I don't know if my question is in this or ffmpeg forum, I'm sorry if
isn't correct forum.

I have this problem:
I compiled ffmpeg an ffmserver for a ARM processor, and works fine.
I can run this apps on my embedded system and streaming video over net.

I use this ffserver.conf:

Port 8090
MaxClients 5
MaxBandwidth 10000

I can streaming video file with this this instruction:

ffmpeg -i file.avi -r 24

When I try to use this instruction for use a webcam:
ffmpeg -f video4linux  -s 320x240 -r 5 -i /dev/video0

I get this:

I don't know what means OVERHEAD INF, I'm looking for and I don't find anything about this.

I have some questions:

Is this a error message? What's means this error?
How can I fix it?

Thanks for your help.
