This is a guide to setting up your GNU/Linux computer as a VCR. Setting up my VCR took a little research, but it
|
||||
didn't turn out to be as difficult as I thought. I decided to publish my results so others may benefit from what
|
||||
I've done. This is by no means the only method to achieve the same results as there are several applications out
|
||||
there that may perform similar tasks. Hopefully any unique procedures for configuring other software or devices
|
||||
may be incorporated into this document.

This section describes the different technologies used to build your own Linux VCR.
|
||||
|
||||
<sect1>Tuner or Capture Card
|
||||
<p>
|
||||
You will need to install a supported video4linux capture card in your computer. I currently use the Hauppauge
|
||||
WinTV tuner card which I purchased from Best Buy, but many other cards should work just as well. I don't have
|
||||
a suggestion for which is best, I can only comment that the one I own works for me.
|
||||
|
||||
<sect1>Kernel video4linux driver
|
||||
<p>
|
||||
Many GNU/Linux distributions already provide a Linux kernel that is configured to support video4linux devices.
|
||||
The Hauppauge WinTV card is supported by the 'bttv' driver. I have to load two modules into the linux kernel
|
||||
to support my card, namely the 'tuner' and 'bttv' modules. Check out the <url url="http://roadrunner.swansea.linux.org.uk/v4l.shtml" name="V4L homepage"> for details on
|
||||
supported tuner cards.
|
||||
<p>
|
||||
|
||||
<sect1>Frame Capture Software
|
||||
<p>
|
||||
Recording with your digital VCR of course requires frame capture software. As I become aware of available software
|
||||
for capturing audio/video to mpeg/avi formats, I will place it in this list. If you have any suggestions for good
|
||||
software please let me know and I'll add it here.
|
||||

||||

|
||||
Now lets go through the steps of actually configuring your computer as a VCR.
|
||||
|
||||
<sect1>Install and Configure Tuner Card
|
||||
<p>
|
||||
My particular tuner card required special parameters to the 'tuner' and
|
||||
'bttv' modules because it was an older model and wasn't properly auto-detected.
|
||||
If you can watch TV through your card via xawtv, then you have correctly
|
||||
configured your card. Here are the configuration lines from my /etc/modules.conf
|
||||
(or /etc/conf.modules for older distributions).
|
||||
<verb>
|
||||
options -k bttv radio=1 card=2
|
||||
options -k tuner debug=0 type=6
|
||||
</verb>
|
||||
These parameters will vary depending on the model of your card, see the documentation
|
||||
found in the linux source (linux/Documentation/video4linux) to figure out exactly
|
||||
how to configure your card. I added these modules to /etc/modules so they would
|
||||
automatically load on bootup. You can also manually load them with 'modprobe modulename'
|
||||
as root. I'm currently using the 2.4.2 kernel, but I have had success with this
|
||||
card with all of the 2.2.x kernels as well. Hint: the user may need to have
|
||||
ownership of the /dev/video /dev/video0 files (and maybe other devices as well)
|
||||
before the tuner card will function. As always, I suggest not running any apps
|
||||
as root.
|
||||
|
||||
<sect1>Configure xawtv to function properly.
|
||||
<p>
|
||||
You can either use xawtv from a reasonably current distribution, or download
|
||||
the source code from the <url url="http://www.strusel007.de/linux/xawtv/" name="xawtv Homepage">
|
||||
Make sure xawtv functions for your tuner card before proceeding.
|
||||
|
||||
<sect2>Sample .xawtv configuration file.
|
||||
<p>
|
||||
Here is a sample ".xawtv" configureation file. This should be placed within the
|
||||
home directory for the user who will be doing the VCR recording. I suggest adding
|
||||
presets to your .xawtv file for all channels(0-NNN) (even non-existing ones) because you
|
||||
will use the "v4lctl" command to switch channels later. This command makes use
|
||||
of 'preset number' rather than 'channel number', so it's conveniant to have preset
|
||||
numbers be the same as actual channel numbers. The following configuration file
|
||||
was designed for US-cable, your mileage may vary.
|
||||
<verb>
|
||||

|
||||

<sect1>Install the avifile library
|
||||
<p>
|
||||
Download the latest avifile package from <url url="http://divx.euro.ru" name="DiVX :-) Homepage">.
|
||||
You will need avifile-0.5x and binaries-xxxxxx.zip. You should extract the binaries to
|
||||
/usr/lib/win32. The next section describes compiling and installing avifile-0.53-5.
|
||||
<p>
|
||||
|

# cd avifile-0.53-5

|
||||
# cd /usr/lib/win32
|
||||
# unzip /path/to/binaries-010122.zip
|
||||
</verb>
|
||||
You will need to be root for the make install step to work.
|
||||
If you receive any errors, they were probably due to a missing dependancy during
|
||||
the configure step. Resolve any dependancies and try again. This should work
|
||||
smoothly on any recent distribution that was installed with 'development' tools.
|
||||

