[Spam?] Re: Anyone know how to do a timed program with mplayer
and I've successfully recorded (using scripts and at) fixed-duration
RealPlayer radio shows to .wav to listen to them later. But I'd
like to record a specific show tonight from the continuous live ogg
stream.
In case anyone else cares, here's what I developed.
$ at 16:00
record-wuvt 15 15
for example, should produce files wuvt--20051115-1600.mp3 and
wuvt--20051115-1615.mp3, both just under 15 minutes long
(unfortunately you lose a few seconds between segments).
HTH someone,

I think it's better to kill elegantly with killall -3 mplayer. You could also try mencoder -oac copy -endpos mm:ss, although if I recall correctly mencoder doesn't or pure audio well (since after all the m is supposed to stand for movie.). -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Interesting, thanks.
As I said it's not the neatest, but it's neater than killall mplayer

Actually, a friend sent me a link to this site
http://osl.iu.edu/~tveldhui/radio/
Linux Radio Timeshift HOWTO
which includes the following slightly more sophisticated version of
killall in a sample script.
vsound realplay http://www.bbc.co.uk/cgi-bin/...
VSOUND_PID=$!
sleep 3660
kill `ps | grep realplay | awk '{ print $1 }'`
# Wait for vsound to terminate, creating vsound.wav
wait $VSOUND_PID
But there is a big difference between realplay and mplayer. Mplayer has
much cleaner sound. With vsound you get sound AND recording, can you do
that with mplayer?

With vsound you get sound AND recording, can you do that with mplayer? With mplayer, you can record sound from a stream as part of a batch job without an X display, so you can (for example) run a script from at while you're logged out. mplayer -really-quiet -ao pcm:file=foo.wav 'rtsp://example.com/foo.ra' lame --quiet foo.wav foo.mp3rm foo.wav -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

I've done just that to listen to KUSC at 2AM and stop at 5AM. But I did it with two commands I implemented with Qt: do_sm and do_km. Crontab starts do_sm at 2AM and it spawns mplayer to record. Crontab starts do_km at 5AM and it finds the record with the PID of do_sm and kills it with a TERM, which mplayer gets and terminates. Very elegant, but only because I did it that way of course ;-) If you want I can send you the code but don't respond to the from address but to hugovanwoerkom at yahoo dot com. Care2 is the pits. This prompts the question again: can you list and record at the same time with mplayer? H -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?
