Hi Hubert;
I tried your method of grapping ports and ip address and it works fine.
But when ever i start streaming i am not able to stream h264 .. it captured
my outgoing packages and see that my stream is mpeg2 (Payload type: MPEG-II
transport streams (33)) . So i am not able to see anything on the softphone
.. But it is working fine between two pjsua client..
I am sure you checked your stream if it is h264 didnt you ? May be 8.6c is
not supporting h264 i am not so sure ..
Btw Visual C example of vlc is not working on new API at all.. I tried VLC
9. 4 and VLC 8.6c .. Only 8.6c was worked with libvlc.dll export..
Are you using dll too ?
Also i d like to show my sdp file something like that ..
v=0
o=- 597327894206 2 IN IP4 192.168.0.165
s=NONE
t=0 0
c=IN IP4 192.168.0.165
m=video 14444 RTP/AVP 98
b=AS:28
a=rtpmap:98 H264/90000
