AMF协议里面的数据类型
详细的数据类型,参考Red5
FMS3中为了实现H.264数据的直播而增加了一个数据类型,这个类型的值为0×16,这个类型不在下表中,如果需要请参看

AMF是Action Message Format协议的简称，AMF协议是Adobe公司自己的协议，主要用于数据交互和远程过程调用，在功能上相当于WebService，但是AMF与WebService中的XML不同的是AMF是二进制数据，而XML是文本数据，AMF的传输效率比XML高。AMF使用HTTP方式传输，目前主要是用于ActionScript中，即实现Flex和Server之间的通信。

LikeDislikeAMF目前有两种版本，AMF0和AMF3，他们在数据类型的定义上有细微不同。关于AMF的官方文档参见：http://download.macromedia.com/pub/labs/amf/amf3_spec_121207.pdf
