Hey @brianschrameck this looks good! Can you please add a test? Please add it here https://github.com/twilio/twilio-video-processors.js/blob/master/tests/unit/spec/utils/support.ts#L4

Here's my suggestion for the test:

  describe('For server side rendering', () => {
    let originalWindow: any;

    before(() => {
      originalWindow = root.window;
      delete root.window;
    });

    after(() => {
      root.window = originalWindow;
    });

    it('should return false', () => {
      assert.strictEqual(isBrowserSupported(), false);
    });
  });

Good call, @charliesantos. Should be all set now!
