1",
     "--scale-factor",
		"0.1"
	]);

Scale factor doesn't seems any effect on scale or image
Its sending frame size same as 1.0 value.

Please help to reduce it.
