[MEncoder-users] Using mencoder to stream to icecast

[Guillermo Salas M.]

Hello,

I'm trying to stream to an icecast server from my TV Caputure card (MSI
TV at Anywhere) using the following tools:

- mencoder
- ffmpeg2theora
- oggfwd


I'm capturing the channel 7 from the TV at Anywhere to an /tmp/pipe file
created with : mknod /tmp/pipe p


This is the command that I'm using to capture and stream:

mencoder tv://7 -tv driver=v4l2:device=/dev/video0:fps=29.97: \
chanlist=us-bcast:audiorate=16000:norm=NTSC:input=0:amode=1:  \
volume=100:channel=SE7 -ovc copy -oac copy -o /tmp/pipe - |   \
/usr/bin/ffmpeg2theora --artist "TV Manabi" --title "Stream de TV \
Manabi" --date "6-4-2008" --location "Manabi" --organization   \
"tvmanabi.com" --copyright "2008 tvmanabi.com" --license "creative \
 commons share alike" -x 320 -y 240 -F 25 -v 1 -a 1 -c 1 -H 22050 \
 -o /dev/stdout - | oggfwd -p -d "Stream de TV Manabi" -g "TV" \
-n "TV Manabi" -u "www.tvmanabi.com" my.icecastserver.com 8000 \
 mypassword /mountpoint.ogg


ffmpeg2theora uses the /tmp/pipe file and oggfw sent the capture to
icecast but... is not working :(

I can stream sending the output file to a normal output, for example:

mencoder tv://7 -tv driver=v4l2:device=/dev/video0:fps=29.97: \
chanlist=us-bcast:audiorate=16000:norm=NTSC:input=0:amode=1:  \
volume=100:channel=SE7 -ovc copy -oac copy -o /tmp/mycapure


I can grab the file /tmp/mycapure with ffmpeg2theora and send to
icecast with oggfwd, but the trouble is that the file /tmp/mycapure is
getting bigger and bigger.

Does any one knows how can I stream from the tv input to an icecast
server using theora but keeping the hard disk space? There is another
way to make it work?


Any help from you will be very appreciated.

Best regards,
