In the first few lines of $youtube-video/youtube-video.js the initial URL value is hard-coded and the youtube video Id is appended to the string as follows:
url: "http://www.youtube.com/get_video_info?video_id=" + id
Chrome policies seem to have blocked the use of this protocol for some types of requests. This can be overcome by just changing it to "https". This might be easily overcome with a try/catch of some sort, but I have not tested it.
Thank you for this project! It was very helpful for me!
