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

[dj_def at webmail.it]

I just found a workaround:

sudo ffmpeg -i input_video -i input_image -filter_complex "overlay=0:0"
-f avi pipe:1 | sudo ffmpeg -i pipe:0 http://localhost:9090/feed0.ffm

In this way the firsto output is like a file and is correctly processed.
The second input is the video with the image already applied.
