Hi Nanang, I must admit that I did't check the recent revisions ... So sorry for spreading unverified information. But after the upgrade to the 3972 rev (http://trac.pjsip.org/repos/changeset/3972/pjproject/trunk), I had such a problem. When I set the encoder resolution (720x480) at exactly the same "resolution" that allowed me the profile-level-id (eg 42e01e) and make video call between the two pjsua_app, there are video windows but no picture inside. (I received RTP packets on both sides, but nothing came to the SDL device) after increasing encoder resolution of one problem is gone. And since then, the video calls for all I tested profile-level-ids and encorder resolitions works as I expected. Tomorrow I'll try to check it out. BR Andrew
