I'm trying to overlay a logo on my Axis webcam stream using ffmpeg and
ffserver. The overlay seems to work fine when output is a file but when
I send the output to ffserver the video displays but the logo is nowhere
to be found. I'm using Centos 6.3 and a new git version of ffmpeg. The
only version I've been able to make this work on is ffmpeg-0.8.7 but the
video isn't as smooth and cuts out frequently.
My commands:
ffmpeg -i rtsp://root:password@192.168.1.5/axis-media/media.amp -vf
"movie=/home/webcam/logo/glow.png [logo]; [in][logo]
overlay=10:main_h-overlay_h-10 [out]" http://localhost:8090/feed1.ffm

The connection refused messages might be a clue but the main video
streams fine and looks great.
Any help would be greatly appreciated!
