Hello all,
(I send this message again because I forgot to add the subject. Sorry.)
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 only when I store it 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
Is it possible to grab audio and video from two USB devices and send
it to ffserver?
Is there any good way to inspect the problem?
Thank you
Takeshi
