Yes, it's real player. Please see my previous email as well about Windows. > The two SDPs are very different, because they describe two completely > different RTP sessions.

If there is no audio at all, it should not matter, or I'm incorrect? _______________________________________________ libav-user mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/libav-user
