是否有任何可能的方法从随机url创建视频缩略图?我有一些视频的链接，我想从该视频的缩略图和保存在本地存储的缩略图图像。如果有可能的话?

视频缩略图从http url

这是youtube视频的解决方案:-

public string GetThumbnailsUrl(string url)// this url is your youtube video url
{
    string imgurl = "";
    if (url != "")
    {
        if (!url.ToLower().Contains("embed/"))//if not an embed URL
        {
            string v = url;
            if (url.Contains("?"))
            {
                v = v.Substring(v.LastIndexOf("v=") + 2);
                if (v.Contains("&"))
                    v = v.Substring(0, v.LastIndexOf("&"));
            }
            else
            {
                v = v.Substring(v.LastIndexOf("v/") + 2);
            }
            int i = 0;
            try
            {
                i = Convert.ToInt32(ConfigurationManager.AppSettings["ImageSize"].Trim());//ImageSize contains the size of image.... the value is like 0,1,2,3.....
            }
            catch { i = 0; }
            imgurl = "http://img.youtube.com/vi/" + v + "/" + i + ".jpg";
        }
        else//For embed URL
        {
            string[] sep = new string[1] { "embed/" };
            string[] ss = url.Split(sep, StringSplitOptions.None);
            string key = ss[ss.Length - 1];
            int i = 0;
            try
            {
                i = Convert.ToInt32(ConfigurationManager.AppSettings["ImageSize"].Trim());
            }
            catch { i = 0; }
            imgurl = "http://img.youtube.com/vi/" + key + "/" + i + ".jpg";
        }

    }
    return imgurl;
}
