libvideo Get age restricted YouTube videos by querying using a user credentials

Whenever you try to get a video has an age restriction you get the below exception where YouTube asks you to login to confirm your age. It would be great if we can get the video using a user credentials.

VideoLibrary.Exceptions.UnavailableStreamException

Hi, maybe can this code be integrated relatively easily? @omansak @zerodytrash zerodytrash/Simple-YouTube-Age-Restriction-Bypass

Got it!

Set target framework to .NET Standard 2.0
Add

var status = playerResponseJson.SelectToken("playabilityStatus.status")?.Value<string>(); 
if (status == "AGE_VERIFICATION_REQUIRED" || status == "AGE_CHECK_REQUIRED" || status == "LOGIN_REQUIRED")
{
    var videoId = playerResponseJson.SelectToken("videoDetails.videoId")?.Value<string>();
    string postData = "{context:{client:{clientName:\"WEB\",clientVersion:\"2.20210827.01.00\",clientScreen:\"EMBED\"},thirdParty:{embedUrl:\"https://www.youtube.com/\"}},playbackContext:{contentPlaybackContext:{signatureTimestamp:18865}},videoId:\""+ videoId + "\"}";
    var data = Encoding.ASCII.GetBytes(postData);
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://www.youtube.com/youtubei/v1/player?key=AIzaSyAO_FJ2SlqU8Q4STEHLGCilw_Y9_11qcW8");
    request.Method = "POST";
    request.ContentLength = data.Length;

    using (var stream = request.GetRequestStream())
    {
        stream.Write(data, 0, data.Length);
    }

    var response = (HttpWebResponse)request.GetResponse();
    var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();

    Console.WriteLine(responseString);

    playerResponseJson = JToken.Parse(Json.Extract(responseString));
}

under line 72 in YouTube.cs.

It works for me
