85.3 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.ts
A 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 record
I 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
char tzap [PATHMAX] = "/usr/local/bin/tzap"
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
record.c. The format is straightforward. Change the first
three strings in each row to reflect the stations available in your
Next, the version of tzap from dvb-utils does
not have a
-S (silent) option, so simply remove that line
"-S", /* be silent */
Then compile the program:
And install either for your system (into
for yourself (into
$ 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 minute
