[FFmpeg-user] Live stream re sync issue

Hi All, 

I am doing live streaming through ffmpeg command and publishing to IIS using the below command. 

-re -i D:\Test.MXF -r 25 -g 100 -force_key_frames expr:gte(t,n_forced*10) -s 320x180 -an -vcodec libx264 -vprofile main -pix_fmt yuv420p -x264opts bitrate=200:no-deblock:subq=6:partitions=all:8x8dct:me=umh:frameref=5:bframes=3:b_pyramid=normal:weight_b -movflags isml+frag_keyframe -f ismv http://sslivestream01.startv.com/LIVE_STREAM_PUBLISHPOINTS_WS/PPP000069587--20140731082705033--CS--1014.isml/Streams(Encoder400) 

Sometimes due to some network issue it is failing to create publish point and hence I am bound to re-execute the command and hence I am getting a time delay between the actual live feed and IIS streaming. 

I want to re-sync the input with the IIS streaming for the delay case. 

Please advice me any command can fulfill this requirement. 

Thanks in advance.