<sect1>Installing the VCR frame-grabber program
|

<p>
|
||||
You can get the latest vcr program (vcr-1.05 at the time I wrote this) from
|
||||
<url url="http://www.stack.nl/~brama/vcr/" name="The VCR Homepage">.
|

<p>

<sect2>Compiling and installing vcr-1.05

<p>
|

You will need to be root for the make install step to work.
|
||||
<verb>
|

# tar xvfz vcr-1.05.tar.gz
|
||||
# cd vcr-1.05
|
||||
# ./configure

# make
|

# make install

<p>
|
||||
</verb>
|
||||
|
||||
<sect2>Sample .vcrrc configuration file
|
||||
<p>
|
||||
By default, vcr installs everything into /usr/local (unless you changed the
|
||||
prefix on the ./configure line). You can now read the man page for
|
||||
vcr with: 'man -M/usr/local/man vcr'. This is where I got the initial
|
||||
.vcrrc file. I configured this one for my needs and added the same presets
|
||||
to this file as I did with the .xawtv file. If you think these files look
|
||||
similar, it's because I believe vcr was originally based on the xawtv code base.
|
||||
Here is the .vcrrc I use:
|
||||

<sect1>Using cron to record your favorite program.
|
||||
<p>
|
||||
You may want to verify vcr will record your program before setting up cron to
|
||||
record your programs. You can test this by doing "vcr -t 2m test.avi", then
|
||||
try to play back that two-minute sample using aviplay. Note that you will need to add
|
||||
'/usr/local/bin' to your path and '/usr/local/lib' to your ld library path for this
|
||||
to work properly. It was also suggested that you can use 'at' to record your
|
||||
program as well, this may be useful for times when you just want to record a
|
||||
program once at a specific time, but not regularly. Here is a sample shell
|
||||
script that can be called from cron:
|
||||
|
||||
<sect2>Sample cron shell script
|
||||
<p>
|
||||
This is a very simple script that merely switches to a channel and records
|
||||
sixty minutes of a program to a date oriented filename. Place this in $HOME/bin
|
||||
of the user who will actually do the recording - since I am going to run it at
|
||||
6pm, I'll call it recordshow6pm.sh.
|
||||
<p>
|
||||
<verb>
|
||||
#!/bin/sh
|
||||
LD_LIBRARY_PATH=/usr/local/lib
|
||||
export LD_LIBRARY_PATH
|
||||
PATH=/usr/local/bin:$PATH
|
||||
export PATH
|
||||
|
||||
DATE=`date +%m%d%y`
|
||||
FILENAME=/path/to/myshow-6pm-$DATE.avi
|
||||
v4lctl setstation 3
|
||||
vcr -t 60m $FILENAME

|

<sect2>Calling the script from cron
|
||||
<p>
|
||||
Now it's time to call it from cron, monday through friday at 6pm. To do this,
|
||||
run the crontab -e command as the correct user and enter the following line:
|
||||
<verb>
|
||||
00 18 * * 1-5 /home/username/bin/recordshow6pm.sh

This is just a collection of what I believe are the most common
|
||||
questions people might have. Give me more feedback and I will
|
||||
turn this section into a proper FAQ.
|
||||
|
||||
<itemize>
|
||||
|
||||
<item>Q:Why don't I get audio when playing back recorded programs?
|
||||
<p>
|
||||
A: This could be due to several things. In order for audio recording to work,
|
||||
you must have the tuner card send output to the 'line-in' on your sound card.
|
||||
You must also use the mixer to enable the line-in on the sound card (if you hear
|
||||
sound while recording the show, it is probably enabled). I used to have my tuner
|
||||
card sound sent to my stereo receiver instead of the sound card, which was why I
|
||||
didn't get sound. Finally, it may be that the sound was recored properly, but your
|
||||
sound device is in use by another program (esd, licq, xmms, etc).
|
||||
|
||||
<item>Q: Why is my video very jumpy?
|
||||
<p>
|
||||
A: This may be due to a slow CPU. I currently haven't determined the exact
|
||||
requirements for recording with this method, I'm hoping user feedback will help
|
||||
me figure out what CPU is indeed required. I have a Duron 700 that seems to work
|
||||
fine, but I've heard that people with a 200-300mhz processor are unable to get
|
||||
smooth video.
|
||||
|
||||
<item>Q: Why is the audio/video out of sync?
|
||||
<p>
|
||||
A: This may be due to an incorrect FPS setting for your video type. For NTSC
|
||||
you will want to use 29.97. For PAL you will want to use 25. I still don't
|
||||
get perfect audio/video syncronization - but I can live with it. Hopefully this
|
||||
will improve over time.
