what is 'eth0'?

Obviously, this does mean that ffmpeg can't start listen for incoming
connection on port 5004. Do you have on your
I think it is very unlikely that -i udp:// is what you want. Because
using 'raw' UDP you can't 'establish connection' from PC to camera. This
is because there's no such a thing in UDP itself.
Roughly saying, with UDP, tranmitter side just blindly sends packets
from it's ip:port to receiver's ip:port without even knowing if there
receiver is present at all.
Doing this way, you theoretically must input your PCs ip:port
somewhere in camera settings, because this in the only way for camera
to know where to send packets (PC just can't 'connect' with 'raw' UDP).
That's why upper level protocol (running on top of UDP) is typycally
used for negotitating/establishing connection with camera, such as
rtsp, rtp...
So probably you need something like
ffmpeg -rtsp_transport udp -i
Look at your camera manual, if available, to find out which protocol
camera use.
