Greetings! I am trying to stream a webcam using FFServer and I'm running
into this error when I execute the command:
ffmpeg -s hd720 -f video4linux2 -i /dev/video0
http://localhost:8090/feed1.ffm
I get
HTTP error 404 Not Found http://localhost:8090/feed1.ffm: Input/output error
Visiting the status page on the machine running FFServer lists the stream
and the associated feed1.ffm, so FFServer is running and bound to the port.
This is on a BeagleBoard, so there's weirdness involved, but I'm not sure
why.
Any suggestions as to what else I could try or how I might go about further
debugging this?
Thanks!
