是否可以通过随机网址创建视频缩略图? 我有一些视频链接,我想从该视频制作缩略图并将缩略图保存在本地存储上。如果有可能的方法吗?

以下是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;
}
