The second. The player's playback position is behind the actual live position by the mentioned latency value. > I just don't know, does iis streaming format have global metadata headers, > or not.

Also don't sure about global metadata headers, but AVOutputFormat for Smooth Streaming has AVFMT_GLOBALHEADER flag, so seems it has the global headers. Anyway my keyframes interval is as small as possible (every frame is keyframe). _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
