推荐答案

您必须从上传的视频中删除一个帧！

you have to take a frame out of your uploaded video!

Process p;
ProcessStartInfo info = new ProcessStartInfo();
info.FileName = "ffmpeg.exe";
info.WindowStyle = ProcessWindowStyle.Hidden;
info.Arguments = " -i " + your_video_name + " -vframes 1 " + your_extracted_image_name + "%d.jpg";


p = Process.Start(info);


while (!p.HasExited) { Thread.Sleep(10); }

视频的地址应该是这样的:"c:\ inetpub \ wwwroot \ mysite \ videos \ video_to_convert.3gp"
"-vframes 1"占据视频文件的第一帧！
％d.jpg":％d是ffmpeg.exe的参数，可对新图像进行自动编号，
然后保存您的图片，然后使用本文制作水印图片！
