Sorry, I forgot to add the subject.
The subject should be

> Hello all,
>
> I am trying to
> grab audio from a USB microphone device and video from a webcam,
> and send it to ffserver.
> The audio codec is flac, the video codec is theora, and the container is ogg.
>
> I succeeded this when I store the video to a ogg file.
> However, I fail to send it to the ffserver.
> The error message is
> av_interleaved_write_frame(): Connection reset by peer.
> # I will put the whole error message below

> This is the ffmpeg command I tried:
> ffmpeg -f alsa -ac 7 -ar 16000 -i plughw:2,0 -f video4linux2 -i
> /dev/video0 -f ogg -r 10 -s 640x240 -ac 7 -ar 16000 -acodec flac
> -vcodec theora -loglevel debug http://localhost:8090/feed.ffm
>
> Questions are:
> 1. Would you give any ideas how to send or inspect the problem?
> 2. When I put "http://..." as the output, what protocol does ffmpeg uses?
> It seems that ffm format is used, but I couldn't find any document about it.
> From the ffserver log, it receives a GET request and a POST request
> for each file upload, and only one POST request for device upload.
> but I couldn't find any documents about the protocol.

> Thank you in advance,
