[streaming] Reg:H.264 video streaming

[Thomas Christensen]

Well I noticed the 0.8.6c line in the sdp.
I'm using 0.8.6a and when I use the sdp generated by my vlc I get an  
image with artifacts and it's all sort of dimmed. When I use the  
following line from you sdp:
a=fmtp:96 packetization-mode=1;profile-level-id=4d4033;sprop-parameter- 
sets=Z01AM7kYFgJNgQgAAAMACAAAAwGUeMGJwA==,aO48gA==;
the image turns completely green.

My sdp file (yes I'm currently using normal mpeg audio - haven't got  
the AAC libs on my box yet):
v=0
o=- 1193866005708667 2 IN IP4 127.0.0.1
s=NONE
t=0 0
a=tool:vlc 0.8.6a
c=IN IP4 172.27.1.2
m=audio 8192 RTP/AVP 14
a=rtpmap:14 MPA/90000
b=AS:96
m=video 8190 RTP/AVP 96
a=rtpmap:96 H264/90000
a=fmtp:96 packetization-mode=1;profile-level-id=4d4033;sprop-parameter- 
sets=Z01AM7kYFgJNgQgAAAMACAAAAwGUeMGJwA==,aO48gA==;
b=AS:800

Any ideas?

How did you btw set it up to used an old x264 lib?
