关于上传大文件视频的问题 我做了一个网站,上传视频,大概三四G的mpeg文件。然后对其进行格式转换。转换能转,但是只能转一点点。我认为是文件太大了。所以想求一个方法解决问题。好想用ftp上传会好一点。那个高手给我指条道。最好给与我源代码。谢谢啊!!!! 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 通常的视频网站都是上传到一台转换机上去,这些转换机可能有几百台,甚至就是些pc,然后每个pc限定进程,通常不超过3~5个然后开始进行转换,转完了,再通知发布服务器。你在asp.net时转的话,基本是不太可能了。因为页面的个响应超时的限制。 给个FTP类给你吧public class FtpFile { string ftpServerIP;
