用jwplayer 播放swf，就去网上看了点资料(中文)，说支持。然后就在网站上找了demo。但所有无一例外都没有播放swf的，于是就怀疑······ 遂到官网上找，这是个大坑啊！！！！ 不支持swf！！！！
All – We do not support swf files. SWF is not a video format, it a Flash animation. Technically the files will play in the JW Player, but since SWF files generally have some interactive elements in them, we do not support them, as those will no longer be interactive if played through the player. If you are trying to embed a SWF file, it is recommended to just embed it without the player.
