问题描述
根据RFC 6184:
According to RFC 6184:
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.
