[FFserver-user] ffserver cannot open ffserver.conf file

Thu Dec 1 09:59:58 CET 2011

Hello, I use ffserver & ffmpeg in order to generate a live stream
(recorded by a webcam).

I use an embedded processor (SH7724), busybox version 2010.09, kernel
2.6.39.3.

the command I issue is:

--------------------------------

 ffserver -f /etc/ffserver.conf & ffmpeg -v 2 -r 24 -s 640x480 -loglevel
verbose -f video4linux2 -i /dev/video0 http://localhost:8090/webcam.ffm

And the output of the command is:

--> It seems for me that ffserver does NOT open the conf file, hence
webcam.ffm file is NOT opened.

I've tried to move the conf file to some other path or to change its
name, but it wouldn't help.

I've also tried to remove the "-f /etc/ffserver.conf" (default location
is anyway /etc/ffserver.conf), but it also wouldn't help.

--> As far as I can tell the problem is that ffserver does NOT care
about its conf file (hence is not started).

Do you have any idea? I'm lost....

Thanks

The ffserver.conf file is:
