If all you want is to use video instead of webcam, simply remove section of the code from webcam.js that initializes webcam:

face-api/demo/webcam.js

Lines 102 to 130 in fb38360

	log('Setting up camera');
	// setup webcam. note that navigator.mediaDevices requires that page is accessed via https
	if (!navigator.mediaDevices) {
	log('Camera Error: access not supported');
	return null;
	}
	let stream;
	const constraints = { audio: false, video: { facingMode: 'user', resizeMode: 'crop-and-scale' } };
	if (window.innerWidth > window.innerHeight) constraints.video.width = { ideal: window.innerWidth };
	else constraints.video.height = { ideal: window.innerHeight };
	try {
	stream = await navigator.mediaDevices.getUserMedia(constraints);
	} catch (err) {
	if (err.name === 'PermissionDeniedError' || err.name === 'NotAllowedError') log(`Camera Error: camera permission denied: ${err.message || err}`);
	if (err.name === 'SourceUnavailableError') log(`Camera Error: camera not available: ${err.message || err}`);
	return null;
	}
	if (stream) video.srcObject = stream;
	else {
	log('Camera Error: stream empty');
	return null;
	}
	const track = stream.getVideoTracks()[0];
	const settings = track.getSettings();
	if (settings.deviceId) delete settings.deviceId;
	if (settings.groupId) delete settings.groupId;
	if (settings.aspectRatio) settings.aspectRatio = Math.trunc(100 * settings.aspectRatio) / 100;
	log(`Camera active: ${track.label}`);
	log(`Camera settings: ${str(settings)}`);

and replace with simple

video.src = 'url_path_to_your_video';
