一回家就溫溫下Pure，聽日測，不時望望部電腦，不知道怎麼搞的，想起youtube這種東西都給好玩，如果在內聯網也加入youtube類似的功能，讓大家分享自己的短片，挺好玩。
當然，這要求server端有視頻轉換功能最好了。抱著絕望的心態去search，想不到竟然找到了。。

逐個逐個玩，先玩FFmpeg，挺復雜，再玩Turbine Video Engine,收費的，$390。下載試用了下，輸出flv文件總是0KB，放棄。再玩Mencoder，也總是輸出0KB。。。。。。無奈。
再玩回FFmpeg，終於，在不斷嘗試之下，hoho，成功輸出了flv文件，比flash 8自帶的快N倍。太好了，基本功能已實現，下一步就是要裝上server，並寫代碼實現相關功能。等明天考完先吧~~^^

找得我好辛苦的FFMpeg下載：
下載文件

點擊下載此文件
已包括pthreadGC2.dll文件。

轉換截圖：
請稍等，圖片正在下載中...

C:\ffmpeg\ffmpeg -i ying.wmv -ab 56 -ar 22050 -b 500 -r 15 -s 320x240 asf.flv

請稍等，圖片正在下載中...

續：
實在忍不住，書都不溫了，剛剛放入了server，並測試，調用代碼時，總是不能輸出，再把命令符放入server的執行程式裏，又能正常工作呀。。奇怪了。。
不行，再繼續試。。。。
又一輪功夫，發現程式的輸出地址必須絕對路徑(剛剛在本地，在server，相對地址都是ok的)。
在網頁程式裏調用則必須絕對地址，換上去。終於搞定了！！
有空開始把它正規化，並開始"營業"。。哈哈哈
