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.
