Hi Moritz,
Thanks for your replay. actually i have tried it without ffserver. I was successful to insert logo on .mp4 file which is not LIVE stream. but story of LIVE stream is different i think!  and  as far as i was not successful for live stream i do not have any output. by the way an example of my several tries is following link which was actually showing the stream without LOGO.How to add transparent watermark in center of a video with ffmpeg?

How to add transparent watermark in center of a video with ffmpeg?
 I am currently using these commands: Top left corner ffmpeg –i inputvideo.avi -vf "movie=watermarklogo.png...  |   |



my command was:ffmpeg –i -vf "movie=watermarklogo.png [watermark]; [in][watermark] overlay=(main_w-overlay_w-10)/2:(main_h-overlay_h-10)/2 [out]"

What exactly did you try and what was the complete, uncut console
output of it?

Perhaps you should first try without ffserver, just a few seconds to an
output file, to see whether it works.

Of course it's possible. And I don't know what you searched, but
google's first hit should work just fine!
