86.3 TV Recording
Lets record some TV to an mpeg file. First, get the receiver running on the station you want:
$ tzap -r "SBS"Then capture the output from the device directly to a file!
$ cat /dev/dvb/adapter0/dvr0 >| sbs.tsA useful and simple program for the command line to record TV programs was written by Greg Lehey and is available from http://www.lemis.com/grog/programs/record/record.tar.gz.
Obtain this and extract to a folder:
$ wget http://www.lemis.com/grog/programs/record/record.tar.gz
$ cd recordI had to change a couple of things in record.c to get it to
work for me.
First, tzap is located as /usr/bin/tzap rather than
/usr/local/bin/tzap. Replace
char tzap [PATHMAX] = "/usr/local/bin/tzap"with
char tzap [PATHMAX] = "/usr/bin/tzap"The list of TV stations needs to be changed to suit yourself. The
author lives in Adelaide, South Australia, so he’s hardwired his
stations for his location. Look for the string dvbchannels in
record.c. The format is straightforward. Change the first
three strings in each row to reflect the stations available in your
area.
Next, the version of tzap from dvb-utils does
not have a -S (silent) option, so simply remove that line
from record.c:
"-S", /* be silent */Then compile the program:
$ makeAnd install either for your system (into /usr/local/bin) or
for yourself (into ~/bin):
$ sudo cp -p record /usr/local/bin/
$ cp record ~/bin/Now we are ready to record. Here’s some examples:
$ record abc news.ts -s 19:00 -e 19:30 # Start at 7pm End at 7:30pm
$ record abc late.ts -s 22:35 -t 00:30 # Start at 10:35pm for 30 minutes
$ record abc now.ts -t 0:1 # Record now for 1 minuteYour donation will support ongoing availability and give you access to the PDF version of this book.
