[FFmpeg-user] how to insert logo over live stream

[Amir Amir]

Dear FFMPEG experts,

I would like to add an image as logo over a live stream and I have googled a lot with no success. I do not even figure out if this is possible or not? I have tried several options like -filter_complex and -vf filters but with no success.
I really need help in this topic.
Thanks.

I use the following command to use FFMPEG for UNICAST stream transcode:
   
      - ffmpeg -i http://192.168.2.100:2003 http://192.168.2.100:8090/feed0.ffm
   -    


where 192.168.2.100:2003 is .TS stream comming from the MUMUDVB
