Não consigo enviar um fluxo para meu ffserver .
Eu iniciei o servidor com
ffserver -f /etc/ffserver.conf &
em que ffserver.conf não foi modificado. Eu tentei enviar um fluxo de webcam com
ffmpeg -f alsa -ac 2 -i plughw:0,0 -f video4linux2 -s vga -i /dev/video0 http://localhost:8090/feed1.ffm
No entanto, tenho o seguinte erro:
[...]
[tcp @ 0x560e1234c6e0] Connection to tcp://localhost:8090 failed (Connection refused), trying next address
[...]
MPEG-1/2 não suporta 3/1 fps
[...]
A porta 9080 está aberta, como visto com nmap localhost
Por que tenho esse erro e como enviar meu stream?
