rtp payload list(转)
引用序：
在进行RTP传输相关流媒体时，RTP中有一个很关键的属性-payload(净荷类型),说穿了，这就相当于
邮局在寄信时，你可以标明是普通信件，特快专递，包裹等，只是作为标记这次传输的媒体类型。
我是这么理解的，如果有人有更好的理解，可以告诉我一声。应说它本身较简单，就不翻译了

Registry Name: RTP Payload Format media types
Reference: [RFC4855]
Registration Procedures: Standards Action Process or expert approval
Note:
In addition to the RTP payload formats (encodings) listed in the RTP
Payload Types table, there are additional payload formats that do not
have static RTP payload types assigned but instead use dynamic payload
type number assignment. Each payload format is named by a registered
media subtype as listed in the following table. As new payload formats
are specified, their registered media subtypes should be added to this
table. In addition, for the payload formats listed in the RTP Payload
Types table above, the "encoding name" is also registered as a media
subtype under the media type "audio" or "video". The clock rate and
number of channels shown here are the normal values for those payload
formats that have a normal value.
