Answer 1

Step 1: Find your chrome preferences file: http://www.forensicswiki.org/wiki/Google_Chrome#Configuration

Step 2: Open it and Find the "profile" key

Step3: Under profile there will be a "content_settings" hash, that will have a "pattern_pairs" hash Add this to it:

  "*,*": {
    "media-stream-camera": 1
  }

Final example:

"profile": {
   ....
   "content_settings": {
      ....
      "pattern_pairs": {
         "*,*": {
            "media-stream-camera": 1
         },
         ....
      }
    }
}

WARNING: This will allow all websites access to your camera
