I'm trying to create a streaming server using ffmpeg, and I'm stuck, so please advise if You can.
I've tested :

• ffmpeg-0.4.9_p20080326
• ffmpeg-0.4.9_p20070616

Both versions behave the same way. This is my emerge -pv ffmpeg
media-video/ffmpeg-0.4.9_p20080326  USE="a52 aac amr bindist debug doc encode imlib mmx mp3 network theora threads x264 xvid zlib -X (-altivec) -hardcoded-tables -ieee1394 -ipv6 -sdl -test -truetype -vorbis"

This command:
# ffmpeg -r 25 -s 352x288 -y -f video4linux2 -vc 1 -i /dev/video0 -f oss -itsoffset 00:00:00.500 -i /dev/dsp -isync -vcodec wmv1 -acodec wmav1 /tmp/test.wmv
gives me a perfect wmv file created from bt878 card and audio card

Unfortunatelly when I run:
# ffserver -f /etc/ffserver/ffserver.conf
# ffmpeg -r 25 -s vga -y -f video4linux2 -vc 1 -i /dev/video0 -f oss -itsoffset 00:00:00.500 -i /dev/dsp -isync http://localhost:8090/feed.ffm
I get no viewable steam from ffserver, although everything is encoding like it should (at least that is what shell tells me)

My ffserver.conf : (the important parts atleast)
