I made the code changes in my project,but I am still get parse exception.my issue is I am getting the downloadable urls as null,,for videoId=RybTtWxKQns; from here
IEnumerable downloadUrls = ExtractDownloadUrls(json); which is calling fro GetDownloadUrls(string videoUrl, bool decryptSignature = true) method of DownloadUrlResolver.cs

[flagbug]

Should be fixed with #151
