    Recording video from cron using VLC
    +
    2009-04-05 10:00
    +
    +

    One think I have wanted to figure out for a along time is how to +run vlc from cron to do recording of video streams on the net. The +task is trivial with mplayer, but I do not really trust the security +of mplayer (it crashes too often on strange input), and thus prefer +vlc. I finally found a way to do it today. I spent an hour or so +searching the web for recipes and reading the documentation. The +hardest part was to get rid of the GUI window, but after finding the +dummy interface, the command line finally presented itself:

    + +
    URL=http://www.ping.uio.no/video/rms-oslo_2009.ogg
+SAVEFILE=rms.ogg
+DISPLAY= vlc -q $URL \
+  --sout="#duplicate{dst=std{access=file,url='$SAVEFILE'},dst=nodisplay}" \
+  --intf=dummy
    + +

    The command stream the URL and store it in the SAVEFILE by +duplicating the output stream to "nodisplay" and the file, using the +dummy interface. The dummy interface and the nodisplay output make +sure no X interface is needed.

    + +

    The cron job then need to start this job with the appropriate URL +and file name to save, sleep for the duration wanted, and then kill +the vlc process with SIGTERM. Here is a complete script +vlc-record to use from at or cron:

    + +
    #!/bin/sh
+set -e
+URL="$1"
+SAVEFILE="$2"
+DURATION="$3"
+DISPLAY= vlc -q "$URL" \
+  --sout="#duplicate{dst=std{access=file,url='$SAVEFILE'},dst=nodisplay}" \
+  --intf=dummy < /dev/null > /dev/null 2>&1 &
+pid=$!
+sleep $DURATION
+kill $pid
+wait $pid

    Frikanalen og jul i studentrådet

    -

    I går -lanserte -NUUGs videogruppe -Frikanalen med -åpne -standarder, og resultatet av noen intense uker med arbeide kunne -endelig presenteres. Jeg har tro på åpen kanalkonseptet som -Frikanalen er et eksempel på, der borgerne får anledning til å -kringkaste sitt syn på en åpen og demokratisk måte. Jeg er veldig -glad vi har fått gjort kanalen tilgjengelig i Ogg Theora, slik at alle -kan få tilgang til opptakene på web, og slipper å måtte installere MS -Silverlight for å spille av opptakene.

    - -

    Frikanalen har en brokete historie, og dagens inkarnasjon er ikke -helt slik foreningen Åpen kanal planla det for mange år siden, noe som -er bakgrunnen for at det fredag 13. mars 2009 kl 09:00 starter en -rettsak i Oslo tingrett der Kringkasterforeningen (tidligere -foreningen Åpen kanal) har saksøkt kulturdepartementet over -konsesjonsvilkårene til Frikanalen. Jeg er spent på resultatet.

    - -

    I arbeidet med Frikanalen med åpne standarder, så har vi hatt glede -av å se en rekke av innslagene som er tilgjengelig. Her er mye -religiøst sludder, fra -vandring -i jerusalem via -religiøst -vinklede nyheter til -kreasjonisk -retorikk, men også fine -dokumentarer -om redningsselskapet og -interessante -tegneserieanmeldelser. Det jeg derimot har hatt størst glede av, -er - -jul -i studentrådet, der hver episode var en fest å se på. Jeg håper -NUUG lykkes med å få ut sine opptak med like stor suksess.

    + Recording video from cron using VLC +
    +
    + 2009-04-05 10:00 +
    + +
    + +

    One think I have wanted to figure out for a along time is how to +run vlc from cron to do recording of video streams on the net. The +task is trivial with mplayer, but I do not really trust the security +of mplayer (it crashes too often on strange input), and thus prefer +vlc. I finally found a way to do it today. I spent an hour or so +searching the web for recipes and reading the documentation. The +hardest part was to get rid of the GUI window, but after finding the +dummy interface, the command line finally presented itself:

    + +
    URL=http://www.ping.uio.no/video/rms-oslo_2009.ogg
+SAVEFILE=rms.ogg
+DISPLAY= vlc -q $URL \
+  --sout="#duplicate{dst=std{access=file,url='$SAVEFILE'},dst=nodisplay}" \
+  --intf=dummy
    + +

    The command stream the URL and store it in the SAVEFILE by +duplicating the output stream to "nodisplay" and the file, using the +dummy interface. The dummy interface and the nodisplay output make +sure no X interface is needed.

    + +

    The cron job then need to start this job with the appropriate URL +and file name to save, sleep for the duration wanted, and then kill +the vlc process with SIGTERM. Here is a complete script +vlc-record to use from at or cron:

    + +
