I am unable to send a stream to my ffserver.

I started the server with

ffserver -f /etc/ffserver.conf &

where ffserver.conf has not been modified. I tried sending a webcam stream with

ffmpeg -f alsa -ac 2 -i plughw:0,0 -f video4linux2 -s vga -i /dev/video0  http://localhost:8090/feed1.ffm

I have however the following error:

[...]

[tcp @ 0x560e1234c6e0] Connection to tcp://localhost:8090 failed (Connection  refused), trying next address

[...]
MPEG-1/2 does not support 3/1 fps
[...]

The port 9080 is open, as seen with nmap localhost

Why do I have this error and how to send my stream?

Full output:

# ffmpeg -f alsa -ac 2 -i plughw:0,0 -f video4linux2 -s vga -i /dev/video0  http://localhost:8090/feed1.ffm

I used another ffserver.conf found here to make this work:

# max number of simultaneous clients 

MaxClients 1000 

# max bandwidth per-client (kb/s)

# Suppress that if you want to launch ffserver as a daemon.
