Black screen

[Adel51]

Hello,
I'm french.
I tried the MMM-VideoPlayer module but now the screen is black.
Can you help me?
The module needs depedencies/modules to be installed?
regards,

var config = {
address: "localhost", // Address to listen on, can be:
// - "localhost", "127.0.0.1", "::1" to listen on loopback interface
// - another specific IPv4/6 to listen on a specific interface
// - "", "0.0.0.0", "::" to listen on any interface
// Default, when address config is left out, is "localhost"
port: 8080,
ipWhitelist: ["127.0.0.1", "::ffff:127.0.0.1", "::1"], // Set [] to allow all IP addresses
// or add a specific IPv4 of 192.168.1.5 :
// ["127.0.0.1", "::ffff:127.0.0.1", "::1", "::ffff:192.168.1.5"],
// or IPv4 range of 192.168.3.0 --> 192.168.3.15 use CIDR format :
// ["127.0.0.1", "::ffff:127.0.0.1", "::1", "::ffff:192.168.3.0/28"],
