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 studentrÃ¥det

2009-03-11 23:40

Jeg har tro pÃ¥ Ã¥pen kanalkonseptet som -Frikanalen er et eksempel pÃ¥, der borgerne fÃ¥r anledning til Ã¥ -kringkaste sitt syn pÃ¥ en Ã¥pen og demokratisk mÃ¥te. Jeg er veldig -glad vi har fÃ¥tt gjort kanalen tilgjengelig i Ogg Theora, slik at alle -kan fÃ¥ tilgang til opptakene pÃ¥ web, og slipper Ã¥ mÃ¥tte installere MS -Silverlight for Ã¥ spille av opptakene.

- -

Frikanalen har en brokete historie, og dagens inkarnasjon er ikke -helt slik foreningen Ãpen kanal planla det for mange Ã¥r 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 Ãpen kanal) har saksÃ¸kt kulturdepartementet over -konsesjonsvilkÃ¥rene til Frikanalen. Jeg er spent pÃ¥ resultatet.

I arbeidet med Frikanalen med Ã¥pne standarder, sÃ¥ har vi hatt glede -av Ã¥ se en rekke av innslagene som er tilgjengelig. Her er mye -religiÃ¸st sludder, fra -vandring -i jerusalem via -religiÃ¸st -vinklede nyheter til -kreasjonisk -retorikk, men ogsÃ¥ fine -dokumentarer -om redningsselskapet og -interessante -tegneserieanmeldelser.
