怪了,Process.Start()提示找不到文件???
System.Diagnostics.Process   pro;
                pro   =   new   System.Diagnostics.Process();
                pro.StartInfo.FileName   =   "d:\\ffmpeg\\ffmpeg.exe   -i   \ "d:\\ffmpeg\\jq.mpg\ "   -ab   56   -ar   22050   -b   500   -r   15   -s   320x240   \ "d:\\11.flv\ " ";
                pro.Start();


运行错误,找不到文件但改成
pro.StartInfo.FileName   =   "d:\\ffmpeg\\ffmpeg.exe "
就能运行  


------解决方案--------------------
把参数加在pro.StartInfo.Arguments 里试试
