[FFmpeg-user] Stream a video with a watermark or image over it

Tue Dec 11 20:45:31 CET 2012

 I want to stream a video with an image over it and I'm using this
 command:

 ffmpeg -i video.mp4 -i image.png -filter_complex
 "overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2"
 http://localhost:9090/feed0.ffm

 It works if I set a file output. How could I do this thing?

 I let you see a typical output that I get when trying to stream the
 video with the image applied on it.

         $ ffmpeg -i

 -i image.png -filter_complex 
 "overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2"
