I am using TweetInvi to post video on Twitter.
TwitterCredentials.SetCredentials(token.Token,token.TokenSecret,ConfigurationManager.AppSettings["ConsumerKey"], ConfigurationManager. AppSettings["ConsumerSecret"]);
var filePath = string.Format("{0}content\\participant\\video\\{1}.{2}", Request.PhysicalApplicationPath, p.video, "mp4");
byte[] file1 =System.IO.File.ReadAllBytes(filePath);
var tweet = Tweetinvi.Tweet.CreateTweet(message);
tweet.AddMedia(file1, "video");
var success = tweet.Publish();
Tweet is posting successfully. But video file is missing. I have used code from tweetinvi twwet with media
Thanks in advance.
