[FFserver-user] Try to publish an mxg stream to ffserver

[David Siegel]

I'm pretty new to this, and would appreciate some getting started help.
The command I issue is as follows:

 ffmpeg/ffmpeg -f mxg -i "http://cam/control/faststream.jpg?stream=MxPeg"
http://localhost:8090/feed1.ffm

The error I receive is this:
