根据项目进展需要，我以前做的视频录制的程序（asp.net1.1+Ajaxpro）要部署到内部服务器上，并且程序转化为asp.net2.0+atlas，并架在两个机器上，WEB服务器+FMS。那面临的问题是视频缩略放在哪台服务器上，当然是放在WEB上最好了。
我决定在FMS上开webservice来解决两太机器协作问题:
webservice代码

这里工具还是以前选择的ffmpeg.exe来生成缩略图 这里放在了项目根目录ffmpeg\文件夹下继续处理web程序 是在录制成功后跳转的页面 用到了timer控件

运行测试一下 图片成功生成
开始录制:
提交后页面在处理中：
视频缩略图生成后：
新Blog，第一贴 以后都在这里写。嘿嘿，写给自己看。
