As far as I can tell, there isn't-- I think that the issue is that the way it gets the data is by running a command to save an image, then getting that images data-- here's a bit of a workaround that I find works, just delete the file that gets saved immediately. A bit annoying, but eh
const nw = require('node-webcam');
const fs = require('fs');
let cam = nw.create({
callbackReturn: 'buffer'
});
cam.capture('delete', (err, data) => {
if (err) {
console.log(err);
} else {
// Data is buffer w/ image
fs.unlinkSync('delete.jpg');
}
});
ah dang, this is bad limitation as write/reads off a drive are obviously much slower then memory, wish the buffer option just returned the buffer without saving, kinda makes it pointless to even have the callback controls.
I've tried playing around with saveShots, output and callbackReturn, but non of them seem to allow me to stop the saving of the photo as a file. I really only need the photo in memory though, so it's just unnecessary overhead for me.
