Hi Muge, Oh that tutorial. Yeah i started off that tutorial. My implementation of video is very very similar. I use the commands buffer, VLC_Create(), VLC_Init(), VLC_ADDINTF(), etc. But i found the guide a bit too complicated/confusing and overloaded for what i wanted to do. Especially his definitions in the vlc.h file. Don't need all that. What i do is just get the remote IP, port, codec from remote_sdp and use a couple of VLC functions to stream and decode. Done. That tutorial i found was too much for what i simply wanted to do. Plus, i was never good at spanish. ;) Hubert On Wed, Oct 15, 2008 at 5:27 AM, P.Muge Ersoy <muge.ersoy at gmail.com> wrote: > Hi Hubert; > > I have a question for you .. > > Did you use the below tutorial for vlc display inside pjsip? > http://wiki.videolan.org/LibVLC_Visual_C > > > Muge > > > > On Tue, Oct 14, 2008 at 12:51 AM, Hubert Langevin <hubertlangevin at gmail.com> > wrote: >> >> Hello Muge, >> >> Yes my implementation sounds different.
