SIP/SDP中的H.264 SPS/PPS语法 [英] Syntax of H.264 SPS/PPS in SIP/SDP offer

问题描述

根据RFC 6184:

According to RFC 6184:

H.264的附件B定义了一种封装过程来传输 面向字节流的网络上的NALU.在此范围内 备忘录，附件B不相关.

Annex B of H.264 defines an encapsulation process to transmit such NALUs over bytestream-oriented networks. In the scope of this memo, Annex B is not relevant.

我看到了很多这样的SPS/PPS的examplex，包括RFC6236

I see a lot of examplex, including in RFC6236, of SPS/PPS like this

a=fmtp:99 packetization-mode=0;profile-level-id=42e011; \
      sprop-parameter-sets=Z0LgC5ZUCg/I,aM4BrFSAa  

但是，根据H.264，附件B，不应使用逗号，并且必须在SPS和PPS的开头都添加一个序言(然后将SPS/PPS转换为基数64).

However, according to H.264, Annex B, there should be no comma, and a preamble must be added to the beginning of both SPS and PPS (and after that SPS/PPS is converted to base 64).

所以我不知道该怎么做.

So I don't understand what is the right thing to do.

推荐答案

逗号应该在这里.前缀仅适用于MPEG-2.

comma should be there. prefix is for MPEG-2 only.
