我想捕获视频并上传到服务器，我已经完成了捕获视频的代码并将其显示到视频视图并且其运行成功，我想扩展它以将此捕获的视频上传到服务器。 我正在使用asp.net网络服务来做到这一点。 这是我的代码

使用此功能通过ftp上传...
SimpleFTP ftp = new SimpleFTP();
// Connect to an FTP server on port 21.
ftp.connect("server address", 21, "username", "pwd");
// Set binary mode.
ftp.bin();
// Change to a new working directory on the FTP server.
ftp.cwd("path");
// Upload some files.
ftp.stor(new File("your-file-path"));
// Quit from the FTP server.
ftp.disconnect();
