[Live-devel] waiting for SPS/PPS

I'm having an interesting bug,

I got Live555 working with a custom subclassed FramedSource, normally it's
been working fine.

However, it's part of a bigger project and I'm trying to get it to work on
it's own too so I can test individual changes easier.

It seems to be working fine but when I stream over RTSP, VLC is telling me
that it hasn't gotten the SPS/PPS. It seems like I'm generating it ok,
though clearly something is off. Perhaps you can tell me at what point the
SPS & PPS are actually sent? Maybe I'm skipping over it or something.

Here's what's being generated:
v=0
o=- 0 0 IN IP4 127.0.0.1
s=No Name
c=IN IP4 \video1\test.flv
t=0 0
a=tool:libavformat 58.44.100
m=video 0 RTP/AVP 96
a=rtpmap:96 H264/90000
a=fmtp:96 packetization-mode=1;
sprop-parameter-sets=Z00AKeKQDwBE/LgLcBAQHh4kRUA=,aO48gA==;
profile-level-id=4D0029
a=control:streamid=0

Anything stand out to you or any thoughts about this?

Thanks!
Matt
